update method
override
Updates the golden file identified by golden
with rendered pixels of
width
xheight
.
This will be invoked in lieu of compare when autoUpdateGoldenFiles
is true
(which gets set automatically by the test framework when the
user runs flutter test --update-goldens --platform=chrome
).
The method by which golden
is located and by which its bytes are written
is left up to the implementation class.

@override
Future<void> update(double width, double height, Uri golden) {
throw UnsupportedError('DefaultWebGoldenComparator is only supported on the web.');
