Extend LastChildLayoutType.fullCrossAxisExtent to leading item

[dna-f]

Hi,
is there a way to extend fullCrossAxisExtent to the first item?
Imagine a loader on the top of the grid or a button to reload content in case of errors ...

      lastChildLayoutTypeBuilder: (index) {
        if ((index == 0 && reloadRequired) ||
            ((index == 0 && isLoadingAll) ||
                (index == dataLength - 1 && isLoadingMore)) ||
            (index == dataLength - 1 && !isLoadingAll)) {
          return LastChildLayoutType.fullCrossAxisExtent;
        }

        return LastChildLayoutType.none;
      },

Thanks,
Andrea

CustomScrollview will better

[dna-f]

Hi,
I'm already using a CustomScrollview and between its slivers, there is a component (I made), a sort of "black box", that is listening on the stream of data.
The waterflow_flow widget is embedded inside this component.
The component receives the stream of data and should decide to show the loader on top of the list, during a refresh, a loader at the bottom during an "infinite" more items loading, or a retry button on the top in case of errors.
The component exposes a single sliver to the CustomScrollview .. so i should find a way to use the waterflow_flow to add items on top and bottom

Any idea?
Thanks,
Andrea
