  "message": "Add asserts to catch potential misuses of the rendering framework.\n\nNew asserts:\n- verify that after layout, the size fits the constraints\n- verify that after layout, the size isn\u0027t infinite\n- verify that you don\u0027t set the size in performLayout() if you have\n  sizedByParent set\n- verify that nobody reads your size during layout except you, or your\n  parent if they said parentUsesSize:true\n\nFixes some bugs found by those asserts:\n- RenderBlock, RenderStack, and RenderScaffold were not always setting\n  parentUsesSize correctly\n- RenderScaffold was setting its slot entries to null rather than\n  removing them when the slot went away, which led to null derefs in\n  certain circumstances\n\nAlso, rename a local variable in RenderStack.performLayout() because\nit was shadowing a variable on the object itself, which was really\nconfusing when I first tried to debug this function...\n\nR\u003dabarth@chromium.org\n\nReview URL: https://codereview.chromium.org/1213473003.\n",
