Flutter Material“点击更新”按钮

Question

Is there an 'out of the box' implementation of the functionality you get in the google app/etc. where the button at the bottom appears that allows you to 'Tap to update'? A custom snack bar doesn't seem viable as you have to have the title as well as the onTap action.

Answer 1

Try Using Floating Action Button

floatingActionButtonLocation: FloatingActionButtonLocation.centerFloat,
floatingActionButton: ClipRRect(
  borderRadius: BorderRadius.circular(20),
  child: Container(
    height: 40,
    child: RaisedButton(
      color: Colors.blue,
      onPressed: () => {},
      child: Text('Tap to Update'),
    ),
  ),
),

Answer 2

try this combination

Scaffold(
    bottomNavigationBar: FlatButton(
      child: Text('Flat Button'),
      onPressed: () {},
    ),
    floatingActionButtonLocation:
        FloatingActionButtonLocation.centerFloat,
    floatingActionButton: RaisedButton(
      child: Text('Floating Button'),
      onPressed: () {},
    ),
);
