Placeholder comparator that is set as the value of goldenFileComparator when the initialization that happens in the test bootstrap either has not yet happened or has been bypassed.
The test bootstrap file that gets generated by the Flutter tool when the
flutter test is expected to set goldenFileComparator to
a comparator that resolves golden file references relative to the test
directory. From there, the caller may choose to override the comparator by
setting it to another value during test initialization. The only case
where we expect it to remain uninitialized is when the user runs a test
flutter run. In this case, the compare method will just print a
message that it would have otherwise run a real comparison, and it will
return trivial success.
This class can't be constructed. It represents the default value of goldenFileComparator.
