decline method

Implementation

Future<void> decline(ChatId chatId) async {
  Log.debug('decline($chatId)', '$runtimeType');

  final Rx<OngoingCall>? call = _callRepository[chatId];
  if (call != null) {
    // Closing the popup window will kill the pending requests, so it's
    // required to await the decline.
    if (WebUtils.isPopup) {
      await _callRepository.decline(chatId);

      // First, try to mark the `Chat` this call is taking place it as read.
      await _maybeMarkAsRead(chatId);

      // Setting `OngoingCallState` to `ended` will make `PopupCallController`
      // to close itself, thus this should be done only after every mutation
      // occurs.
      call.value.state.value = OngoingCallState.ended;
      call.value.dispose();
    } else {
      call.value.state.value = OngoingCallState.ended;

      // Try to mark the `Chat` this call is taking place it as read.
