Flutter自定义图标模态框插件custom_icon_modal_widget的使用

特性

这是一个简单的自定义模态框。

开始使用

在pubspec.yaml文件中添加以下依赖：

dependencies:
  custom_icon_modal_widget: 0.0.1

然后运行 flutter pub get 命令以获取该包。

使用方法

可以在示例代码中查看正确的用法。

import 'package:custom_icon_modal_widget/helper/modal_helper.dart';
import 'package:flutter/material.dart';

// 创建一个自定义模态框实例
CustomIconModal customIconModal = CustomIconModal();

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

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

  @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
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  // 初始化自定义模态框实例
  CustomIconModal customIconModal = CustomIconModal();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text(
              '你已经点击了按钮很多次:',
            ),
            Text(
              'Hello World',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        // 点击按钮时显示模态框
        onPressed: () {
          customIconModal.showDialogModalIcon(
            context: context,
            iconData: Icons.info,
            title: '模态框标题',
            subtitle: '模态框副标题',
            buttonText: '关闭',
          );
        },
        tooltip: '增加',
        child: const Icon(Icons.add),
      ),
    );
  }
}

代码解释

1. 导入必要的库：

   import 'package:custom_icon_modal_widget/helper/modal_helper.dart';
   import 'package:flutter/material.dart';
   

2. 创建自定义模态框实例：

   CustomIconModal customIconModal = CustomIconModal();
   

3. 初始化应用并设置主页：

   void main() {
     runApp(const MyApp());
   }
   
   class MyApp extends StatelessWidget {
     const MyApp({super.key});
   
     @override
     Widget build(BuildContext context) {
       return MaterialApp(
         title: 'Flutter Demo',
         theme: ThemeData(
           primarySwatch: Colors.blue,
         ),
         home: const MyHomePage(title: 'Flutter Demo Home Page'),
       );
     }
   }
   

4. 创建主页状态类：

   class MyHomePage extends StatefulWidget {
     const MyHomePage({super.key, required this.title});
   
     final String title;
   
     @override
     State<MyHomePage> createState() => _MyHomePageState();
   }
   

5. 在状态类中实现按钮点击事件以显示模态框：

   class _MyHomePageState extends State<MyHomePage> {
     CustomIconModal customIconModal = CustomIconModal();
   
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         appBar: AppBar(
           title: Text(widget.title),
         ),
         body: Center(
           child: Column(
             mainAxisAlignment: MainAxisAlignment.center,
             children: <Widget>[
               const Text(
                 '你已经点击了按钮很多次:',
               ),
               Text(
                 'Hello World',
                 style: Theme.of(context).textTheme.headlineMedium,
               ),
             ],
           ),
         ),
         floatingActionButton: FloatingActionButton(
           onPressed: () {
             customIconModal.showDialogModalIcon(
               context: context,
               iconData: Icons.info,
               title: '模态框标题',
               subtitle: '模态框副标题',
               buttonText: '关闭',
             );
           },
           tooltip: '增加',
           child: const Icon(Icons.add),
         ),
       );
     }
   }
