flutter - 如何显示关于对话框？

Question

您好，我看到了 flutter 团队的视频 https://www.youtube.com/watch?v=YFCSODyFxbE&t=0s当尝试添加 aboutdialog 时。名称下显示错误。有人尝试这个小部件吗？

调用此方法来查看对话框。

void _showDialog() {
  showAboutDialog(
    context: context,
    applicationName: 'Flutter',
    applicationIcon: FlutterLogo(),
    applicationVersion: '1.0.0',
    children: [
      Text('This is an About Dialog in Flutter'),
    ]
  );
}
