How about ability to send fixed custom notification?

critical

I think by default, notifications should wait for an active notification to be dismissed before displaying the next one.

I can't see a case where someone would want to have a notification removed by another one without it running its course, honestly, so this behavior is a must!

有时候，顶部通知显示之后就不消失了，导致无法操作appbar上的按钮。希望能解决一下，我观察在ios上出现的概率比较高， 并且我在通知上加了手势监听也消失不小，应该是通知实例泄露了。

NotificationEntry showSimpleNotification2(BuildContext context, Widget content,
    {Widget leading,
    Widget subtitle,
    Widget trailing,
    EdgeInsetsGeometry contentPadding,
    Color background,
    Color foreground,
    bool autoDismiss = true}) {
  NotificationEntry entry;
  entry = showOverlayNotification(context, (context) {
    return Material(
      color: background ?? Theme.of(context)?.accentColor,
      elevation: 2,
      child: SafeArea(
          bottom: false,
          child: GestureDetector(
              onTap: () {
                entry?.dismiss();
              },
              child: ListTileTheme(
                textColor: foreground ?? Theme.of(context)?.accentTextTheme?.title?.color,
                iconColor: foreground ?? Theme.of(context)?.accentTextTheme?.title?.color,
                child: ListTile(
                  leading: leading,
                  title: content,
                  subtitle: subtitle,
                  trailing: trailing,
                  contentPadding: contentPadding,
                ),
              ))),
    );
  }, duration: Duration(milliseconds: 1000));
  return entry;
}

Now:

typedef Widget AnimatedOverlayWidgetBuilder(BuildContext context, double progress);

Should be:

typedef Widget AnimatedOverlayWidgetBuilder(BuildContext context, Animation<double> animation);

is any feature to show opacity curtain under notifications? like with dialogs

Describe the bug
Give me some code snippet for use.

#42 should report an error in this situation.

Is it possible to have the notification show at the bottom of the screen rather than the top? Is there something I could modify in the package to get it to show at the bottom instead of the top?

Currently, in the LICENSE file, the copyright information is not correct. It literally reads (in line 189):

Copyright [yyyy] [name of copyright owner]

Could you please add a valid year and name?

To Reproduce
Steps to reproduce the behavior:

1. just added in pubyaml
2. returned OverlaySupport
3. used showSimpleNotification

Version (please complete the following information):

• Flutter Version: Flutter 1.26.0-17.2
• OS: WEB
• OverlaySupport Version : ^1.0.5

you suppose i have textformfield on notification to get some information fro user, how can i get typed text from that?

Add Duration parameter to showSimpleNotification method, so that it can be a chosen value instead of a fixed duration.

Is it possible to dismiss any pending previous overlay before firing a new one?

Sometimes I fire a loading overlay and then the operation gets completed fast and shows a new overlay stating success, but the previous overlay (the one with the loading label) is still there behind the new one has shown up.

I want to be able to dismiss any pending or any other overlay is present in screen before showing the new one. is this possible? How can this be achieved based on a main context.

I have a an use-case where I have multiple Material apps and implicitly I need multiple OverlaySupport. How can I achieve this?

https://api.flutter.dev/flutter/material/MaterialBanner-class.html

I was wondering if you have any plan to add a feature that can swipe an overlayed notification to dismiss.

Thank you for this awesome plugin.

void _showDeletedSnackBar(String message, String itemCode, index,
      Map deletedItem, BuildContext context) {
    showSimpleNotification(Text(message),
        autoDismiss: true,
        position: NotificationPosition.bottom,
        leading: Icon(Icons.delete),
        background: Colors.redAccent,
        foreground: Colors.white,
        trailing: FlatButton(
          child: Text(
            'Recuperar',
            style: TextStyle(color: Colors.yellow),
          ),
          onPressed: () {
            OverlaySupportEntry.of(context).dismiss();
            context
                .read<CartDataProvider>()
                .addDeletedItemToCart(index, deletedItem);
          },
        ));
  }

Am I doing something wrong here?

ohhh, i got it... I modified the maximum line length to 120 in the settings.

alright, maybe I should take a look for dart's lint to avoid this kind of situation from happening again

It looks like OverlaySupport.global is always used even when there is a parent OverlaySupport.local widget.

I want to show a notification with showSimpleNotification under AppBar, so I wrap the Scaffold's body into OverlaySupport.local, but when calling showSimpleNotification from the body, the notification is showed over the AppBar.
I want to show it only over the body.

Describe the bug
I've an android app with flutter_webview_plugin (so a webapp), and if it is in foreground, every overlay widget (toast or showOverlayNotification) used doesn't show anything.
But on IOS all works perfectly.
I'm using firebase for notifications, and the onMessage event was called correctly. Inside the onMessage i would like to show the notification.

