removeContact method

Future<void> removeContact(
  1. ChatContactId contactId,
  2. UserId userId
)

Removes the provided ChatContactId from the User.contacts with the specified UserId.

Intended to be invoked from ContactRepository, as RxUser has no events of its User.contacts list changes.

Implementation

Future<void> removeContact(ChatContactId contactId, UserId userId) async {
  Log.debug('removeContact($contactId, $userId)', '$runtimeType');

  final DtoUser? dto = await _userLocal.read(userId);
  if (dto != null) {
    final NestedChatContact? existing = dto.value.contacts.firstWhereOrNull(
      (e) => e.id == contactId,
    );

    if (existing != null) {
      dto.value.contacts.remove(existing);
      await _userLocal.upsert(dto);
    }
  }
}
