路由router 添加动画效果

import 'package:flutter/material.dart';

class CustomeRouter extends PageRouteBuilder {
  final Widget widget;
  CustomeRouter(this.widget)
      : super(
            transitionDuration: Duration(seconds: 1),
            pageBuilder: (BuildContext context, Animation animation1,
                Animation animation2) {
              return widget;
            },
            transitionsBuilder: (BuildContext context,
                Animation<double> animation1,
                Animation<double> animation2,
                Widget child) {
              return SlideTransition(
                  position: Tween<Offset>(
                          begin: Offset(-1.0, 0.0), end: Offset(0.0, 0.0))
                      .animate(CurvedAnimation(
                          parent: animation1,
                          curve: Curves.fastLinearToSlowEaseIn)),
                  child: child);
              // return FadeTransition(
              //   opacity: Tween(begin: 0.0, end: 1.0).animate(CurvedAnimation(
              //       parent: animation1, curve: Curves.fastOutSlowIn)),
              //   child: child,
              // );
            });
}

使用

import 'custom_router.dart';

Navigator.of(context).push(CustomeRouter(secentpage()))
