Hi @jimexist. Thanks for your PR.

I'm waiting for a kubernetes or tensorflow member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

There are so many of them, I plan to fix them in next patch. Note that most of them are just missing prop-types, so my motivation for adding this is to try to enforce people to add prop-types upon submission.

@jimexist Change LGTM. Looks like the files are out of date though and need to be synced.
