我想在IconButton的标题下面有一个AppBar。我试过了,但我有问题,中心的所有项目在那里和溢出的底部。
我的代码:

appBar: new AppBar(
    title: Column(
        children: <Widget>[
            new Text('App Title'),
            IconButton(
                icon: new Icon(new IconData(0xe902, fontFamily: 'Ionicons')),
                onPressed: () {},
            )
        ],
    ),
    centerTitle: true,
    actions: <Widget>[
        IconButton(
            icon: new Icon(new IconData(0xe906, fontFamily: 'Ionicons')),
            onPressed: () {},
        )
    ],
),

It should looks like this.

最佳答案

你可以试试这个

appBar: AppBar(
  centerTitle: true,
  title: Column(
    mainAxisAlignment: MainAxisAlignment.center,
    children: <Widget>[
      Text("App Title"),
      GestureDetector(
        child: Icon(Icons.keyboard_arrow_down),
        onTap: () {
          // handle your click here
        },
      )
    ],
  ),
),
