Demo

1. Clip of example app and 2. Working of button click in the background

Application Class

JAVA (Application.java)

  import android.os.Bundle;
  import in.jvapps.system_alert_window.SystemAlertWindowPlugin;
  import io.flutter.app.FlutterApplication;
  import io.flutter.plugin.common.PluginRegistry;
  import io.flutter.plugins.GeneratedPluginRegistrant;

  public class Application extends FlutterApplication implements PluginRegistry.PluginRegistrantCallback {

      @Override
      public void onCreate() {
          super.onCreate();
          //This is required as we are using background channel for dispatching click events
          SystemAlertWindowPlugin.setPluginRegistrant(this);
      }

      @Override
      public void registerWith(PluginRegistry pluginRegistry) {
          GeneratedPluginRegistrant.registerWith(pluginRegistry);
      }

  }

KOTLIN (Application.kt)

  import `in`.jvapps.system_alert_window.SystemAlertWindowPlugin
  import io.flutter.app.FlutterApplication
  import io.flutter.plugin.common.PluginRegistry
  import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback
  class Application : FlutterApplication(), PluginRegistrantCallback {
      override fun onCreate() {
          super.onCreate()
          SystemAlertWindowPlugin.setPluginRegistrant(this)
      }

     override fun registerWith(registry: PluginRegistry) {
        SystemAlertWindowPlugin.registerWith(registry.registrarFor("in.jvapps.system_alert_window"));
     }
  }

Manifest

  //Permissions

Android 10 & below, Android GO (API 27)

Uses 'draw on top' permission and displays it as a overlay window

Android 11 & above

User has to allow 'All conversations can bubble' in the notification settings of the app. Uses Android Bubble APIs to show the overlay window inside a notification bubble.

Android GO (API 29)

User has to manually enable bubbles from the developer options. Uses Android Bubble APIs to show the overlay window inside a notification bubble.

IOS

Displays as a notification in the notification center [Help Needed]

Example

Request overlay permission

  await SystemAlertWindow.requestPermissions;

Show the overlay

                  text: SystemWindowText(text: "Some body", fontSize: 12, textColor: Colors.black45),
                ),
              ],
              gravity: ContentGravity.CENTER,
            ),
          ],
          padding: SystemWindowPadding(left: 16, right: 16, bottom: 12, top: 12),

      notificationTitle: "Incoming Call",
      notificationBody: "+1 646 980 4741",
      prefMode: SystemWindowPrefMode.DEFAULT);
      //Using SystemWindowPrefMode.DEFAULT uses Overlay window till Android 10 and bubble in Android 11
      //Using SystemWindowPrefMode.OVERLAY forces overlay window instead of bubble in Android 11.
      //Using SystemWindowPrefMode.BUBBLE forces Bubble instead of overlay window in Android 10 & above

Register for onClick events (button click)

  SystemAlertWindow.registerOnClickListener(callBackFunction);

  ///
  /// As this callback function is called from background, it should be declared on the parent level
  /// Whenever a button is clicked, this method will be invoked with a tag (As tag is unique for every button, it helps in identifying the button).
  /// You can check for the tag value and perform the relevant action for the button click
  ///
  void callBackFunction(String tag) {
    switch(tag){
      case "simple_button":
        print("Simple button has been clicked");
        break;
      case "focus_button":
        print("Focus button has been clicked");
        break;
      case "personal_btn":
        print("Personal button has been clicked");
        break;
      default:
        print("OnClick event of $tag");
    }
  }

Close the overlay

  SystemAlertWindow.closeSystemWindow();

Isolate communication

Use this snippet, if you want the callbacks on your main thread, instead of handling them in an isolate (like mentioned above)

Create an isolate_manager.dart

import 'dart:isolate';

import 'dart:ui';

class IsolateManager{

  static const FOREGROUND_PORT_NAME = "foreground_port";

  static SendPort lookupPortByName() {
    return IsolateNameServer.lookupPortByName(FOREGROUND_PORT_NAME);
  }

  static bool registerPortWithName(SendPort port) {
    assert(port != null, "'port' cannot be null.");
    removePortNameMapping(FOREGROUND_PORT_NAME);
    return IsolateNameServer.registerPortWithName(port, FOREGROUND_PORT_NAME);
  }

  static bool removePortNameMapping(String name) {
    assert(name != null, "'name' cannot be null.");
    return IsolateNameServer.removePortNameMapping(name);
  }

