flutteroauth's Introduction

Flutter OAuth

A Flutter OAuth package for performing user authentication for your apps.

I've tested this with a small collection of APIs (Buffer, Strava, Unsplash and GitHub). If there is an issue with an API you are trying to work with, please file an issue :)

Authorizing an application

Performing authorization for an API is straight forward using this library. In most cases you will just be able to use the following approach:

final OAuth flutterOAuth = new FlutterOAuth(new Config(
    "https://unsplash.com/oauth/authorize",
    "https://unsplash.com/oauth/token",
    "YOUR_CLIENT_ID",
    "YOUR_CLIENT_SECRET",
    "http://localhost:8080",
    "code"));

This allows you to pass in an Authorization URL, Token request URL, Client ID, Client Secret, Redirect URL and the response type. This should satisfy most requests, but if not then you can pass in other optional parameters for:

contentType - This allows you to change the content type for the request. For example, for Spotify API authorization you need to use "application/x-www-form-urlencoded"

final OAuth flutterOAuth = new FlutterOAuth(new Config(
    ...,
    contentType: "application/x-www-form-urlencoded"));

parameters - Add your own parameters that this library may not support out-of-the-box. For example, with the GitHub API you can send a state string and scopes to gain authorization for

Map<String, String> customParameters = {"state": "SOME_RANDOM_SECURE_STRING", "scope": "public_repo"};

final OAuth flutterOAuth = new FlutterOAuth(new Config(
    ...,
    parameters: customParameters));

headers - Some APIs require you to send custom headers, such as an Authorization Header. Use this parameter if you require this

Map<String, String> headers = {"Authorization": "Basic SOME_BASE_64_STRING"};

final OAuth flutterOAuth = new FlutterOAuth(new Config(
    ...,
    headers: headers));

Then once you have an OAuth instance, you can simply call the performAuthorization() method like so to retrieve a Token instance:

Token token = await flutterOAuth.performAuthorization();
String accessToken = token.accessToken;

Installing

Add the following you your pubspec.yaml dependancies:

dependencies:
  flutter_oauth: "^0.0.1"

flutteroauth's Issues

Error message when adding flutter_oauth to dependencies

Every time that I enable flutter_oauth: "^0.0.1" in the dependencies in my pubspec.yaml I get the following message:

Error detected in pubspec.yaml:
#/properties/flutter: type: wanted [object] got null

The application runs and builds, though.

get state value

After succussfully get auth code how I can get state value for sending own server.

var result = await appAuth.authorize( AuthorizationTokenRequest( '$clientId', '$redirectUri', discoveryUrl: finalUrl, serviceConfiguration: AuthorizationServiceConfiguration(finalUrl, ""), scopes: ['profile'], ), );

Cann't use it on Dart 2.5.0

Running "flutter pub get" in smart_parking_flutter... The current Dart SDK version is 2.5.0.

Because smart_parking_flutter depends on flutter_oauth any which requires SDK version >=1.8.0 <2.0.0, version solving failed.
pub get failed (1)
Process finished with exit code 1

iOS behaviour

Thanks for this plugin. Tested the example on Android with Strava and works out of the box. Just checking if additional configuration is needed for this to work on iOS - specifically to refocus the flutter app. At moment, after entering facebook credentials I get stuck on a facebook loading screen.

Cheers.

Project Maintenance

Hi, this project currently it's not being maintained, right?

What would be the best option for the same? Are there any recommended forks?

Configurable local callback server

Hi,

API providers are sometimes very restrictive about redirect uris.
Please provide a way to customize the server parameters so that it can match every callback uri.
Especially the port number.

Doesn't work with Google

I'm trying to authenticate against a YouTube Google account. I get a 403 in the webview that says:

Error: disallowed_useragent

This user-agent is not permitted to make an OAuth authorization request to Google as it is classified as an embedded user-agent (also known as a web-view). Per our policy, only browsers are permitted to make authorization requests to Google...

Is there a workaround for this with this library? Any reason this library doesn't just open a browser?

What kind of config code do we need for Instagram auth?

Dart SDK version is 2.12.0

flutter_oauth any which requires SDK version >=1.8.0 <2.0.0

type 'Future<dynamic>' is not a subtype of type 'Future<Null>'

I tried to create a very basic example.
I just created a method like this and called it:
`Future _performOAuthLogin(String client_id, String client_secret) {
final OAuth flutterOAuth = new FlutterOAuth(new Config(
"https://localhost:8888/oauth/authorize",
"https://localhost:8888/oauth/token",
client_id,
client_secret,
"http://localhost:8080",
"code"));

return flutterOAuth.performAuthorization();

This code snippit leads to the following exception:
[VERBOSE-2:dart_error.cc(16)] Unhandled exception: type 'Future<dynamic>' is not a subtype of type 'Future<Null>' #0 FlutterWebviewPlugin.close (package:flutter_webview_plugin/flutter_webview_plugin.dart:73:36) #1 FlutterOAuth.requestCode (package:flutter_oauth/lib/flutter_auth.dart:26:21) <asynchronous suspension> #2 OAuth.performAuthorization (package:flutter_oauth/lib/oauth.dart:49:31) <asynchronous suspension>

Am i doing something wrong?

Does not work with current Flutter version (not compatible with Dart2)

[VERBOSE-2:dart_error.cc(16)] Unhandled exception:
type 'Future' is not a subtype of type 'Future'
#0 FlutterWebviewPlugin.close (package:flutter_webview_plugin/flutter_webview_plugin.dart:73:36)
#1 FlutterOAuth.requestCode (package:flutter_oauth/lib/flutter_auth.dart:26:21)

#2 OAuth.performAuthorization (package:flutter_oauth/lib/oauth.dart:49:31)

Doesnt work with latest flutter

Error message is:

The current Dart SDK version is 2.1.0-dev.5.0.flutter-a2eb050044.

Because flutter_app_delete depends on flutter_oauth any which requires SDK version >=1.8.0 <2.0.0, version solving failed.

Need to upgrade flutter webview plugin dependency

I'm getting errors related to a return type of Future within the flutter_webview_plugin. I checked that repo and those response types have been changed to a generic Future without the . I think you need to update the dependency number to get the latest flutter_webview_plugin.

Fitbit Api Oauth Issue

I am trying to connect to fitbit oauth, here is my code:

Map<String, String> customParameters = {"scope": "activity"};
final OAuth flutterOAuth = new FlutterOAuth(new Config(
"https://www.fitbit.com/oauth2/authorize",
"https://api.fitbit.com/oauth2/token",
"######",
"################",
"http://localhost:8080",
"code",
parameters:customParameters,
contentType: "application/x-www-form-urlencoded"));

But i keep getting a null return after I logged in and allowed access to app.

Faceit OAuth

Hi, I'm trying to use Faceit's OAuth Api with your example app but every time I hit authorize it tries to open this url: http://auth-api.team-platform/v1/oauth/login?client_id=CLIENT_ID&response_type=code&redirect_popup=false

Faceit's auth url is: http://api.faceit.com/auth/v1/oauth/authenticate
and the token url: http://api.faceit.com/auth/v1/oauth/token

FlutterOAuth.listenForServerResponse is not work on my MI 6 with Android 7.1

When I use FlutterOAuth , every thing is ok ,but cannot listen the request. So the webview can not be close successfully.
