颤振:热装载和路线

hot-reload flutter dart routes

footurist · 技术社区 · 7 年前

我注意到当我扩展MaterialPageRoutes,然后像这样引用它们时

class Route extends MaterialPageRoute {
  Route(): super(
    builder: (context) {
      return SomeWidget();
    }
  );
}
...somewhere in the build method of another class...
Navigator.push(context, Route())

热重新加载不会像我那样重建路由的内容

...somewhere in the build method of another class...
Navigator.push(context, MaterialPageRoute(
  builder: (context) {
    return SomeWidget();
  }
))

class Route extends MaterialPageRoute {
  Route(): super(
    builder: (context) {
      return RouteWidget();
    }
  );
}
class RouteWidget extends StatelessWidget {
  Widget build(BuildContext context) {
    return SomeWidget();
  }
}
...somewhere in the build method of another class...
Navigator.push(context, Route())

我觉得特别奇怪的是,最后的解决办法奏效了。知道我错过了什么吗?文档显示热重新加载将重建所有小部件。