}

While initializing system alert window in your code

    await SystemAlertWindow.checkPermissions;
    ReceivePort _port = ReceivePort();
    IsolateManager.registerPortWithName(_port.sendPort);
    _port.listen((dynamic callBackData) {
      String tag= callBackData[0];
      switch (tag) {
        case "personal_btn":
          print("Personal button click : Do what ever you want here. This is inside your application scope");
          break;
        case "simple_button":
          print("Simple button click : Do what ever you want here. This is inside your application scope");
          break;
        case "focus_button":
          print("Focus button click : Do what ever you want here. This is inside your application scope");
          break;
      }
    });
    SystemAlertWindow.registerOnClickListener(callBackFunction);

Now the callBackFunction should looks like

bool callBackFunction(String tag) {
  print("Got tag " + tag);
  SendPort port = IsolateManager.lookupPortByName();
  port.send([tag]);
  return true;
}

Error when calling registerOnClickListener

I've tried multiple versions of flutter, but always get this error when calling SystemAlertWindow.registerOnClickListener(callBackFunction);:

E/flutter (22530): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: type '(MethodCall) => Null' is not a subtype of type '((MethodCall) => Future<dynamic>)?' in type cast
E/flutter (22530): #0      SystemAlertWindow.registerOnClickListener (package:system_alert_window/system_alert_window.dart:67:7)

I've been using SystemAlertWindow 0.50, and i've tried with flutter 2.2.1 and 1.22.6. Any suggestions?

Button callback is not invoked

Describe the bug Hello dear @pvsvamsi and thank you for sharing! I seem to be having trouble with buttons call back saying Error -32601 received from application: Method not found Here is some usefull info:

To Reproduce Steps to reproduce the behavior (use the code below):

import 'dart:async';

import 'package:flutter/material.dart';
import 'package:get/get.dart';
import 'package:inspirationwall/ui/views/home/home_view.dart';
import 'package:flutter/services.dart';
import 'package:system_alert_window/system_alert_window.dart';

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

class MyApp extends StatefulWidget {
  // This widget is the root of your application.
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';
  bool _isShowingWindow = false;

  @override
  void initState() {
    super.initState();
    _initPlatformState();
    _checkPermissions();
    SystemAlertWindow.registerOnClickListener(callBack);
    showAlertDialog();
  }

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> _initPlatformState() async {
    String platformVersion;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      platformVersion = await SystemAlertWindow.platformVersion;
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;
    });
  }

  Future<void> _checkPermissions() async {
    await SystemAlertWindow.checkPermissions;
  }

  showAlertDialog() {
    print("test");
    Timer(
      Duration(seconds: 5),
      () {
        _showOverlayWindow();
      },
    );
  }

  void _showOverlayWindow() {
    if (!_isShowingWindow) {
      SystemWindowHeader header = SystemWindowHeader(
          title: SystemWindowText(
              text: "Incoming Call", fontSize: 10, textColor: Colors.black45),
          padding: SystemWindowPadding.setSymmetricPadding(12, 12),
          subTitle: SystemWindowText(
              text: "9898989899",
              fontSize: 14,
              fontWeight: FontWeight.BOLD,
              textColor: Colors.black87),
          decoration: SystemWindowDecoration(startColor: Colors.grey[100]),
          button: SystemWindowButton(
              text: SystemWindowText(
                  text: "Personal", fontSize: 10, textColor: Colors.black45),
              tag: "personal_btn"),
          buttonPosition: ButtonPosition.TRAILING);
      SystemAlertWindow.showSystemWindow(
          height: 100,
          header: header,
          margin: SystemWindowMargin(left: 20, right: 20, top: 200, bottom: 0),
          gravity: SystemWindowGravity.TOP);
      setState(() {
        _isShowingWindow = true;
      });
    } else {
      setState(() {
        _isShowingWindow = false;
      });
      SystemAlertWindow.closeSystemWindow();
    }
  }

  @override
  Widget build(BuildContext context) {
    // TODO: implement build
    return GetMaterialApp(
      title: 'Inspiration Wall',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomeView(),
    );
  }
}

void callBack(String tag) {
  print(tag);
  switch (tag) {
    case "simple_button":
    case "updated_simple_button":
      SystemAlertWindow.closeSystemWindow();
      break;
    case "focus_button":
      SystemAlertWindow.closeSystemWindow();

      print("Focus button has been called");
      break;
    case "personal_btn":
      SystemAlertWindow.closeSystemWindow();
      break;
    default:
      print("OnClick event of $tag");
  }
}

Expected behavior I would expect to run the code inside case "focus_button": SystemAlertWindow.closeSystemWindow(); in this case when the button is tapped.

