Exception when list is on scroll more and new items(chats) are added to stream.

[ericel]

I get the following exception when list is in load more and chat items are added to scream.

══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following RangeError was thrown building StreamBuilder<int>(dirty, state:
_StreamBuilderBaseState<int, AsyncSnapshot<int>>#1312e):
RangeError (index): Invalid value: Not in inclusive range 0..19: 59
The relevant error-causing widget was:

package:app/…/state_widgets/chat_home_widget.dart:182
When the exception was thrown, this was the stack:
#0      List.[] (dart:core-patch/growable_array.dart:166:60)
#1      _StickyGroupedListViewState._showFixedGroupHeader
package:sticky_grouped_list/sticky_grouped_list.dart:324
#2      _StickyGroupedListViewState.build.<anonymous closure>
package:sticky_grouped_list/sticky_grouped_list.dart:24

I checked this behavior with native listview.builder but didn't get any such error.

But sticky_group_list causes this exception.

I'm facing the same issue, any update on this?
