您可以使用
onGenerateRoute属性为小部件应用程序生成路由。
这是一个非常小的实现：
import 'package:flutter/widgets.dart';void main() => runApp(new MyWidgetsApp());class MyWidgetsApp extends StatelessWidget { Route generate(RouteSettings settings){ Route page; switch(settings.name){ case "/": page = new PageRouteBuilder( pageBuilder: (BuildContext context,Animation<double> animation, Animation<double> secondaryAnimation){ return new Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ const Text("Home Page",textDirection: TextDirection.ltr,), const Padding(padding: const EdgeInsets.all(10.0)), new GestureDetector( onTap: () => Navigator.of(context).pushNamed("/first"), child: new Container(padding: const EdgeInsets.all(10.0),color:Colors.blue,child: const Text("Go to First Page"), ), ), const Padding(padding: const EdgeInsets.all(10.0)), new GestureDetector( onTap: () => Navigator.of(context).pushNamed("/abcd"), child: new Container(padding: const EdgeInsets.all(10.0),color:Colors.blue,child: const Text("Unkown Route"), ), ) ], ); }, transitionsBuilder: (_, Animation<double> animation, Animation<double> second, Widget child) { return new FadeTransition( opacity: animation, child: new FadeTransition( opacity: new Tween<double>(begin: 1.0, end: 0.0).animate(second), child: child, ), ); } ); break; case "/first": page = new PageRouteBuilder( pageBuilder: (BuildContext context,Animation<double> animation, Animation<double> secondaryAnimation){ return new Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ const Text("First Page",textDirection: TextDirection.ltr,), const Padding(padding: const EdgeInsets.all(10.0)), new GestureDetector(onTap: () => Navigator.of(context).pop(),child: new Container( padding: const EdgeInsets.all(10.0), color:Colors.blue, child: const Text("Back"),), ) ] ); }, transitionsBuilder: (_, Animation<double> animation, Animation<double> second, Widget child) { return new FadeTransition( opacity: animation, child: new FadeTransition( opacity: new Tween<double>(begin: 1.0, end: 0.0).animate(second), child: child, ), ); } ); break; } return page; } Route unKnownRoute(RouteSettings settings){ return new PageRouteBuilder( pageBuilder: (BuildContext context,Animation<double> animation, Animation<double> secondaryAnimation){ return new Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ const Text("First Page",textDirection: TextDirection.ltr,), const Padding(padding: const EdgeInsets.all(10.0)), new GestureDetector( onTap: () => Navigator.of(context).pop(), child: new Container( padding: const EdgeInsets.all(10.0), color:Colors.blue, child: const Text("Back"), ), ) ] ); } ); } @override Widget build(BuildContext context) { return new WidgetsApp( onGenerateRoute: generate, onUnknownRoute: unKnownRoute, textStyle: const TextStyle(), initialRoute: "/", color: Colors.red ); }}希望能有所帮助！
