How to handle Time Out

[rodrigoavalente]

Hello, I'm trying to do something with the webview if a time out error occurs, however, the event is not triggered when the time out happens on my device.

StreamSubscription _onDestroy;
StreamSubscription<String> _onUrlChanged;
StreamSubscription<WebViewStateChanged> _onStateChanged;  StreamSubscription<WebViewHttpError> _onHttpError;

...
@override
void initState() {
    super.initState();

    ...
   _onHttpError = _flutterWebviewPlugin.onHttpError.listen((WebViewHttpError error) {
       // TODO: implement
       print(error.code);
   });
}

@rodrigoavalente did you solve the problem yet?

@scofield-hello unfortunally I don't. I'm trying to use some gimmicks to check if connection is available and send the user to another view with some message, but it is not perfect.

Hello, sorry for the late reply, I had to stop working on the app that was using this plugin, and I just had returned to working on it, from my investigations I found that the Connection Refused and Connection Timeout errors are returning -6 and -8 on android and as the class WebViewHttpError expects two strings as parameters an exception is thrown and nothing happens, so the event is not fired.

// base.dart file function that handles the events
 Future<Null> _handleMessages(MethodCall call) async {
    switch (call.method) {
      case 'onBack':
        _onBack.add(null);
        break;
      case 'onDestroy':
        _onDestroy.add(null);
        break;
      case 'onUrlChanged':
        _onUrlChanged.add(call.arguments['url']);
        break;
      case 'onScrollXChanged':
        _onScrollXChanged.add(call.arguments['xDirection']);
        break;
      case 'onScrollYChanged':
        _onScrollYChanged.add(call.arguments['yDirection']);
        break;
      case "onProgressChanged":
        _onProgressChanged.add(call.arguments["progress"]);
        break;
      case 'onState':
        _onStateChanged.add(
          WebViewStateChanged.fromMap(
            Map<String, dynamic>.from(call.arguments),
          ),
        );
        break;
      case 'onHttpError':
        _onHttpError.add(WebViewHttpError(call.arguments['code'], call.arguments['url']));
        break;
    }
  }

// base.dart file WebViewHttpError
class WebViewHttpError {
  WebViewHttpError(this.code, this.url);

  final String url;
  final String code;
}

Well, I don't know if the returning codes are the expected on android, I would appreciate if someone could provide some advice on this, thanks for the help.

I'll close this, I've noticed that problem was fixed on 0.3.6.
