Flutter图片轮播插件images_swiper的使用

Flutter图片轮播插件images_swiper的使用

功能特性

开始使用

在你的Flutter项目的pubspec.yaml文件中添加以下依赖：

dependencies:
  ...
  images_swiper:

然后在你的Dart文件中导入该库：

import 'package:images_swiper/images_swiper.dart';

使用方法

你可以使用ImagesSwiper或ImagesSwiper.builder来创建一个图片轮播组件。以下是两个示例：

示例1: 使用ImagesSwiper

ImagesSwiper(
  images: [
    "assets/1.jpg",
    "assets/2.jpg",
    "assets/3.jpg",
    "assets/4.jpg",
    "assets/5.jpg",
  ],
)

示例2: 使用ImagesSwiper.builder

ImagesSwiper.builder(
  imageCount: maxCount,
  alignment: Alignment.center,
  pageController: _pageController,
  imageBuilder: (context, index) => "assets/${index + 1}.jpg",
)

完整示例代码

以下是一个完整的示例代码，展示了如何在Flutter应用中使用images_swiper插件。

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

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

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

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter iMessage Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key});

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final maxCount = 5;
  late final _pageController = PageController(initialPage: 1);

  [@override](/user/override)
  void initState() {
    super.initState();
    _pageController.addListener(() {
      // 可以在这里处理一些事件
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('iMessage')),
      body: Column(
        children: [
          // 使用ImagesSwiper.builder创建轮播图
          ImagesSwiper.builder(
            imageCount: maxCount,
            alignment: Alignment.center,
            pageController: _pageController,
            imageBuilder: (context, index) => "assets/${index + 1}.jpg",
          ),
          const SizedBox(height: 50),
          Row(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              TextButton(
                onPressed: _onPrevious,
                child: const Text('⬅️', style: TextStyle(fontSize: 30)),
              ),
              const SizedBox(width: 50),
              TextButton(
                onPressed: _onNext,
                child: const Text('➡️', style: TextStyle(fontSize: 30)),
              ),
            ],
          )
        ],
      )
    );
  }

  _onPrevious() {
    _pageController.previousPage(
      duration: const Duration(milliseconds: 500),
      curve: Curves.easeOutQuad,
    );
  }

  _onNext() {
    _pageController.nextPage(
      duration: const Duration(milliseconds: 500),
      curve: Curves.easeOutQuad,
    );
  }
}
