addMember method

Future<void> addMember(LocationDataModel _newLocationDataModel)

we are assuming that the _newLocationDataModel has a new share id if it has a same id already in [allAtsignsLocationData_newLocationDataModel.receiver] then we won't add it again

Implementation

Future<void> addMember(LocationDataModel _newLocationDataModel) async {
  if (allAtsignsLocationData[_newLocationDataModel.receiver] != null) {
    /// don't add and send again if already present
    var _receiverLocationDataModel =
        allAtsignsLocationData[_newLocationDataModel.receiver]!;

    if (_newLocationDataModel.locationSharingFor.keys.isEmpty) {
      return;
    }

    var _id = _newLocationDataModel.locationSharingFor.keys.first;
    if (_receiverLocationDataModel.locationSharingFor[_id] != null) {
      return;
    }
  }

  // add
  _appendLocationDataModelData([_newLocationDataModel]);

  var locationDataModel = getLocationDataModel(_newLocationDataModel
      .receiver); // get updated (aggregated LocationDataModel)

  if (locationDataModel == null) {
    return;
  }

  var myLocation = await getMyLocation();
  if (myLocation != null) {
    await prepareLocationDataAndSend(
        locationDataModel.receiver, locationDataModel, myLocation);

    if (!masterSwitchState) {
      /// method from main app
      if (locationPromptDialog != null) {
        // _appendLocationDataModelData([locationDataModel]);
        locationPromptDialog!();

        /// return as when main switch is turned on, it will send location to all.
        return;
      }
    }
  } else {
    // ignore: unnecessary_null_comparison
    if (AtLocationNotificationListener().navKey != null) {
      CustomToast().show('Location permission not granted',
