But in my webview after clicking that button it shows this error with all external app

Can you solve this

Solution

use this and replace tel,mailto: and whatsapp with your external app links starting string.

` final flutterWebviewPlugin = new FlutterWebviewPlugin();

flutterWebviewPlugin.onUrlChanged.listen((String url) {
  if (url.startsWith('mailto:'))
  {

    _launchURL(url);
    flutterWebviewPlugin.stopLoading();
    flutterWebviewPlugin.reload();



  }
  else if (url.startsWith('tel:'))
  {

    _launchURL(url);
    flutterWebviewPlugin.stopLoading();
    flutterWebviewPlugin.reload();


  }else if (url.startsWith('whatsapp:') ||url.startsWith ('api.'))
  {

    _launchURL(url);
    flutterWebviewPlugin.stopLoading();
    flutterWebviewPlugin.reload();


  }`
