In Flutter, I use the flutter webview plugin to launch a url like:
flutterWebviewPlugin.launch(url)
or
WebviewScaffold(
url:
Looks like you can achieve what you need using this plugin : https://pub.dartlang.org/packages/flutter_web_view
Listen for your redirects:
flutterWebView.listenForRedirect("fb://profile", true);
Get the value using :
flutterWebView.onRedirect.listen((url) {
flutterWebView.dismiss();
//now you have the url
});
After you have the url you can use this package https://pub.dartlang.org/packages/url_launcher
