[Bug]: [share_plus][web][iOS] ShareXFiles doesn't work after first call

[novikov-studio]

Platform

iOS 15,0

Plugin

share_plus

Version

6.2.0

Flutter SDK

3.3.8

Steps to reproduce

1. Open Example project in Android Studio on MacOS
2. Add Additional run args
   --web-port=80 --web-hostname=0.0.0.0 --web-launch-url=http://localhost --web-renderer=canvaskit
3. Run
4. Open iOS Simulator (for me: iPhone 11 Pro & iOS15.0)
5. Launch Safari in simulator and navigate to http://localhost
6. Press "Share XFile from Assets" button
7. In Share dialog choose "Save Image"
8. Press "Share XFile from Assets" button again - no reaction

In console you can see "Unhandled Promise Rejection".

If you wrap Share.shareXFiles in try catch, you can see exception: "NotAllowedError: The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission".

It seems like first call does not return.

Code Sample

// See Example - _onShareXFileFromAsset() or my version
//
Future<void> _share() async {
  final buffer = await rootBundle.load('assets/test.jpg');

  final data = Uint8List.view(buffer.buffer);
  try {
    final file = XFile.fromData(
      data,
      mimeType: 'image/jpeg',
      name: 'test.jpg',
      lastModified: DateTime.now(),
      length: data.length,
    );

    final result = await Share.shareXFiles([file]);

    debugPrint('${result.status}');
  } on Object catch (e) {
    debugPrint('$e');
  }
}

@novikov-studio have you found any solution or workaround yet
I'm also facing the same issue on the web of iOS. If you can tell me that would be really helpful for us.

@vbuberen can you tell us please if this issue is resolved or not?

[novikov-studio]

@ergarvitrai, no, I moved from PWA to iOS app.
