无法使用 Flutter_bluetooth_serial 包连接到设备

如何解决无法使用 Flutter_bluetooth_serial 包连接到设备

但是我收到那个错误

D/FlutterBluePlugin(3903)：连接到 74:DF:BF:9B:46:2E (id: 2) I/BluetoothAdapter(3903):canceldiscovery I/BluetoothAdapter(3903): canceldiscovery = false D/BluetoothUtils（3903）： isSocketAllowedBySecurityPolicy start : device null I/BluetoothSocket( 3903): connect() 用于设备 74DFBF 调用的 pid: 3903 W/BluetoothAdapter(3903): getBluetoothService() 调用时没有 BluetoothManagerCallback I/Flutter（3903）： PlatformException（连接错误，读取失败，套接字可能关闭或 超时，读取 ret：-1，java.io.IOException：读取失败，套接字可能 关闭或超时，读取 ret: -1 I/Flutter ( 3903): at android.bluetooth.BluetoothSocket.readAll(BluetoothSocket.java:970) I/颤振（3903）：在 android.bluetooth.BluetoothSocket.readInt(BluetoothSocket.java:984) I/颤振（3903）：在 android.bluetooth.BluetoothSocket.connect(BluetoothSocket.java:536) I/颤振（3903）：在 io.github.edufolly.Flutterbluetoothserial.BluetoothConnection.connect(BluetoothConnection.java:57) I/颤振（3903）：在 io.github.edufolly.Flutterbluetoothserial.BluetoothConnection.connect(BluetoothConnection.java:64) I/颤振（3903）：在 io.github.edufolly.Flutterbluetoothserial.FlutterBluetoothSerialPlugin.lambda$onMethodCall$0$FlutterBluetoothSerialPlugin(FlutterBluetoothSerialPlugin.java:880) I/颤振（3903）：在 io.github.edufolly.Flutterbluetoothserial.-$$Lambda$FlutterBluetoothSerialPlugin$IghJwXXwUz_TFyaj49DgLpHhUY4.run（未知 来源：10) I/Flutter (3903)：在 android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:305) I/颤振（3903）：在 java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoo

这是我的连接代码

Future<bool> connect(String address) async {
    BluetoothConnection _bluetoothConnection;
    try {
      _bluetoothConnection = await BluetoothConnection.toAddress(address);
      return _bluetoothConnection.isConnected ? true : false;
    } catch (e) {
      print(e);
    }
  }
