Flutter: How to attach a FloatingActionButton to the AppBar?

Question

The Scaffold-Widget only allows to place a FloatingActionButton at the bottom right or the bottom center. How can I place it between AppBar and body like here?

Answer 1

It is now possible using:

Scaffold(
      appBar: AppBar(title: Text('Title'),),
      body: ...,
      floatingActionButtonLocation: FloatingActionButtonLocation.endTop,
      floatingActionButton: FloatingActionButton(...),
    ),
