super_native_extensions_syncme 是一个用于在 Flutter 应用中实现原生扩展同步功能的插件。它允许你在 Flutter 和原生平台（如 Android 和 iOS）之间进行数据同步和通信。以下是如何使用该插件的基本步骤：

1. 添加依赖

首先，你需要在 pubspec.yaml 文件中添加 super_native_extensions_syncme 插件的依赖：

dependencies:
  flutter:
    sdk: flutter
  super_native_extensions_syncme: ^1.0.0  # 使用最新版本

然后运行 flutter pub get 来获取依赖。

2. 初始化插件

在你的 Flutter 应用中，你需要在 main.dart 文件中初始化插件：

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

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await SuperNativeExtensionsSyncme.initialize();
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

3. 使用插件进行数据同步

你可以使用 SuperNativeExtensionsSyncme 提供的方法来在 Flutter 和原生平台之间进行数据同步。以下是一个简单的例子，展示了如何在 Flutter 和原生平台之间同步数据：

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

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String _syncData = 'No data yet';

  Future<void> _syncDataWithNative() async {
    try {
      final String data = await SuperNativeExtensionsSyncme.syncData('Hello from Flutter');
      setState(() {
        _syncData = data;
      });
    } catch (e) {
      setState(() {
        _syncData = 'Error: $e';
      });
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Super Native Extensions SyncMe'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text(
              'Sync Data:',
            ),
            Text(
              _syncData,
              style: Theme.of(context).textTheme.headline4,
            ),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: _syncDataWithNative,
              child: Text('Sync Data with Native'),
            ),
          ],
        ),
      ),
    );
  }
}

4. 原生平台实现

你需要在 Android 和 iOS 平台上实现 SuperNativeExtensionsSyncme 的原生代码。以下是一个简单的 Android 实现示例：

Android (Java/Kotlin)

在 MainActivity.kt 中实现 SuperNativeExtensionsSyncmePlugin 的回调：

import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugin.common.MethodChannel
import com.example.super_native_extensions_syncme.SuperNativeExtensionsSyncmePlugin

class MainActivity: FlutterActivity() {
    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
        super.configureFlutterEngine(flutterEngine)
        SuperNativeExtensionsSyncmePlugin.setMethodCallHandler { call, result ->
            if (call.method == "syncData") {
                val data = call.arguments as String
                result.success("Hello from Android: $data")
            } else {
                result.notImplemented()
            }
        }
    }
}

iOS (Swift)

在 AppDelegate.swift 中实现 SuperNativeExtensionsSyncmePlugin 的回调：

import UIKit
import Flutter
import super_native_extensions_syncme

[@UIApplicationMain](/user/UIApplicationMain)
[@objc](/user/objc) class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    
    SuperNativeExtensionsSyncmePlugin.setMethodCallHandler { (call, result) in
        if call.method == "syncData" {
            let data = call.arguments as! String
            result("Hello from iOS: \(data)")
        } else {
            result(FlutterMethodNotImplemented)
        }
    }
    
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}
