Description

opened on Aug 18, 2026

Steps to reproduce

  1. Run the following minimal reproduction code on any platform with a window or constrained width <= 300.

Expected results

Unlike RenderFlex (Row / Column), which gracefully assigns 0.0 width/height to flexible children when no free space remains, RenderSliverCrossAxisGroup crashes unconditionally.

SliverCrossAxisGroup should allow flexible children to be laid out with a cross-axis extent of 0.0 without asserting, matching the behavior of Flex / Expanded.

Actual results

Raise a SliverCrossAxisGroup ran out of extent before child could be laid out. exception.

Code sample

════════ Exception caught by rendering library ═════════════════════════════════
The following assertion was thrown during performLayout():
SliverCrossAxisGroup ran out of extent before child could be laid out.
SliverCrossAxisGroup lays out any slivers with a constrained cross axis before laying out those which expand. In this case, cross axis extent was used up before the next sliver could be laid out.
Make sure that the total amount of extent allocated by constrained child slivers does not exceed the cross axis extent that is available for the SliverCrossAxisGroup.

The relevant error-causing widget was:
    SliverCrossAxisGroup SliverCrossAxisGroup:file:///Users/***/dev/open-source/flutter_tester/lib/cases/sliver_constraints.dart:16:13

    I agree this should work the same way as Flex/Expanded.

    @mbcorona, @JayeshJain25 just to clarify: this PR #191287 is currently kept in draft simply because I am out of office at the moment. I plan to pick this back up next Tuesday to finalize the implementation and tests, if that works for everyone.

    @JayeshJain25, would you be interested in teaming up so we can wrap this up together?
