如何向AppBar添加图标

您可以通过将IconButton小部件添加到AppBar的actions列表中来向AppBar添加图标.

You can add an icon to the AppBar by adding an IconButton widget to the actions list of the AppBar.

AppBar(
  title: Text('My App'),
  actions: <Widget>[
    IconButton(
      icon: Icon(
        Icons.settings,
        color: Colors.white,
      ),
      onPressed: () {
        // do something
      },
    )
  ],
),
