+/// CH34 Flutter 插件。
+///
+/// 用于与 WCH CH34X 系列 USB 转串口芯片进行通信。
+///
+/// 支持的芯片：CH340/CH341/CH342/CH343/CH344/CH347/CH9101/CH9102/CH9103/CH9104/CH9143
+///
+/// 使用方法：
+/// ```dart
+/// import 'package:ch34/ch34.dart';
+///
+/// // 初始化插件（必须在首次调用 Ch34Manager 前调用）
+/// Ch34.ensureInitialized();
+///
+/// // 枚举设备
+/// final devices = await Ch34Manager.enumDevice();
+///
+/// // 打开设备
+/// await Ch34Manager.openDevice(devices.first.deviceName);
+///
+/// // 设置参数
+/// await Ch34Manager.setSerialParameter(
+///   devices.first.deviceName,
+///   0,
+///   const SerialParameter(baud: 9600),
+/// );
+///
+/// // 发送数据
+/// await Ch34Manager.writeData(
+///   devices.first.deviceName,
+///   0,
+///   Uint8List.fromList([0x01, 0x02]),
+/// );
+///
+/// // 注册数据回调
+/// Ch34Manager.registerDataCallback(
+///   devices.first.deviceName,
+///   0,
+///   (data) { print('Received: $data'); },
+/// );
