[widget_test] pumpWidget on Chip with EdgeInsets.symmetric causes _RenderChip violation of intrinsic protocol contract exception

[kurakurakuda]

Hi, all.

I am creating widget test refer to https://flutter.dev/docs/testing .
When I test the page including chip widget, I encoutered this error.

When running the app, there is no error.
Could you help this ?
Error is below.

logs

══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
The following assertion was thrown during performLayout():
The intrinsic dimension methods of the _RenderChip class returned values that violate the intrinsic
protocol contract.
The following failure was detected:
 * getMinIntrinsicWidth(Infinity) returned a larger value (90.0) than getMaxIntrinsicWidth(Infinity)
(86.0)
If you are not writing your own RenderBox subclass, then this is not
your fault. Contact support: https://github.com/flutter/flutter/issues/new?template=BUG.md

The relevant error-causing widget was:
  Chip

══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
The following assertion was thrown during performLayout():
The intrinsic dimension methods of the _RenderChip class returned values that violate the intrinsic
protocol contract.
The following failure was detected:
 * getMinIntrinsicWidth(Infinity) returned a larger value (94.0) than getMaxIntrinsicWidth(Infinity)
(86.0)
If you are not writing your own RenderBox subclass, then this is not
your fault. Contact support: https://github.com/flutter/flutter/issues/new?template=BUG.md

The relevant error-causing widget was:
  Chip

Any update on this?

[kurakurakuda]

@Onwa1kenobi
Still have error.

[kowongh]

I'm getting this error as well.

[markusaksli-nc]

Reproducible on the latest master 1.22.0-10.0.pre.269. The failure seems to be caused by padding: EdgeInsets.symmetric.

Exception and stack

══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
The following assertion was thrown during performLayout():
The intrinsic dimension methods of the _RenderChip class returned values that violate the intrinsic
protocol contract.
The following failures was detected:
 * getMinIntrinsicWidth(Infinity) returned a larger value (52.0) than getMaxIntrinsicWidth(Infinity)
(44.0)
 * getMinIntrinsicWidth(544.0) returned a larger value (52.0) than getMaxIntrinsicWidth(544.0)
(44.0)
If you are not writing your own RenderBox subclass, then this is not
your fault. Contact support: https://github.com/flutter/flutter/issues/new?template=BUG.md
