Implementation

@override

  List<ChatItem> repliesTo = const [],
}) async {

    if (text == null && attachments.isEmpty && repliesTo.isEmpty) {
      if (draft != null) {
        await _draftLocal.delete(id);
      }
    } else {

      final bool attachmentsEqual = const IterableEquality().equals(
        (draft?.attachments ?? []).map((e) => [e.id, e.runtimeType]),
        attachments.map((e) => [e.id, e.runtimeType]),
      );

          PreciseDateTime.now(),