To Reproduce
Go to firebase console and send a notify to the token associated to the installed app

Expected behavior
on foreground, it should show a toast or similar widget for view the notification text

Screenshots

Version (please complete the following information):
Flutter 1.17.1 • channel stable • https://github.com/flutter/flutter.git
Framework • revision f7a6a7906b (9 weeks ago) • 2020-05-12 18:39:00 -0700
Engine • revision 6bc433c6b6
Tools • Dart 2.8.2
OverlaySupport Version: 1.0.4
Android OS: 6.0

Additional context
I've tried to show a toast in other events also, but nothing works on foreground

Currently, in its simplest form - the quickest way to show a notification at the top of the screen is via showSimpleNotification. Without resorting to writing custom notification overlay, can we extend the showSimpleNotification to include an optional parameter

bool modal=true

This way - if Notifications are tied to (say) button taps - then repeated Notifications will not be shown because the first Notification at the top of the screen being MODAL will prevent this.

in this below code i'm trying to show message when internet connection is dissconnected:

 return Consumer<ConnectivityStatus>(
   builder: (context,isOnline,_){
     if (isOnline == ConnectivityStatus.Disconnected) {
       showSimpleNotification( Text( "$isOnline" ), background: Colors.green );
     }

but i get error

Add Duration parameter to showSimpleNotification method, so that it can be a chosen value instead of a fixed duration.

I need to change the padding of showOverlayNotification, now it appears just below appBar, I want it to be below status bar.

is that possible?

How can I dismiss an OverlayNotification before showing another one?

I tried OverlaySupportEntry.of(context)?.dismiss(); before showing the notification but it doesn't show anything!

I tried to await OverlaySupportEntry.of(context)?.dismissed; but it gives an error, probably because there isn't any notification when calling it.

Is there any way to check if there's a notification showing before I call OverlaySupportEntry.of(context).dismiss(); ?

Thanks

Describe the bug
When I tried to implement your plugin in initstate or start build state then occur error like VisitChildElements() called during build.

Expected behavior
I need show Notification on start the app or screen

Version (please complete the following information):

• Flutter Version: [e.g. v2.2.3]
• OS: Android
• OverlaySupport Version : 1.2.1

how can i disable? it doesn't have any property to set that

showOverlayNotification((context) {
  return MessageNotification(
    message: messages[3],
    onReplay: () {
      OverlaySupportEntry.of(context).dismiss();
      toast('you checked this message');
    },
  );
}, duration: Duration(hours: 10));

maybe background need increase opacity

When showing from the top, it would be nice if the user could swipe up to dismiss

hello,

wonderful package and thank you.

Can you tell me please how i can dismiss the notification as soon as i press on it? I'm using the complex notification, not the simple one.

showOverlayNotification

Thanks.

Thank you for such a fantastic package. I spot an exception:

Hi,
I use RestartWidget or PhoenixWidget with MaterialApp. I try to implement overlaysupport.global by following your guide and after that my restart function not work anymore.
Env:

• Flutter channel master
• overlay_support: 1.2.1

Please help!

When textfield is focused and keyboard is open overlay is not visible when called

I am using the simple notification widget to present push notifications while the app is open. naturally, I do not want to present simple notifications notifying the user that they have a new chat message if the current active screen is displaying that chat message.

Because the simple notification function is a global function housed in the main.dart file outside of the material app widget, I have no access to context. How do I determine the current page before firing the simple notification?

现在固定为2秒后自动消失，可以让用户自己规定。

I receive that message:

../../../.pub-cache/hosted/pub.dartlang.org/overlay_support-1.0.5/lib/src/overlay.dart:156:19: Error: The method 'ancestorWidgetOfExactType' isn't defined for the class 'BuildContext'.

Version (please complete the following information):

• Flutter Version: last version
• OS: [Android]

Is it possible to dismiss notifications without using context? I can show the notification just fine without context but i'm unsure how to dismiss it without context, is this possible?

Here is my code but as you can see its requiring context which at the point of calling this i don't have:

`showSimpleNotification(
Text("this is a message from simple notification"),
background: Colors.green,
autoDismiss: false,
trailing: FlatButton(onPressed: (){

        OverlaySupportEntry.of(context).dismiss();
      }, child: Text('dismiss')))`

when combining overlay_support with packages like Firebase messaging to handle in app notifications you can run into the situation where you have a listener somewhere outside the widget tree, and you want to show a notification every time the listener fires. example:

_firebaseMessaging.configure(
    onBackgroundMessage: myBackgroundMessageHandler,
    onMessage: (Map<String, dynamic> message) async {
      myBackgroundMessageHandler(message);
    },
    onResume: (Map<String, dynamic> message) async {
      handleNotification(message, navigatorKey);
    },
    onLaunch: (Map<String, dynamic> message) async {
      handleNotification(message, navigatorKey);
    },
  );


Future<dynamic> myBackgroundMessageHandler(Map<String, dynamic> message) async {
  print('background message received');
  Map<String, dynamic> data = Map<String, dynamic>.from(message['data'] ?? message);

  if (data['type'] == 'chat') {
    if (user.isOnChatPage != data['id']) {
      print('popup');
      DocumentSnapshot chatRef = await db.collection('Chats').document(data['id']).get();
      showOverlayNotification(
        (BuildContext context) {
          return ChatNotification(
            document: chatRef,
          );
        },
        duration: Duration(milliseconds: 4000),
      );
    }
  }
}

in this case you get the error:
overlay not avaliable, dispose this call : null

Please provide an example to set toastTheme attribute when creating OverlaySupport...

Regards
