connectionState property

Implementation

Stream<BluetoothConnectionState> get connectionState {
  // initial value - Note: we only care about the current connection state of
  // *our* app, which is why we can use our cached value, or assume disconnected
  BluetoothConnectionState initialValue =
      BluetoothConnectionState.disconnected;
  if (FlutterBluePlus._connectionStates[remoteId] != null) {
    initialValue = _bmToConnectionState(
        FlutterBluePlus._connectionStates[remoteId]!.connectionState);
  }
  return FlutterBluePlusPlatform.instance.onConnectionStateChanged
      .where((p) => p.remoteId == remoteId)
      .map((p) => _bmToConnectionState(p.connectionState))
      .newStreamWithInitialValue(initialValue);
