Describe the bug
When I tried to use "https" for deep link working on android and iOS not working. Then I tried "unilinks" its working both. But sharing unilinks via sms not clickable. So I want to use "https" for deep linking

To Reproduce
I tried the scheme as "https" like below, its working on ANDROID and not working iOS. For iOS I already added "https://skillsdoctor.net/apple-app-site-association". still "https" not working.
IOS :

<key>CFBundleURLTypes</key>
	<array>
		<dict>
			<key>CFBundleTypeRole</key>
			<string>Editor</string>
			<key>CFBundleURLName</key>
			<string>skillsdoctor.net</string>
			<key>CFBundleURLSchemes</key>
			<array>
				<string>https</string>
			</array>
		</dict>
	</array>

ANDROID

            <!-- Deep Links -->
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data
                    android:scheme="https"
                    android:host="skillsdoctor.net" />
            </intent-filter>

            <!-- App Links -->
            <intent-filter android:autoVerify="true">
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data
                    android:scheme="https"
                    android:host="skillsdoctor.net" />
            </intent-filter>

Expected behavior
Either https/unilinks deep link should work on both platform.

Hi,

I wonder why the distinction was made between receiving values in the background and foreground.

Now you have to check if the initial deeplink was not null.

final initialLink = await getInitialLink();
if (initialLink != null) {
  ...
}

As well as also listen on the stream when a deeplink was received in the foreground.

getLinksStream().listen(...)

We implemented a simple wrapper inside our app which deals with this.
Only exposes 1 stream where all events are posted including the initial one.

I wondered if it was something you'd be interested in to include in the lib already?

The helper class itself.

import 'dart:async';

import 'package:rxdart/rxdart.dart';
import 'package:uni_links/uni_links.dart';

/// Adds a wrapper around the uni_links library.
class DeepLinkHelper {
  StreamSubscription<String> _deepLinkStreamSubscription;
  final BehaviorSubject<String> _deepLinkSink = BehaviorSubject();
  Stream<String> get deepLinkStream => _deepLinkSink.stream;

  DeepLinkHelper() {
    _postInitialLink();
    _deepLinkStreamSubscription = getLinksStream().listen(_deepLinkSink.add);
  }

  void _postInitialLink() async {
    try {
      final initialLink = await getInitialLink();
      if (initialLink != null) {
        _deepLinkSink.add(initialLink);
      }
    } finally {}
  }

  void dispose() {
    _deepLinkStreamSubscription.cancel();
  }
}

How to clear initialLink after redirect to another page?

because after redirect to another page and open previous page, initialLink still have data so redirect to another page again

Has anyone been able to get this to work on iOS with Swift enabled?

I'm using custom scheme and am testing
on my Google Pixel 2,
which is running the Android Q beta (but this is unrelated).

In my main() method, I've registed my getUriLinksStream() to navigate to a specific Page, SuccessPage, after my one and only deeplink comes through. This works on its own, but now I introduce the scenario where my LoginPage is opening up a browser through url_launcher for an OAuth2 flow, then when the deeplink comes back, there's a brief moment for which the LoginPage attempts to rebuild, and then when the Navigator comes along, I get an exception saying setState() or markNeedsBuild() called during build, because they're both interfering. How do I stop them from executing too quickly? Can I delay the stream action somehow?

I'm using a printer app that gets called from flutter print://somepath, then the printer app calls myapp://anotherpath, and then later my app calls print://yetanotherpath, and the printer app calls myapp://anewpath.

On the second call to my app, anewpath appears insdie getUriLinksStream().listen() which at some point calls Navigator.pushReplacementNamed and exits the function unexpectedly, so that no code after that will run. I haven't been able to see any exceptions since my device is connected to the printer when this error occurs.

Note that the first call to my app, anotherpath is treated exactly the same as anewpath, however without the bug appearing.

Expected behavior
The expected behavior is that Navigator.pushReplacementNamed works, and any code after that runs.

Additional context
Also note that this bug only happens on iOS, on an old iPad that I've been working with. The problem does not happen on my android devices, though on the android devices getUrlLinksStream isn't used because getInitialUri() actually works on them. getInitialUri() never works on this iPad.

I'm using https scheme and am testing
on my Android Emulator, which is running Android 6: Marshmallow.