Screenshots If applicable, add screenshots to help explain your problem.

Versions (please complete the following information):

SystemAlertWindow: 0.2.2+2
Device: Xiaomi Mi9
OS: Android 10

Additional context I have placed the callBack method outside of my main class as you described in the readme but it still seems to be unable to find it. The callback is placed inside main.dart file as is the rest of the code.

EDIT: I do get the following in the console: I/SystemAlertWindowPlugin(15951): Unable to start callBackHandle... as plugin is not registered

Is this related to :

public class Application extends FlutterApplication implements 
PluginRegistry.PluginRegistrantCallback {

      @Override
      public void onCreate() {
          super.onCreate();
          //This is required as we are using background channel for dispatching click events
          SystemAlertWindowPlugin.setPluginRegistrant(this);
      }

      @Override
      public void registerWith(PluginRegistry pluginRegistry) {
          GeneratedPluginRegistrant.registerWith(pluginRegistry);
      }

  }

Do i have to put this somewhere? Sorry i'm a bit newbie with all this!

main/java/io.flutter.plugins/GeneratedPluginRegistrant:

@Keep
public final class GeneratedPluginRegistrant {
  public static void registerWith(@NonNull FlutterEngine FlutterEngine) {
    ShimPluginRegistry shimPluginRegistry = new ShimPluginRegistry(flutterEngine);
      in.jvapps.system_alert_window.SystemAlertWindowPlugin.registerWith(shimPluginRegistry.registrarFor("in.jvapps.system_alert_window.SystemAlertWindowPlugin"));
  }
}

EDIT: Tried with newly created application and its the same error. I think it has something to do with:

        </activity>
        <!-- Don't delete the meta-data below.
             This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />

closeSystemWindow is not working properly

After calling showSystemWindow in android 11, with prefMode=SystemWindowPrefMode.OVERLAY, it displays correctly the expected screen, but after clicking a button to close the screen and calling closeSystemWindow, the window doesn't close. And I'm getting this message from the console: [ ] I/SystemAlertWindowPlugin( 6688): Invoke call back success, so it's supposed to be working fine, but it doesn't.

This system window even remains in front of my screen and I can't get rid of it, it's displaying always and I have to restart my phone in order for it to dissapear.

I'm using version 0.4.3 of SystemAlertWindow and android 11. I'm not testing it in iOS because this app is only for android.

This is the code I'm using to show the alert window:

return await SystemAlertWindow.showSystemWindow( header: SystemWindowHeader(...), body: SystemWindowBody(...), footer: SystemWindowFooter(...), width: 400, prefMode: SystemWindowPrefMode.OVERLAY, margin: SystemWindowMargin(left: 0, right: 0, top: 0, bottom: 0), gravity: SystemWindowGravity.CENTER);

And this is the code I'm using to try to close the alert window: SystemAlertWindow.closeSystemWindow();

How can I close the window with a button in the window?

@pvsvamsi I can't seem to close my alert window properly. I have a alert window and I want the window to be removed when pressing on the button in the window.

This code works the first time but the second time the window keeps existing even tho the remove alert window method is being called. What would be the recommended approach?

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:system_alert_window/system_alert_window.dart';

class SystemOverlayController {
  static SystemOverlayController _instance;
  String _platformVersion = 'Unknown';
  bool _isShowingWindow = false;

  static SystemOverlayController get instance {
    if(_instance == null)
      _instance = SystemOverlayController._privateConstructor();
    return _instance;
  }

  SystemOverlayController._privateConstructor();

  void initialize() async {
    try {
      _platformVersion = await SystemAlertWindow.platformVersion;
      await SystemAlertWindow.checkPermissions;
      await SystemAlertWindow.registerOnClickListener(systemOverlayOnClickListner);
    } on PlatformException {
      _platformVersion = 'Failed to get platform version.';
    }finally{
      print('initializing complete');
    }
  }

  static systemOverlayOnClickListner(String value) {
    if (value == 'button_app_to_foreground') {
      // The line below isn't outputting correctly. It will always say false. I assume this is because 
      // the callback is being ran on another thread. If I could get the correct value I could check
      // if I should close the window
      print(SystemOverlayController.instance._isShowingWindow);
      // This always gets executed at the right time but it doesn't always close the overlay
      SystemAlertWindow.closeSystemWindow();
    }
  }

