Getting below error in console panel:

The plugins `flutter_windowmanager` use a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if these plugins support the Android V2 embedding. Otherwise, consider removing them since a future release of Flutter will remove these deprecated APIs.

Need to update flutter_windowmanager plugin as per latest flutter version. Thanks.

I am using flutter_pdfview package I found a black screen with it in oppo devices only , in all other devices it works perfectly.

dependencies: flutter_pdfview: ^1.0.4 flutter_windowmanager: ^0.0.2

Function which called in main() to apply on the whole app Future secure() async { await FlutterWindowManager.addFlags(FlutterWindowManager.FLAG_SECURE); }

This is my flutter doctor -v

I added this plugin in the specific screen of my app where I want to disable the screenshot. But my whole app gets disable t get the screenshot. I added the in the below way, don't where i am getting wrong.

Added the Code:

pubspec.yaml flutter_windowmanager: ^0.0.2

class PreventScreenShot extends StatefulWidget {
  PreventScreenShot({Key key}) : super(key: key);

  @override
  _PreventScreenShotState createState() => _PreventScreenShotState();
}

class _PreventScreenShotState extends State<PreventScreenShot> {

  Future _flagSecure() async {
    await FlutterWindowManager.addFlags(FlutterWindowManager.FLAG_SECURE);
  }

  Future _clearFlags() async {
    await FlutterWindowManager.clearFlags(FlutterWindowManager.FLAG_SECURE);
  }

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

  @override
  void dispose() {
    // TODO: implement dispose
    super.dispose();
    _clearFlags();
  }


  @override
  Widget build(BuildContext context) {
    return Scaffold(
          body: Center(
         child: Text("Testing"),
      ),
    );
  }
}

So I started using this package around last week, and it works fine: screenshot is blocked, and the screen turned black when screen recording. However, today I tried it again and my app's screen no longer turns black when being recorded. The only difference I had in my phone is that it was updated to Android 11, even though I'm not sure if that's the case. Anyone else have the same issue? The device I use is Samsung Galaxy S10.

await FlutterWindowManager.addFlags(FlutterWindowManager.FLAG_SECURE);

not able to prevent screen video recorder using this..(tested using DU Recorder)

I want to prevent user to resize app, my main code like this :

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  if (Platform.isWindows) {
    await WindowManager.instance.ensureInitialized();
    windowManager.waitUntilReadyToShow().then((_) async {
      await windowManager.setTitleBarStyle(
        TitleBarStyle.hidden,
        windowButtonVisibility: false,
      );
      await windowManager.setSize(const Size(755, 545));
      await windowManager.setMinimumSize(const Size(755, 545));
      await windowManager.setPreventClose(true);
      await windowManager.setSkipTaskbar(false);
      await windowManager.setResizable(false);
      await windowManager.setMinimizable(true);
      await windowManager.center();
      await windowManager.focus();
      await windowManager.show();
    });
  }
...

And my home page is wrapped within "DragToMoveArea". But the app can still be maximized by double clicking any area of the page.

Migrate to flutter embedding v2. fixes #17

• https://flutter.dev/docs/development/packages-and-plugins/plugin-api-migration
• https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects

It looks like there was an attempt in https://github.com/adaptant-labs/flutter_windowmanager/commit/0a3e2cad3c122e5b12f16d82b3f0c3a97cbeb4d0 but this only touched on the example app, not the plugin. and the only thing related to v2 embedding was the introduction of the meta-data in the AndroidManifest.xml, nothing else.

With the latest flutter (dev) channel the following warning is shown. I guess it would be time to migrate to the new embedding apis. If this project is still maintained i can try to create a PR?

The plugin `flutter_windowmanager` uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding.
Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding:
https://flutter.dev/go/android-plugin-migration.

I was using this package in an app I'm just porting to Flutter 2.2. I'm not used to write plugins nor MethodChannels, but thanks to the unit tests I believe I added support to null safety in this package.

I'd like to propose this fix for evaluation and merge it, if that is useful.

Flutter 3.0.5 Tools • Dart 2.17.6 • DevTools 2.12.2

[ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: MissingPluginException(No implementation found for method addFlags on channel flutter_windowmanager)

The return type of the FlutterWindowManager.addFlags(FlutterWindowManager.FLAG_SECURE) function is Future<bool>, which is just bubbling up the value from the method channel. This is great on Android, but on iOS, the method channel returns a string of the iOS version from boilerplate plugin code. At runtime, if the addFlags function is invoked in iOS, an exception is thrown because of invalid type coercion.

The obvious workaround is to only invoke the function if Flutter detects Platform.isAndroid, but this is not intuitive nor represented in documentation.

I suggest modifying the iOS plugin code to invoke the result function with value false.
