鸿蒙Next如何集成flutter_blue_plus
在鸿蒙Next系统上开发应用时,如何正确集成flutter_blue_plus插件实现蓝牙功能?目前按照Flutter官方文档配置后,插件在鸿蒙环境下无法正常初始化,日志显示找不到原生平台适配代码。是否需要针对鸿蒙系统进行特殊适配?具体需要修改哪些配置文件或添加哪些依赖?有没有成功案例可以参考?

鸿蒙Next集成flutter_blue_plus?简单!先确保你的鸿蒙项目支持Flutter,然后在pubspec.yaml里添加flutter_blue_plus依赖。接着,在代码里import,初始化蓝牙适配器,开始扫描设备。记住:鸿蒙的权限配置别漏了蓝牙权限!搞定后,你的应用就能愉快地和蓝牙设备玩耍啦~

在鸿蒙Next中集成flutter_blue_plus需要结合OpenHarmony的蓝牙API和Flutter插件机制。以下是实现步骤:
-
环境准备
- 安装OpenHarmony SDK和Flutter SDK
- 创建Flutter项目并添加依赖:
dependencies: flutter_blue_plus: ^1.0.0 -
配置鸿蒙权限 在
module.json5中添加蓝牙权限:{ "module": { "requestPermissions": [ { "name": "ohos.permission.USE_BLUETOOTH" }, { "name": "ohos.permission.DISCOVER_BLUETOOTH" }, { "name": "ohos.permission.MANAGE_BLUETOOTH" } ] } } -
平台适配实现 创建原生通道处理鸿蒙蓝牙操作:
// flutter_blue_plus鸿蒙适配 class HarmonyBleAdapter { static const MethodChannel _channel = MethodChannel('flutter_blue_plus/harmony'); static Future<void> initialize() async { await _channel.invokeMethod('initialize'); } static Future<List<BluetoothDevice>> scanDevices() async { final result = await _channel.invokeMethod('scanDevices'); return _parseDevices(result); } } -
鸿蒙原生实现 在
entry/src/main/java创建蓝牙服务:public class BlePlugin implements FlutterPlugin { private BluetoothController bluetoothController; @Override public void onAttachedToEngine(FlutterPluginBinding binding) { MethodChannel channel = new MethodChannel( binding.getBinaryMessenger(), "flutter_blue_plus/harmony" ); bluetoothController = new BluetoothController(); channel.setMethodCallHandler(this::handleMethodCall); } private void handleMethodCall(MethodCall call, Result result) { switch (call.method) { case "initialize": bluetoothController.enableBluetooth(); result.success(null); break; case "scanDevices": List<BluetoothDevice> devices = bluetoothController.scanDevices(); result.success(devices); break; } } } -
使用示例
void main() { HarmonyBleAdapter.initialize(); runApp(MyApp()); } class BleScreen extends StatefulWidget { @override _BleScreenState createState() => _BleScreenState(); } class _BleScreenState extends State<BleScreen> { List<BluetoothDevice> devices = []; void scanDevices() async { var result = await HarmonyBleAdapter.scanDevices(); setState(() => devices = result); } }
注意事项:
- 需要处理鸿蒙与Flutter的数据类型转换
- 注意蓝牙生命周期管理
- 测试时需要真机设备支持
- 目前需要自行实现完整的API映射
建议参考OpenHarmony蓝牙开发文档和flutter_blue_plus的API文档进行完整实现。