They key thing is, I can get the _latestLink to change if it is everything else besides res['message']['access_token'], even res['status'].toString work, which is here in this example...

import 'dart:async';

void main() => runApp(new MyApp());

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State<MyApp> with SingleTickerProviderStateMixin {
  String _latestLink = "";

  StreamSubscription _sub;

  final _scaffoldKey = new GlobalKey<ScaffoldState>();

  @override
  initState() {
    super.initState();
    initPlatformState();
  }

  @override
  dispose() {
    if (_sub != null) _sub.cancel();
    super.dispose();
  }

  // Platform messages are asynchronous, so we initialize in an async method.
  initPlatformState() async {
      await initPlatformStateForStringUniLinks();
  }

  initPlatformStateForStringUniLinks() async {

    _sub = getLinksStream().listen((String link) async {
      if (!mounted) return;
      if(RegExp(r'(?<=authorization_token=)(.*)(?=$)').hasMatch(link)) {
        var res = await getToken(link);
        print(res);
        if(res['status']){
          setState(() {
            _latestLink = res['status'].toString();
            try {
            } on FormatException {}
          });
        }
      }
    }, onError: (err) {
      if (!mounted) return;
    });

    if (!mounted) return;
  }

  @override
  Widget build(BuildContext context) {

    return new MaterialApp(
      home: new Scaffold(
        key: _scaffoldKey,
        body: new ListView(
          shrinkWrap: true,
          padding: const EdgeInsets.all(8.0),
          children: <Widget>[
            new ListTile(
              title: const Text('Link'),
              subtitle: new Text('$_latestLink'),
            ),
            homeContent()
          ],
        ),
      ),
    );
  }
}
homeContent(){
  return Center(
      child: RaisedButton(
        onPressed: () async {
          const url = 'https://example.com/anotherPath?client_id=<my client id string, not posting here>';
          if (await canLaunch(url)) {
            await launch(url);
          } else {
            throw 'Could not launch $url';
          }
        },
        child: Text('Signin'),
      )
  );
}

getToken(link) async {
  var req = await http.get("https://example.com/path?client_id=<my client id string, not posting here>&secret=<my secret string, not posting here>&authorization_token=" +  RegExp(r'(?<=authorization_token=)(.*)(?=$)').stringMatch(link));
  var res = json.decode(req.body);
  return res;
}

This code is actually just the example stripped of things.

Any ideia what I might be doing wrong?

I'm using custom scheme and am testing on my iPad which is running iOS.

Running any code such as:
/usr/bin/xcrun simctl openurl xxxYYY999 "unilinks://host/path/subpath"
returns Invalid device: xxxYYY999

The id xxxYYY999 is what "flutter devices" returns as well as xcode devices and simulators.

i get uri when click link from gmail, skype, slack success. Button when i click url from facebook app, i can't get uri

Describe the bug
It was a long and tedious process to make code working on android also work on ios.

getInitialUri doesn't behave the same, as it's always null on iOS, whereas it always works on android. The workaround for me was to use getUriLinksStream().listen on iOs.

Static variables, such as myClass.myVar inside myfile.dart are forgotten in android when myappscheme://somepath is called from another app, but remembered on iOS.

• old iPad Mini from 2012, MD528ZP/A AND Samsung Galaxy Tab A 2016, SM-T580
• OS: iOS 9.3.5 AND Android 8.1.0

Expected behavior
For iOS and Android to work the same way.

We are using flutter web, desktop and mobile.

Has anyone gotten this to work with Flutter web ?

I have an app and until now two users reported that they aren't able to login (My app uses uni_links to get the response from OAuth).
after sending these users a custom build to debug the issue via sentry, I found that they were getting the getInitialLink as null.
In the majority of the userbase the app and uni_links works just fine (~10k users).
What I could find that these users share is that they are on Android and that the link was being called from chrome.
I wasn't able to find a way to reproduce the bug properly in my setup.
All that I could find out until now is that they use other apps that uses deeplinks (non flutter apps) and they work properly.
the pattern that I'm using right now for my app is
luzinha://login?code=########################

This is my configuration :

Flutter 1.0.0 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 5391447fae (3 months ago) • 2018-11-29 19:41:26 -0800
Engine • revision 7375a0f414
Tools • Dart 2.1.0 (build 2.1.0-dev.9.4 f9ebf21297)

As I understand it similar URL scheme architecture exists for desktops.
I am playing around with flutter desktop and would like to get uni links working for it. I think it is possible.

