Flutter局部跳转

flutter局部跳转的思路其实很简单,只需要在一个控件外创建一个根路由,仿照安卓的命名,我给这个路由起名叫Fragment

class Fragment extends StatelessWidget {
  final Widget child;
  final String root;

  const Fragment({required this.child, this.root = "/", super.key});

  @override
  Widget build(BuildContext context) {
    return Navigator(
      initialRoute: root,
      onGenerateRoute: (RouteSettings settings) {
        WidgetBuilder builder;
        builder = (context) => child;
        return MaterialPageRoute(builder: builder);
      },
    );
  }
}
