Yes, I've tried |

I just tested on Android 9 (real device) and Android 10 (simulator) and it works fine! import 'dart:async';

Future main() async {
WidgetsFlutterBinding.ensureInitialized();
runApp(new MyApp());
}

@override
_MyAppState createState() => new _MyAppState();

class _MyAppState extends State<MyApp> {
InAppWebViewController webView;
String url = "";
double progress = 0;
@override
void initState() {
super.initState();
}
@override
void dispose() {
super.dispose();
}
@override

@RomanKapshuk Mmm ok. So, let's try this: Use flutter_inappwebview:
git:
url: https://github.com/pichillilorenzo/flutter_inappwebview.git
ref: masterThen, launch my code example again and post here the FULL logs (from start to the end) that you are receiving in Android Studio @Phearun99, if you want, you can also help us to test it! Thanks! |
