Flutter UI组件插件mh_ui的使用

Flutter UI组件插件mh_ui的使用

在本教程中，我们将介绍如何使用mh_ui插件来构建一个简单的Flutter应用。mh_ui插件提供了丰富的UI组件，使开发过程更加简单。

示例代码

首先，确保你已经在项目的pubspec.yaml文件中添加了mh_ui依赖：

dependencies:
  mh_ui: ^最新版本号

然后运行flutter pub get以获取该依赖项。

接下来，我们来看一个完整的示例代码，展示了如何使用mh_ui插件创建一个简单的Flutter应用。

示例代码

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

void main() {
  runApp(const MyApp());
  //
  Service.setLoadingWidget(
    Image.asset(
      'assets/loading-c.gif',
      height: 30,
      width: 30,
    ),
  );
}

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

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

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

  final String title;

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

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            const Text(
              '你已经点击按钮次数:',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ),
    );
  }
}

在这个示例中，我们主要使用了mh_ui插件中的Service.setLoadingWidget方法来自定义加载动画。

完整示例代码

以下是一个完整的示例代码，展示如何使用mh_ui插件创建一个包含自定义网络图像的页面。

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

void main() {
  runApp(const MyApp());
  //
  Service.setLoadingWidget(
    Image.asset(
      'assets/loading-c.gif',
      height: 30,
      width: 30,
    ),
  );
}

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

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

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

  final String title;

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

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            const Text(
              '你已经点击按钮次数:',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
            // 使用mh_ui中的CustomNetworkImage
            CustomNetworkImage(
              networkImagePath: 'https://www.example.com/image.jpg',
              width: 100,
              height: 100,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ),
    );
  }
}