The main obstacle is getting good doc for Mac OS and Windows and Linux.
So my request is for more high quality info / links for how each platform does this.

The flutter desktop plugins API is usable now ( just went through a refactoring ).

Describe the bug
getUriLinksStream().listen((Uri uri) {

}
this method is invoked twice everytime the app is being called by scheme
I am using custom deep linking, not associated one..

To Reproduce
Steps to reproduce the behavior:

1. set up custom scheme
2. calling scheme:// in webpage javascript: windows.location = "scheme://";
3. code invoked twice

Expected behavior
code invoked once should be expected

Additional context

my code snipset as below:

Future initUniLinks() async {

try {
  String initialLink = await getInitialLink();
  getUriLinksStream().listen((Uri uri) {

    Map<String, String> query = uri.queryParameters;
    Map<String, dynamic> json = jsonDecode(query['json']);

    DeepLinkDao deepLinkDao = DeepLinkDao.fromJson(json);
    handleDeepLink(deepLinkDao);
  }, onError: (err) {
    var a = 1;
    var b = a + 1;
  });
} on PlatformException {
  // Handle exception by warning the user their action did not succeed
  // return?
}

}

I'm using https scheme and am testing on my Google Pixelbook, which is running Chrome OS v73.0.3683.88.

I am unable to get the app to open in response to a link when it is running on Chrome OS.

I'm not sure this issue necessarily falls in the scope of this library, but I imagine it is not super hard to fix. I have found what I think is a related issue for React Native, but I am new to developing Android apps, so at the moment I am not able to figure out the right way to trigger/handle the intent.

Good Afternoon.. I worked a few hours to generate an external link to the app. Deep link worked in one app and not in another. After quitting (dawn), I realized that the app that worked did not support androidx. I wonder if this is really what is preventing intents, because Manifest did not recognize intents-filter. Generated a "No Activity found" error. Is this error happening on androidx?

The title says it all. Now that flutter started supporting macOS, it would be create if this plugin also worked for it. (Or at least doesn't make the platform channel calls fail.)

Your library is really good its working fine when app creates a new instance while entering to the app through deep link but in my case when app existing in the background if i entered that app through some uri by deepLinking the getInitialUri() not fetching that url.

Hi there,

if you install url_launcher and uni_links and open up a stream to uni.getUriLinksStream().listen(print); and then url.launch("https://myserver/myredirect") which redirects to a scheme, such as myscheme:/?payload="foo", you will see the browser disappear (as expected) but no event is recoreded by uni_links. However, if you open your browser manually, and type myscheme:/?payload="foo" in the address bar, it will open the app and uni_links will fire the event to console.

Short version: if you're using uni_links to listen for oauth2 redirects, the events do not fire. But if you use it any other way, it seems to work.

Do you have any suggestions for listening for these events?

I could be wrong but I don't believe this package is setup for AndroidX. Can you please confirm either way?

What is the difference between UriLinks and Links?

When using Universal link in IOS the listener getUriLinksStream is receiving the the link correctly, but getInitialUri is not reiceving it. Any idea and what could cause this issue?

I'm using https scheme and am testing on my Android Phone which is running Android 9.

I registered the .well-known/assetlinks.json in my domain.

Running the following from a local shell works fine and hits the callback within the app:
adb shell 'am start -W -a android.intent.action.VIEW -c android.intent.category.BROWSABLE -d "https://xxxxx.app/?code=123"'

BUT when an OAuth window redirects to https://xxxxx.app/?code=123 nothing happens.

Manually putting the https://xxxxx.app/?code=123 into the local browser only opens the website but does not open the App on my test phone, or when it already runs it does not hit the callback.

What can I do?

not a bug - this package is great. the problem i'm having, as someone who knows zero Swift, is how to support universal links when your Flutter app has Swift support enabled. there is no AppDelegate.m anymore, but rather an AppDelegate.swift. and there is now Runner-Bridging-Header.h instead of main.m and AppDelegate.h.

fyi, the only reason i had to include Swift support in the build is because of package contacts_service.

