title: Flutter: Is it somehow possible to create App Widgets (Android) and Today Extensions (iOS)?
body: <p>I took a look at flutter for building a mobile app. Is it possible to create <code>Widgets</code> (not flutter-widgets, but <code>App Widgets</code> (Android) and <code>Today Extensions</code> (iOS)) in a flutter app? I guess it can't be done with dart, but is there a way of implementing them native in Java/Swift and include them in the flutter-app?</p>
  
  <p>Thanks!</p>
