• I have searched the existing issues

Package

youtube_player_iframe (Default)

What happened?

I upgrade the package from youtube_player_flutter: ^8.1.2 to youtube_player_flutter: ^9.0.3

1. Fixed issue: Unknown feature SUPPRESS_ERROR_PAGE with Android issue: Unknown feature SUPPRESS_ERROR_PAGE, webview not displaying at all pichillilorenzo/flutter_inappwebview#2150
2. Unresolved issue is: Unable to pop router 'package:flutter/src/widgets/navigator.dart': Failed assertion: line 5273 pos 12: '!_debugLocked': is not true. When I use Navigator.of(context).pop() on a view with YoutubePlayer.

Thank you in advance

What is the expected behaviour?

Navigator close correctly

How to reproduce?

WidgetsBinding.instance.addPostFrameCallback((_) {
  final router = GoRouter.of(context); // or Navigator.of(context)
  if (router.canPop()) {
    try {
      router.pop();
    } catch (e) {
      Logger('AppMainBar').severe('Unable to pop router $e');
    }
  } else {
    router.goNamed(HomePage.name);
  }
});

[amankachhal99]

facing the same issue. Request to help to fix this as soon as possible. It's becoming a blocker for the video screen in the app.

Same issue here. It was working fine until I upgrade to flutter 3.24.3 (from 3.24.0). Using package youtube_player_flutter (9.0.3).

Exception originates at this call to Navigator.pop() at youtube_player_builder.dart line 77:

  Widget build(BuildContext context) {
    final player = Container(
      key: playerKey,
      child: PopScope(
        canPop: false,
        onPopInvoked: (didPop) {
          final controller = widget.player.controller;
          if (controller.value.isFullScreen) {
            widget.player.controller.toggleFullScreenMode();
          } else {
            Navigator.pop(context);      // <== HERE
          }
        },
        child: widget.player,
      ),
    );
    final child = widget.builder(context, player);

    return OrientationBuilder(
      builder: (context, orientation) {
        return orientation == Orientation.portrait ? child : player;
      },
    );
  }
