Flutter启动画面插件splash的使用

Flutter中的splash插件提供了多种自定义按钮按下效果，这些效果可以替代默认的InkSplash.splashFactory和InkRipple.splashFactory。本文将介绍如何在Flutter应用中使用该插件，并提供一个完整的示例代码。

插件概述

splash插件包含以下几种可选的启动画面效果：

• WaveSplash: 波浪效果
• PathSplash: 路径动画效果
• LineSplash: 线条动画效果
• NoSplash: 无启动画面效果

示例效果展示

Example	Usage
	WaveSplash.splashFactory, WaveSplash.customSplashFactory(strokeWidth: 30, blurStrength: 5)
	PathSplash.splashFactory(path), PathSplash.splashFactory(path, paint: paint, clip: false)
	LineSplash.splashFactory, LineSplash.customSplashFactory(paint: paint)
	NoSplash.splashFactory

如何使用

首先需要在pubspec.yaml文件中添加依赖：

dependencies:
  flutter:
    sdk: flutter
  splash: ^最新版本号

然后运行flutter pub get以安装插件。

接下来，在你的Flutter应用中使用不同的启动画面工厂方法。

在MaterialApp中使用

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

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        visualDensity: VisualDensity.adaptivePlatformDensity,
        splashFactory: WaveSplash.splashFactory, // 使用WaveSplash效果
      ),
      home: const MyHomePage(title: 'Demo'),
    );
  }
}

在按钮中使用

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

OutlinedButton(
  child: const Text('OutlineButton'),
  onPressed: () {},
  style: OutlinedButton.styleFrom(
    splashFactory: LineSplash.splashFactory, // 使用LineSplash效果
  ),
);

完整示例代码

以下是完整示例代码，展示了如何在应用中使用不同的启动画面效果：

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

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: const MyHomePage(title: 'Demo'),
    );
  }
}

class MyHomePage extends StatelessWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  Widget build(BuildContext context) {
    final simpleSamples = [
      SampleDesign(
        'InkSplash.splashFactory',
        'From the Flutter framework itself',
        Theme.of(context).copyWith(splashFactory: InkSplash.splashFactory),
      ),
      SampleDesign(
        'InkRipple.splashFactory',
        'From the Flutter framework itself',
        Theme.of(context).copyWith(
          splashFactory: InkRipple.splashFactory,
        ),
      ),
      SampleDesign(
        'LineSplash.splashFactory',
        'This splash factory creates an animated line',
        Theme.of(context).copyWith(
          splashFactory: LineSplash.splashFactory,
        ),
      ),
      // 其他SampleDesign实例...
    ].map((e) => listTileMapping(context, e)).toList(growable: false);

    return Scaffold(
      appBar: AppBar(
        title: Text(title),
      ),
      body: ListView(
        children: [
          Padding(
            padding: const EdgeInsets.all(16),
            child: Text(
              'Default theme with splash factory',
              style: Theme.of(context).textTheme.titleLarge,
            ),
          ),
          ...simpleSamples,
          // 更多内容...
        ],
      ),
    );
  }

  Widget listTileMapping(BuildContext context, SampleDesign e) {
    return ListTile(
      title: Text(e.title),
      subtitle: Text(e.subTitle),
      onTap: () {
        Navigator.push(
          context,
          MaterialPageRoute<void>(
            builder: (context) {
              return Theme(
                data: e.theme,
                child: Sample(
                  name: e.title,
                ),
              );
            },
          ),
        );
      },
    );
  }
}

// 其他类定义...
