startCommunicationChannel abstract method

FutureOr<bool> startCommunicationChannel(
  1. NearbyCommunicationChannelData data
)

If the device is already connected, it does not mean that you can send and receive data.

There is a separate function for this in NearbyService - communication channel. You need to call startCommunicationChannel before using send. A communication channel can only be created if you are connected to some device.

You can monitor changes in communication channel state using the communicationChannelState getter.

Implementation

FutureOr<bool> startCommunicationChannel(
  NearbyCommunicationChannelData data,
);
