This pull request was opened against a branch other than master. Since Flutter pull requests should not normally be opened against branches other than master, I have changed the base to master. If this was intended, you may modify the base back to flutter-1.17-candidate.3. See the Release Process for information about how other branches get updated.

Reviewers: Use caution before merging pull requests to branches other than master. The circumstances where this is valid are very rare.
