示例代码

以下是nian_dev_kit插件的基本使用示例。此示例展示了如何在Flutter应用中集成并使用该插件。

import 'dart:io';

import 'package:nian_dev_kit/dev_kit.dart';
import 'package:nian_dev_kit/page/channel_monitor/src/core/devkit_binary_messenger.dart';
import 'package:nian_dev_kit/page/custom_plug/custom_pluggable.dart';
import 'package:nian_dev_kit/utils/app_log_utils.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await logInit();
  
  // 设置透明状态栏
  if (Platform.isAndroid) {
    SystemUiOverlayStyle systemUiOverlayStyle =
        const SystemUiOverlayStyle(statusBarColor: Colors.transparent);
    SystemChrome.setSystemUIOverlayStyle(systemUiOverlayStyle);
  }
  runApp(const MyApp());
}

Future logInit() async {
  await KitAppLog.init();
}

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

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> with WidgetsBindingObserver {
  // 这个小部件是你的应用的根组件

  @override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addObserver(this); // 注册监听器
  }

  @override
  void dispose() {
    super.dispose();
    WidgetsBinding.instance.removeObserver(this);
  }

  @override
  Widget build(BuildContext context) {
    return DevKit(
      enable: true,
      pluginsList: [
        CustomPluggable(),
      ],
      child: MaterialApp(
        title: 'Flutter Demo',
        theme: ThemeData(
          colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
          useMaterial3: false,
        ),
        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> {
  int _counter = 0;

  String methodChannel = "nian_an/methodChannel";
  
  Future<void> testMethodCall() async {
    // 1. 创建Flutter端的MethodChannel
    MethodChannel method = MethodChannel(
      methodChannel,
      const StandardMethodCodec(),
      DevKitBinaryMessenger.binaryMessenger,
    );
    
    // 2. 通过invokeMethod调用Native方法，拿到返回值
    String debugString = await method.invokeMethod(
        "give_$_counter",
        Platform.isAndroid
            ? "($_counter)give me debug info"
            : "ios_($_counter) give me debug info");
    debugPrint('test debugString=$debugString');
  }

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
    testMethodCall();
    KitAppLog.i(_counter);
  }

  @override
  void initState() {
    super.initState();
  }

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

说明

1. 初始化:

   void main() async {
     WidgetsFlutterBinding.ensureInitialized();
     await logInit();
   
     if (Platform.isAndroid) {
       SystemUiOverlayStyle systemUiOverlayStyle =
           const SystemUiOverlayStyle(statusBarColor: Colors.transparent);
       SystemChrome.setSystemUIOverlayStyle(systemUiOverlayStyle);
     }
     runApp(const MyApp());
   }
   

2. 日志初始化:

   Future logInit() async {
     await KitAppLog.init();
   }
   

3. 使用DevKit:

   class MyApp extends StatefulWidget {
     const MyApp({super.key});
   
     @override
     State<MyApp> createState() => _MyAppState();
   }
   
   class _MyAppState extends State<MyApp> with WidgetsBindingObserver {
     @override
     void initState() {
       super.initState();
       WidgetsBinding.instance.addObserver(this);
     }
   
     @override
     void dispose() {
       super.dispose();
       WidgetsBinding.instance.removeObserver(this);
     }
   
     @override
     Widget build(BuildContext context) {
       return DevKit(
         enable: true,
         pluginsList: [
           CustomPluggable(),
         ],
         child: MaterialApp(
           title: 'Flutter Demo',
           theme: ThemeData(
             colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
             useMaterial3: false,
           ),
           home: const MyHomePage(title: 'Flutter Demo Home Page'),
         ),
       );
     }
   }
   

4. 测试MethodChannel:

   class _MyHomePageState extends State<MyHomePage> {
     int _counter = 0;
     String methodChannel = "nian_an/methodChannel";
   
     Future<void> testMethodCall() async {
       MethodChannel method = MethodChannel(
         methodChannel,
         const StandardMethodCodec(),
         DevKitBinaryMessenger.binaryMessenger,
       );
   
       String debugString = await method.invokeMethod(
           "give_$_counter",
           Platform.isAndroid
               ? "($_counter)give me debug info"
               : "ios_($_counter) give me debug info");
       debugPrint('test debugString=$debugString');
     }
   
     void _incrementCounter() {
       setState(() {
         _counter++;
       });
       testMethodCall();
       KitAppLog.i(_counter);
     }
