This is how it will look when you add actions to the Appbar.
Here is the code that you need to add to your AppBar Class.
AppBar(
title: Text(widget.title),
actions: <Widget>[
IconButton(
icon: Icon(Icons.search),
tooltip: 'Search',
onPressed: null,
),
IconButton(
icon: Icon(Icons.message),
tooltip: 'Message',
onPressed: null,
),
IconButton(
icon: Icon(Icons.more_vert),
tooltip: 'Menu',
onPressed: null,
),
],
),
Thanks. Hope this will be helpful.
