使用Flutter构建特定的导航动画

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomeScreen(),
    );
  }
}

class HomeScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Home Screen'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            Navigator.push(
              context,
              PageRouteBuilder(
                pageBuilder: (context, animation, secondaryAnimation) => SecondScreen(),
                transitionsBuilder: (context, animation, secondaryAnimation, child) {
                  var begin = Offset(1.0, 0.0);
                  var end = Offset.zero;
                  var curve = Curves.ease;

                  var tween = Tween(begin: begin, end: end).chain(CurveTween(curve: curve));

                  return SlideTransition(
                    position: animation.drive(tween),
                    child: child,
                  );
                },
              ),
            );
          },
          child: Text('Go to Second Screen'),
        ),
      ),
    );
  }
}

class SecondScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Second Screen'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            Navigator.pop(context);
          },
          child: Text('Go Back'),
        ),
      ),
    );
  }
}
