我有一个AppBarComponent来显示我的应用的应用栏。

class AppBarComponent {
  static Widget titleWithImage(String title) {
    return Row(
      children: <Widget>[
        Image.asset(
          'logo.png',
          fit: BoxFit.contain,
          width: 40,
        ),
        Padding(
          padding: const EdgeInsets.symmetric(horizontal: 10.0),
          child: Text('title'),
        ),
        Row(
          children: [
            Text(
              'subtitle',
            ),
          ],
        ),
      ],
    );
  }
}

结果是这样的:

但我想要的是在appbar的右边显示副标题。

哦!我已经用

Expanded(
      child: Text(
        'subtitle',
        textAlign: TextAlign.end,
      ),
    ),

而不是用Row Package 它。

不建议使用Widget函数,而是使用Stateful/Stateless小部件,因此您可以像这样实现它...

class AppBarComponent extends StatelessWidget {

  const AppBarComponent({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return AppBar(
      leading: const Icon(Icons.circle), //TODO replace with your logo
      title: const Text('Title'),
      actions: const <Widget>[
        Text('Subtitle'),
      ],
    );
  }
}
