chatItems method

Future<GetMessages$Query> chatItems(
  1. ChatId id, {
  2. int? first,
  3. ChatItemsCursor? after,
  4. int? last,
  5. ChatItemsCursor? before,
  6. ChatItemsFilter? filter,
})

Fetches ChatItems of a Chat identified by its id ordered by their posting time.

It is allowed to specify both first and last at the same time provided that after and before are equal. In such cases the returned page will include the ChatItem pointed by the cursor and the requested number of ChatItems preceding and following it.

If it is desired to receive the ChatItem under the cursor without querying in both directions one can specify first or last as 0.

Authentication

Mandatory.

  ChatId id, {
  int? first,
  ChatItemsCursor? after,
  int? last,
  ChatItemsCursor? before,
  ChatItemsFilter? filter,
}) async {
  Log.debug(
    'chatItems($id, first: $first, after: $after, last: $last, before: $before, filter: $filter)',
    '$runtimeType',
  );

  final variables = GetMessagesArguments(
    id: id,
    first: first,
    after: after,
    last: last,
    before: before,
    filter: filter,
  );
  final QueryResult result = await client.query(
    QueryOptions(
      operationName: 'GetMessages',
      document: GetMessagesQuery(variables: variables).document,
      variables: variables.toJson(),
    ),
  );
  return GetMessages$Query.fromJson(result.data!);
