unknown_url_scheme

[Trend74X]

Description

I want to redirect to dialpad with given number when I click on telephone icon/ somewhere. My webview code is coded in angular and it redirects into dialpad when it runs in chrome, but shows error while running in inappwebview. I dont think its already implemented in inappwebview .

Issue it shows is net::ERR_UNKNOWN_URL_SCHEME

That's the expected behavior. You need to implement it by yourself. People may get confused thinking that a WebView is a Browser (such as Chrome, Firefox, Safari, etc.). It is not.

To achieve what you need, you need to use the shouldOverrideUrlLoading event (to be able to listen this event, you need to enable the useShouldOverrideUrlLoading webview option). Also, you can use the url_launcher plugin to open the dialpad. Here is an example:

shouldOverrideUrlLoading: (controller, navigationAction) async {
  var uri = navigationAction.request.url!;

  if (uri.scheme == 'tel') {
    if (await canLaunch(url)) {
      // Launch the App
      await launch(
        url,
      );
      // and cancel the request
      return NavigationActionPolicy.CANCEL;
    }
  }

  return NavigationActionPolicy.ALLOW;
},
