Description

My asset is a game written in JS. Error does not appear on Android 11 (API 30). Version 4.0.0+4 works fine on both Android versions.

When i run this code:

import 'package:flutter_inappwebview/flutter_inappwebview.dart';

class MyInAppBrowser extends InAppBrowser {
  MyInAppBrowser();

  @override
  Future onLoadStop(Uri url) async {
    print('\n\nStopped $url\n\n');
  }

  @override
  Future<NavigationActionPolicy> shouldOverrideUrlLoading(
      NavigationAction navigationAction) async {
    print('\n\n override ${navigationAction.request.url}\n\n');
    this.webViewController.loadUrl(urlRequest: navigationAction.request);
    return NavigationActionPolicy.ALLOW;
  }

  @override
  void onLoadResource(final LoadedResource resource) {
    print('Started at: ' +
        resource.startTime.toString() +
        'ms ---> duration: ' +
        resource.duration.toString() +
        'ms ' +
        resource.url.toString());
  }

  @override
  void onExit() {
    print('Exit was called in inappbrowser!');
    super.onExit();
  }

  @override
  void onConsoleMessage(final ConsoleMessage consoleMessage) {
    print('''
    console output:
      message: ${consoleMessage.message}
      messageLevel: ${consoleMessage.messageLevel}
    ''');
  }
}

import 'package:employee_app/webview/MyInappBrowser.dart';
import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';

class GameScreen extends StatefulWidget {
  static const String ROUTE_NAME = '/game';

  @override
  State<StatefulWidget> createState() => GameScreenState();
}

class GameScreenState extends State<GameScreen> {
  final MyInAppBrowser inAppBrowser = MyInAppBrowser();

  @override
  void initState() {
    super.initState();
    inAppBrowser.webViewController.addJavaScriptHandler(
      handlerName: 'gameQuit',
      callback: (arguments) => _gameQuit(arguments.first),
    );
  }

  @override
  Widget build(BuildContext context) {
    inAppBrowser.openFile(
      assetFilePath: 'assets/games-content/jetpack-blast/index.html',
      options: InAppBrowserClassOptions(
        android: AndroidInAppBrowserOptions(hideTitleBar: true),
        crossPlatform: InAppBrowserOptions(
          hideToolbarTop: true,
          hideUrlBar: true,
        ),
        inAppWebViewGroupOptions: InAppWebViewGroupOptions(
          crossPlatform: InAppWebViewOptions(
            useOnLoadResource: true,
            mediaPlaybackRequiresUserGesture: false,
          ),
          android: AndroidInAppWebViewOptions(
            databaseEnabled: true,
            domStorageEnabled: true,
          ),
        ),
      ),
    );

    return WillPopScope(
      child: Scaffold(
        body: Center(
          child: CircularProgressIndicator(),
        ),
      ),
      onWillPop: () async {
        if (inAppBrowser.isOpened()) {
          await inAppBrowser.close();
        }
        return;
      },
    );
  }
  
  _gameQuit(final int score) {}
}

It will be fixed with next release! Thanks for reporting this issue!

[pichillilorenzo]

The fix is available in the master branch now.
However, today I think I can publish the new version 5.2.1.
