最简单的方法是（假设你的家是一个以/为名称的命名路由）：
Navigator.popUntil(context, ModalRoute.withName('/'));
下面是我如何回到主页并清空堆栈的示例。它在断开连接时也很有用。
class MyWidget extends StatelessWidget {
@override
Widget build(BuildContext context) {
return TextButton(
child: const Text('Log out'), // Go to the HomePage
onPressed:(){
// if you use named routes
Navigator.of(context).pushAndRemoveUntil<void>(
"/route/to/homepage", (route) => false,
);
// if you don't use named routes
Navigator.of(context).popUntil((route) => route.isFirst);
}
);
}
}
