Is it possible to register a Flutter app as an Android Intent Filter and to handle Incoming Intents? : <p>One can launch another Activity using an Intent from a Flutter app: 
<a href="https://github.com/flutter/flutter/blob/master/examples/widgets/launch_url.dart">https://github.com/flutter/flutter/blob/master/examples/widgets/launch_url.dart</a></p>

<pre><code>import 'package:flutter/widgets.dart';
import 'package:flutter/services.dart';

void main() {
  runApp(new GestureDetector(
    onTap: () {
      Intent intent = new Intent()
        ..action = 'android.intent.action.VIEW'
        ..url = 'http://flutter.io/';
      activity.startActivity(intent);
    },
    child: new Container(
      decoration: const BoxDecoration(
        backgroundColor: const Color(0xFF006600)
      ),
      child: new Center(
        child: new Text('Tap to launch a URL!')
      )
    )
  ));
}
</code></pre>

<p>But can one do the following with the Flutter Activity Intent services when an Intent is passed to the app?

<pre><code>. . .
void onCreate (Bundle savedInstanceState) {
    ...
    // Get intent, action and MIME type
    Intent intent = getIntent();
. . .
</code></pre>
