fetch method

Implementation

@override
Future<List<T>> fetch({bool force = false}) async {
  // When performing a full refresh (force=true), we reset the pagination state
  if (force) {
    _nextPageParam = initialPageParam;
    _previousPageParam = null; // Reset previous
    hasNextPage.value = true;
    hasPreviousPage.value = false;
    isFetchingNextPage.value = false;
    isFetchingPreviousPage.value = false;

    // Cancel any ongoing "next/prev page" fetch
    _nextPageCancelToken?.cancel('Full refresh triggered');
    _nextPageCancelToken = null;
    _previousPageCancelToken?.cancel('Full refresh triggered');
    _previousPageCancelToken = null;
  }

  final result = await super.fetch(force: force);

  // After the initial page loads, calculate cursors
  if (!isDisposed && result.isNotEmpty) {
    _updateParams(result);
  }

  return result;
}