Logout (auth0.webAuth.clearSession()) Issues:

• If the user is signed in, it will logout the user but it will not return to the app. Instead, it will continue on to the login page on the web browser. And once logged in, it will proceed to the account profile page. Basically it is treated as a normal web session and will never exit the browser and return to the app.

• If the user is NOT signed in, it will crash and exit the app, without event throwing errors/exceptions.

Login (auth0.webAuth.authorize()) Issues:

• If the user is already signed in, it will crash and exit the app, without event throwing errors/exceptions.

We tried Universal links with https and it worked on our IOS devices but using Custom Schema didn't work on all app states ex foreground, background and suspended.

Appreciate your support

In your readme it states:

// NOTE: Necessary, until Flutter supports
// application:continueUserActivity:restorationHandler within the
// FlutterPlugin protocol.

I can see that Flutter now supports this callback: https://docs.flutter.io/objcdoc/Protocols/FlutterPlugin.html#/c:objc(pl)FlutterPlugin(im)application:continueUserActivity:restorationHandler:

Do we still need to add the ios related code?

Describe the bug
When build app with this plugin for ios, a buildtime show 2 warnings:

• UniLinksPlugin.h:4:4: pointer is missing a nullability type specifier (_Nonnull, _Nullable, or _Null_unspecified) [-Wnullability-completeness]
  Pointer is missing a nullability type specifier (_Nonnull, _Nullable, or _Null_unspecified)

  Block pointer is missing a nullability type specifier (_Nonnull, _Nullable, or _Null_unspecified)

Posible solutions generated for XCode
For two cases:

• Insert '_Nullable' if the block pointer may be null
• Insert '_Nonnull' if the block pointer should never be null

Additional context
This error happend in XCode build and in Codemagic.

I'm using unilinks and am testing
on my iOS Simulator
which is running iOS 13.

When i execute the command: ▶ /usr/bin/xcrun simctl openurl booted "lejour://profile"
i got this error: An error was encountered processing the command (domain=NSOSStatusErrorDomain, code=-10814):

I wanna know if have any way to catch this error and redirect to app store or play store in app page

Hello guys! I have a set of custom URL schemes that are triggered with push notifications.
Everything works fine with Android on all states (Open, Foreground/Background, Closed/Forced Quit). But not with iOS, which does not work when app is closed.

Everytime i close the app, force to open with a custom URL scheme, the app opens but the getInitialUri returns the uri as null, which is being called here:

main.dev

StreamSubscription uriSubscription;

  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  @override
  void dispose() {
    if (uriSubscription != null) {
      uriSubscription.cancel();
    }
    super.dispose();
  }

  Future<void> initPlatformState() async {
    debugPrint('com.fonixtelematics.app: initPlatformState');
    // if (!mounted) return;
    if (uriSubscription != null) {
      uriSubscription.cancel();
    }

    await pushService.init();
    uriSubscription = await URILinks().initStream();

    await URILinks().checkInitialURI();
  }

urilinks.dart

class URILinks {
  Future<StreamSubscription> initStream() async {
    return getUriLinksStream().listen(uriLinksHandler);
  }

  Future<void> checkInitialURI() async {
    debugPrint('com.fonixtelematics.app: checkInitialURI');
    return getInitialUri().then(uriLinksHandler).catchError((e) {
      debugPrint(
          'com.fonixtelematics.app: checkInitialURI ERROR ' + e.toString());
      navigatorKey.currentState.pushNamed(Routes.main);
    });
  }

  void uriLinksHandler(Uri uri) {
    debugPrint('com.fonixtelematics.app: uriLinksHandler ' + uri.toString());
    if (uri != null) {
      debugPrint('com.fonixtelematics.app: uriLinksHandler ' + uri.host);
    }
    if (uri != null && uri.host != null && uri.host.isNotEmpty) {
      switch (uri.host) {
        case 'auth':
          ...
          break;
        case 'alert':
          ...
          break;
        default:
          navigatorKey.currentState.pushNamed(Routes.main);
          break;
      }
    } else {
      throw (false);
    }
  }
}

Is anyone else having the same issue?

Both for Android and for IOS, I get this:
"Unhandled exception:
NoSuchMethodError: The getter 'host' was called on null

It appears in the verbose log.

