Have you tested the newly added API? There is no this api's unit test in shared_preferences's integration_test. (Tested on each platform implementation.)

In this case, it is better to write the results in the comment after testing.

getAllWithParameters and clearWithParameters are used by other methods in original shared_preferences package. It seems they omit test about two api's because if they don't work properly, other methods won't work properly.

However, even before clearWithParameters's failed was fixed, integration_test was still all pass.

Yes. I think I was wrong. It seems the test of original package missed this point. For more accurate test, we need to add more test code.
