pubspec.yaml 添加依赖

将 OpenClaw 与 Flutter 应用集成，通常指的是在 Flutter 应用中集成 OpenClaw 机器人控制功能，以下是几种常见的集成方法：

通信方式集成

网络 API 集成

// 使用 http 包与 OpenClaw 的 REST API 通信
import 'package:http/http.dart' as http;
class OpenClawController {
  final String baseUrl;
  Future<void> controlClaw(String command) async {
    final response = await http.post(
      Uri.parse('$baseUrl/api/claw'),
      body: {'command': command},
    );
    if (response.statusCode == 200) {
      print('Command executed successfully');
    }
  }
  Future<Map<String, dynamic>> getStatus() async {
    final response = await http.get(Uri.parse('$baseUrl/api/status'));
    return jsonDecode(response.body);
  }
}

WebSocket 实时通信

import 'package:web_socket_channel/web_socket_channel.dart';
class OpenClawWebSocket {
  WebSocketChannel? _channel;
  void connect(String url) {
    _channel = WebSocketChannel.connect(Uri.parse(url));
    _channel!.stream.listen(
      (message) => _handleMessage(message),
      onError: (error) => print('Error: $error'),
    );
  }
  void sendCommand(String command) {
    _channel?.sink.add(command);
  }
  void disconnect() {
    _channel?.sink.close();
  }
}

硬件直接通信

蓝牙集成（BLE）

  flutter_blue_plus: ^1.10.5

import 'package:flutter_blue_plus/flutter_blue_plus.dart';
class OpenClawBluetooth {
  BluetoothDevice? _device;
  BluetoothCharacteristic? _controlCharacteristic;
  Future<void> connectToDevice() async {
    // 扫描设备
    await FlutterBluePlus.startScan(timeout: Duration(seconds: 4));
    // 连接目标设备
    _device = await findOpenClawDevice();
    await _device!.connect();
    // 发现服务
    List<BluetoothService> services = await _device!.discoverServices();
    // 找到控制特征值
    for (var service in services) {
      for (var characteristic in service.characteristics) {
        if (characteristic.uuid.toString() == 'YOUR_UUID_HERE') {
          _controlCharacteristic = characteristic;
        }
      }
    }
  }
  Future<void> sendBluetoothCommand(List<int> command) async {
    if (_controlCharacteristic != null) {
      await _controlCharacteristic!.write(command);
    }
  }
}

串口通信

dependencies:
  flutter_libserialport: ^0.2.0

import 'package:flutter_libserialport/flutter_libserialport.dart';
class OpenClawSerial {
  SerialPort? _port;
  Future<void> connect(String portName) async {
    _port = SerialPort(portName);
    final config = SerialPortConfig()
      ..baudRate = 9600
      ..bits = 8
      ..stopBits = 1
      ..parity = SerialPortParity.none;
    _port!.config = config;
    if (!_port!.openReadWrite()) {
      throw Exception('Failed to open port');
    }
  }
  void sendCommand(String command) {
    _port!.write(Uint8List.fromList(command.codeUnits));
  }
}

完整的集成示例

控制界面组件

import 'package:flutter/material.dart';
class OpenClawControlScreen extends StatefulWidget {
  @override
  _OpenClawControlScreenState createState() => _OpenClawControlScreenState();
}
class _OpenClawControlScreenState extends State<OpenClawControlScreen> {
  final OpenClawController _controller = OpenClawController();
  bool _isConnected = false;
  @override
  void initState() {
    super.initState();
    _connectToClaw();
  }
  Future<void> _connectToClaw() async {
    try {
      await _controller.connect('192.168.1.100');
      setState(() => _isConnected = true);
    } catch (e) {
      print('Connection failed: $e');
    }
  }
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('OpenClaw Control')),
      body: Column(
        children: [
          // 连接状态指示
          ConnectionStatusIndicator(isConnected: _isConnected),
          // 控制按钮
          Expanded(
            child: GridView.count(
              crossAxisCount: 3,
              children: [
                ControlButton(
                  icon: Icons.arrow_upward,
                  onPressed: () => _controller.sendCommand('UP'),
                ),
                ControlButton(
                  icon: Icons.arrow_downward,
                  onPressed: () => _controller.sendCommand('DOWN'),
                ),
                ControlButton(
                  icon: Icons.catching_pokemon,
                  onPressed: () => _controller.sendCommand('GRAB'),
                ),
                ControlButton(
                  icon: Icons.release,
                  onPressed: () => _controller.sendCommand('RELEASE'),
                ),
              ],
            ),
          ),
          // 状态监控
          StatusMonitor(controller: _controller),
        ],
      ),
    );
  }
}

平台特定配置

Android 配置

<!-- android/app/src/main/AndroidManifest.xml -->
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>

iOS 配置

<!-- ios/Runner/Info.plist -->
<dict>
  <key>NSBluetoothAlwaysUsageDescription</key>
  <string>需要蓝牙权限来控制OpenClaw</string>
  <key>NSBluetoothPeripheralUsageDescription</key>
  <string>需要蓝牙权限来控制OpenClaw</string>
</dict>

最佳实践建议

1. 异步处理：所有硬件通信都应该是异步的
2. 错误处理：实现完善的错误处理和重试机制
3. 状态管理：使用 Provider、Bloc 或 Riverpod 管理连接状态
4. 安全考虑：
   • 实现身份验证
   • 使用加密通信
   • 添加操作确认对话框

调试建议

class OpenClawDebugHelper {
  static void log(String message) {
    debugPrint('[OpenClaw] $message');
  }
  static void simulateCommands(OpenClawController controller) {
    // 模拟命令用于测试
    controller.sendCommand('TEST');
  }
}

根据您的 OpenClaw 具体型号和通信协议，可能需要调整上述代码，建议查阅 OpenClaw 的官方文档获取详细的通信协议说明。
