Flutter自定义路由PageRouteBuilder

自定义路由翻转，渐变，左右滑动

方法如下：

首先继承 PageRouteBuilder ，重写方法
将MaterialPageRoute改为showSearch

importpackage:flutter/material.dart;class animation_route extendsPageRouteBuilder{finalWidget widget; animation_route(this.widget):super( transitionDuration:constDuration(milliseconds:500),//设置动画时长500毫秒 pageBuilder:(BuildContext context,Animation<double> animation1,Animation<double> animation2){return widget;}, transitionsBuilder:(BuildContext context,Animation<double>animation1,Animation<double> animation2,Widget child){//渐变过渡// return FadeTransition(//渐变过渡 0.0-1.0// opacity: Tween(begin: 0.0, end: 1.0).animate(CurvedAnimation(// parent: animation1, //动画样式// curve: Curves.fastOutSlowIn, //动画曲线// )),// child: child,// );//翻转缩放// return RotationTransition(// turns: Tween(begin: 0.0, end: 1.0).// animate(// CurvedAnimation(// parent: animation1,// curve: Curves.fastOutSlowIn,// )// ),// child: ScaleTransition(// scale: Tween(begin: 0.0, end: 1.0).// animate(CurvedAnimation(parent: animation1, curve: Curves.fastOutSlowIn)),// child: child,// ),// );//左右滑动returnSlideTransition( position:Tween<Offset>(begin:Offset(-1.0,0.0),end:Offset(0.0,0.0)).animate(CurvedAnimation(parent: animation1, curve:Curves.fastOutSlowIn)),child: child,);});}

　　使用方法

Navigator.push(context, MaterialPageRoute(builder: (context){ return test(); })); 改为Navigator.push(context, animation_route(test()));
