I trying to fetch the response from the website, for that im using flutter_inappwebview: ^6.0.0-beta.25 . in the web side I added Javascript code. but I didn't get response in the flutter app. If I call window.flutter_inappwebview.callHandler('FlutterFunction', "got success message"); without window.addEventListener I got this error "Cannot read properties of undefined (reading 'callHandler')". Please help me to fix this.
class MyApp extends StatefulWidget {
const MyApp({Key? key}) : super(key: key);
@override
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
final GlobalKey webViewKey = GlobalKey();
InAppWebViewController? webViewController;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: const Text("InAppWebView test")),
body: Column(children: <Widget>[
Expanded(
child: InAppWebView(
key: webViewKey,
initialUrlRequest: URLRequest(url: WebUri("https://mfkk16.github.io/kkmf-resume/")),
onWebViewCreated: (controller) {
webViewController = controller;
controller.addJavaScriptHandler(
handlerName: 'FlutterFunction',
callback: (arguments) {
ScaffoldMessenger.of(context).showSnackBar(SnackBar(
content: Text(arguments[0]),
duration: const Duration(seconds: 1),
));
});
},
),
),
]));
}
}