Can I check somehow the way the application was started and then use the corresponding method?

I am using this tutorial to implement the plugin
https://peb.si/deep-links-flutter/
and it works perfectly with andriod, However, on ios the link does not direct me to the screen that I want to be displayed if the parameters matches the values that I have inserted in the method :

 void handleLink(Uri link) {
	var parameters = link.pathSegments;
	// we now have the parameters object to work with and can check the path segments!
	// e.g if we're sending https://peb.si/inbox/1 meaning 'open conversation #1' we can handle it like this:

	if (parameters[0] == "inbox" && parameters[1] != null) {
		Navigator.push(
			context,
			MaterialPageRoute(
				builder: (context) => ChatPage(
					id: int.parse(parameters[1]))));
	}
} 

and it just direct me to the home screen of the app instead.
How Can I solve this issue?!
Thanks in advance :)

Thanks!

why in the example does uni_links get specified under dev_dependencies instead of dependencies? i would think it would be the opposite. just wanting to confirm -- thanks.

I'm using [https scheme] and am testing
on my [iOS Simulator, Android Emulator],
which is running [iOS13.1, Android 10].

Works well on Android. However, doesn't work on iOS. I believe the only thing that sounded weird in the docs was

either through Xcode or by editing (or creating and adding to Xcode) ios/Runner/Runner.entitlements file

What is adding to Xcode? I simply created that XML file and placed it under ios/Runner. Do I need to do anything else in xcode?

Hi, I'm having trouble getting the uni_links plugin to provide the URI at startup using getInitialLink. While I can get it to trigger an event using a stream this doesn't work when the app is first open. I'm not sure if its a problem with the plugin or if I'm not doing something right. Could I get some help. I'm not getting any errors. the getInitialLink function is just returning null.

In the provided docs only the receiving part is shown, there's no docs of how an app A can start an app B using this library.

I'm using https scheme and am testing on my Android Emulator, which is running Android 9.0.

The getLatestLink method isn't implemented on android:
https://github.com/avioli/uni_links/blob/master/android/src/main/java/name/avioli/unilinks/UniLinksPlugin.java#L69

@Override
  public void onMethodCall(MethodCall call, Result result) {
    if (call.method.equals("getInitialLink")) {
      result.success(initialLink);
      // } else if (call.method.equals("getLatestLink")) {
      //   result.success(latestLink);
    } else {
      result.notImplemented();
    }
  }

It appears that this code has been commented out since inception of the file.

Is there a technical reason this cannot be enabled?

I can get uri from getUriLinksStream, but if the app launchs directly, the call doesn't return

getUriLinksStream It doesn't work under IOS and won't receive monitoring results.

Universal Links was working fine on iOS 12 but I ran into issues iOS 13.+
URLs that's supposed to open the app when tapped are just opening up in the browser and redirect to app store.

Please update possible solution ASAP.

which is running IOS12.1.

Hi, I'm trying to perform an OAuth scenario. I use the package launch_url to open the oauth authorization end point. There I provide my user credentials. Everything works fine. My app gets called back through the redirect uri that use my custom scheme and host but the safari browser stay open on top of the app with a blank page. I need to manually click on the top left corner OK button to close it and see my app. My app is not coming to the foreground with the deep link call back from safari. Any idea on how to resolve this?
Thanks for any help.

Great package thanks for this.

in android

adb shell 'am start -W -a android.intent.action.VIEW -c android.intent.category.BROWSABLE -d "unilinks://example.com/path/portion/?uid=123&token=abc"'

I can get the uid, but I cant not get the token

what's wrong with me?

I'm using android with flutter 1.7.8 and uni_links 0.2.0.

I added an intent to my android manifest to register deep links:

        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data
                android:scheme="shopli"/>

Now when I test this by using the adb shell and call:
am start -W -a android.intent.action.VIEW -c android.intent.category.BROWSABLE -d "shopli://shopli.sveri.de/d8c9e9a9-a04c-4c8c-aa68-104124333c8f"
my app is being notified and acts on it as expected.

But let's say I receive this link via email / messenger clicking on the link will open the browser which then tries to load shopli.sveri.de. I would expect it to open my app instead.

Am I missing something here?
