Flutter页面动画切换插件animated_page_reveal的使用

动画页面揭示插件简介

AnimatedPageReveal 插件允许你在 Flutter 应用中添加一个动画页面揭示效果，展示一组带有你所需内容的页面。默认情况下，内容的位置设置为 Center，通过使用 ViewPageModel，你可以添加任意数量的页面，并自定义每个页面的内容。

特性

• 动画页面：通过在屏幕上拖动（从左到右或从右到左），一个页面淡出，另一个页面以酷炫的动画淡入。
• 底部图标：底部图标指示当前激活页面的位置以及剩余可见和不可见的页面，供用户交互。

示例代码

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

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

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

  // 这个 widget 是是你的应用根节点。
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key}) : super(key: key);

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return SizedBox(
      width: MediaQuery.of(context).size.width,
      height: MediaQuery.of(context).size.height,
      child: AnimatedPageReveal(children: [
