RenderBox did not set its size during layout.

Because this RenderBox has sizedByParent set to true, it must set its size in performResize().
It appears that this did not happen; layout completed, but the size property is still null.
The RenderBox in question is: GameRenderBox#7a1b6 NEEDS-LAYOUT NEEDS-PAINT
parentData: (can use size)
constraints: BoxConstraints(w=827.8, h=411.4)
size: MISSING
When the exception was thrown, this was the stack:
#0 RenderBox.debugAssertDoesMeetConstraints. (package:flutter/src/rendering/box.dart:2175:9)
