debugDisableShadows top-level property
Whether to replace all shadows with solid color blocks.
This is useful when writing golden file tests (see matchesGoldenFile) since the rendering of shadows is not guaranteed to be pixel-for-pixel identical from version to version (or even from run to run).
In those tests, this is usually set to false at the beginning of a test and back to true before the end of the test case.
If it remains true when the test ends, an exception is thrown to avoid state leaking from one test case to another.
bool debugDisableShadows = false;
