您可以使用FloatingActionButton.extended一次在 FAB 中显示文本和图标。

FloatingActionButton.extended(
  onPressed: () {
    // when clicked on floating action button prompt to create user
    Navigator.pushReplacement(
      context,
      MaterialPageRoute(
        builder: (BuildContext context) => CreateUser(),
      ),
    );
  },
  label: Text('Label'),
  icon: Icon(Icons.add),
),