  Future<void> showSimpleSystemOverlay() async {
    if(_isShowingWindow){
      await SystemAlertWindow.closeSystemWindow();
      _isShowingWindow = false;
    }

    SystemWindowHeader header = SystemWindowHeader(
      title: SystemWindowText(text: "Title", fontSize: 10, textColor: Colors.black45),
      padding: SystemWindowPadding.setSymmetricPadding(12, 12),
      subTitle:
          SystemWindowText(text: "Subtitle", fontSize: 14, fontWeight: FontWeight.BOLD, textColor: Colors.black87),
      decoration: SystemWindowDecoration(startColor: Colors.grey[100]),
    );

    SystemWindowFooter footer = SystemWindowFooter(
        buttons: [
          SystemWindowButton(
            text: SystemWindowText(text: "Go To App", fontSize: 12, textColor: Color.fromRGBO(250, 139, 97, 1)),
            tag: "button_app_to_foreground",
            padding: SystemWindowPadding(left: 10, right: 10, bottom: 10, top: 10),
            width: 0,
            height: SystemWindowButton.WRAP_CONTENT,
            decoration: SystemWindowDecoration(
                startColor: Colors.white, endColor: Colors.white, borderWidth: 0, borderRadius: 0.0),
          ),
        ],
        padding: SystemWindowPadding(left: 16, right: 16, bottom: 12),
        decoration: SystemWindowDecoration(startColor: Colors.white),
        buttonsPosition: ButtonPosition.TRAILING);

    SystemAlertWindow.showSystemWindow(
        height: 150,
        width: 230,
        header: header,
        footer: footer,
        margin: SystemWindowMargin(left: 8, right: 8, top: 0, bottom: 0),
        gravity: SystemWindowGravity.CENTER);
        
    _isShowingWindow = true;
  }
}

I am calling the showSimpleOverlay from my onBackgroundMessage() which is a method coming from the cloud messaging package, and is also ran in the background.

  static Future<dynamic> myBackgroundMessageHandler(Map<String, dynamic> message) async {
    print('on background message');
    await SystemOverlayController.instance.showSimpleSystemOverlay();
  }

I think it has something to do with the fact that I can't check if a window is open in systemOverlayOnClickListner() so I am calling it while no window is open but not sure.

Callback function is not called at all with no error

After messing around

I got the window to show - but now any button pressed is not calling the callbackfunction

In console all what I get is this

I/FLTFireMsgService( 3830): FlutterFirebaseMessagingBackgroundService started!

When i click the button i get the log of invoking callback and invoking on method as shown above

But I inserted print function before the case in the call back and even this is not giving any thing

  print('TAG RECORDER IS : $tag');
  switch (tag) {
    case "decline_button":
      print("Simple button has been clicked");

How can I send a message from the callback to the app?
@pvsvamsi How can I send a message from the callback to the app? You told me I should use the IsolateManager but I can't seem to find that class in the flutter docs. And I can't find an isolate being spawned anywhere. I more info about this would also be good to have in the SystemAlertWindow docs.

static Future<void> systemOverlayOnClickListner(String value) async { if (value == 'button_app_to_foreground') { await SystemAlertWindow.closeSystemWindow(); // how can I send a message to te main isolate here? } }

Overlay not showing in android 12

No overlay shown in A12 currently.

Error Log Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

FloatingActionButton

https://www.journaldev.com/14673/android-floating-widget

it's the main reason of the overlay widgets .., so it's the most important one, more than the truecaller window .. we need this widget with very simple action .. when we press on it just bring the app in foreground ..

i can't do this ..

and why you force the windows background color to white ? i want to control it and change it's color to transparent for example or black ..

and there's another problem .. if you make small size window , when you move it any direction , it automatically go back to the right side ..

please fix this things ,thx.
waiting for reply closed as no reply

Allow footer buttons to be arranged in a column

At the moment, when you stack footer buttons, they are arranged in a row. Also, there is no way of appending buttons to the System Alert Window.

It would be great if we could arrange the footer buttons in a column. Alternatively, you could include the buttons in the body element of the system alert window and allow us to arrange them in a column or row.
