ModalRoute

import 'package:flutter/material.dart';class TutorialOverlay extends ModalRoute<void> {  @override  Duration get transitionDuration => Duration(milliseconds: 500);  @override  bool get opaque => false;  @override  bool get barrierDismissible => false;  @override  Color get barrierColor => Colors.black.withOpacity(0.5);  @override  String get barrierLabel => null;  @override  bool get maintainState => true;  @override  Widget buildPage(      BuildContext context,      Animation<double> animation,      Animation<double> secondaryAnimation,      ) {    // This makes sure that text and other content follows the material style    return Material(      type: MaterialType.transparency,      // make sure that the overlay content is not cut off      child: SafeArea(        child: _buildOverlayContent(context),      ),    );  }  Widget _buildOverlayContent(BuildContext context) {    return Center(      child: Column(        mainAxisSize: MainAxisSize.min,        children: <Widget>[          Text( 'This is a nice overlay', style: TextStyle(color: Colors.white, fontSize: 30.0),          ),          RaisedButton( onPressed: () => Navigator.pop(context), child: Text('Dismiss'),          )        ],      ),    );  }  @override  Widget buildTransitions(      BuildContext context, Animation<double> animation, Animation<double> secondaryAnimation, Widget child) {    // You can add your own animations for the overlay content    return FadeTransition(      opacity: animation,      child: ScaleTransition(        scale: animation,        child: child,      ),    );  }}// Example application:void main() => runApp(MyApp());class MyApp extends StatelessWidget {  @override  Widget build(BuildContext context) {    return MaterialApp(      title: 'Flutter Playground',      home: TestPage(),    );  }}class TestPage extends StatelessWidget {  void _showOverlay(BuildContext context) {    Navigator.of(context).push(TutorialOverlay());  }  @override  Widget build(BuildContext context) {    return Scaffold(      appBar: AppBar(title: Text('Test')),      body: Padding(        padding: EdgeInsets.all(16.0),        child: Center(          child: RaisedButton( onPressed: () => _showOverlay(context), child: Text('Show Overlay'),          ),        ),      ),    );  }}
