Flutter自定义路由过渡动画插件custom_route_transition_ph的使用

Flutter 自定义路由过渡动画插件 custom_route_transition_ph 的使用

路由过渡

这个包可以帮助实现页面之间的过渡效果。

使用示例

import 'package:flutter/material.dart';
import 'package:custom_route_transition_ph/custom_route_transition_ph.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Material App',
      initialRoute: 'page1',
      routes: {
        'page1': (_) => Page1(),
        'page2': (_) => Page2(),
      },
    );
  }
}

class Page1 extends StatelessWidget {
  const Page1({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Page1'),
        backgroundColor: Colors.transparent,
      ),
      backgroundColor: Colors.red,
      body: Center(
        child: MaterialButton(
          color: Colors.white,
          child: Text('Page 2'),
          onPressed: () {
            RouteTransitions(
              context: context,
              child: Page2(),
              animation: AnimationType.fadeIn,
              duration: Duration(seconds: 2),
              replacement: true
            );
          }
        ),
      ),
    );
  }
}

class Page2 extends StatelessWidget {
  const Page2({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Page2'),
        backgroundColor: Colors.transparent,
      ),
      backgroundColor: Colors.lightBlue,
    );
  }
}

代码解释

1. 导入库

   import 'package:flutter/material.dart';
   import 'package:custom_route_transition_ph/custom_route_transition_ph.dart';
   

2. 创建应用

   void main() => runApp(MyApp());
   

3. 创建 MyApp 类

   class MyApp extends StatelessWidget {
     @override
     Widget build(BuildContext context) {
       return MaterialApp(
         debugShowCheckedModeBanner: false,
         title: 'Material App',
         initialRoute: 'page1',
         routes: {
           'page1': (_) => Page1(),
           'page2': (_) => Page2(),
         },
       );
     }
   }
   

4. 创建 Page1 类

   class Page1 extends StatelessWidget {
     const Page1({Key? key}) : super(key: key);
   
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         appBar: AppBar(
           title: Text('Page1'),
           backgroundColor: Colors.transparent,
         ),
         backgroundColor: Colors.red,
         body: Center(
           child: MaterialButton(
             color: Colors.white,
             child: Text('Page 2'),
             onPressed: () {
               RouteTransitions(
                 context: context,
                 child: Page2(),
                 animation: AnimationType.fadeIn,
                 duration: Duration(seconds: 2),
                 replacement: true
               );
             }
           ),
         ),
       );
     }
   }
   

5. 创建 Page2 类

   class Page2 extends StatelessWidget {
     const Page2({Key? key}) : super(key: key);
   
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         appBar: AppBar(
           title: Text('Page2'),
           backgroundColor: Colors.transparent,
         ),
         backgroundColor: Colors.lightBlue,
       );
     }
   }
