It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group. |

A `CkImage` instance holds a reference to `ImageSource?`. When that `CkImage` gets cloned, the `ImageSource` instance becomes shared between the original `CkImage` and its new clone. Then when one of the `CkImage`s gets disposed of, it closes the shared `ImageSource` leaving other live `CkImage`s holding on to a closed `ImageSource`. The quick solution to this is to have a ref count on the `ImageSource` to count how many `CkImage`s are referencing it. The `ImageSource` will only be closed if its ref count reaches 0. Fixes flutter/flutter#160199 Fixes flutter/flutter#158093
