Implementation
Future<void> acceptConnection(String endpointId) async {
var pending = _findDevice(pendingAcceptConnections, endpointId);
if (pending == null) {
return;
}
var device = addDeviceAsInitiatedConnection(pending);
await nearbyCross.acceptConnection(endpointId);
_executeCallback(callbackConnectionInitiated, device);
}
