debugResetSize method
override
If a subclass has a "size" (the state controlled by parentUsesSize,
whatever it is in the subclass, e.g. the actual size property of
RenderBox), and the subclass verifies that in debug mode this "size"
property isn't used when debugCanParentUseSize isn't set, then that
subclass should override debugResetSize to reapply the current values of
debugCanParentUseSize to that state.
Implementation
@override
void debugResetSize() { }
