> [!NOTE] > To release engineer: this can definitely wait to be included in a hotfix beta release. I also want to CP this to 3.38 beta as part of a hotfix release: https://github.com/flutter/flutter/pull/177121 This pull request is created by [automatic cherry pick workflow](https://github.com/flutter/flutter/blob/main/docs/releases/Flutter-Cherrypick-Process.md#automatically-creates-a-cherry-pick-request) Please fill in the form below, and a flutter domain expert will evaluate this cherry pick request. ### Issue Link: What is the link to the issue this cherry-pick is addressing? https://github.com/flutter/flutter/issues/173770 ### Changelog Description: Explain this cherry pick in one line that is accessible to most Flutter developers. See [best practices](https://github.com/flutter/flutter/blob/main/docs/releases/Hotfix-Documentation-Best-Practices.md) for examples Mitigates a memory leak that occurs on Android, when `Activities` are not kept upon exit and an Activity is exited and re-entered. ### Impact Description: What is the impact (ex. visual jank on Samsung phones, app crash, cannot ship an iOS app)? Does it impact development (ex. flutter doctor crashes when Android Studio is installed), or the shipping production app (the app crashes on launch) Memory leak that will occur in production app but does not impact development. ### Workaround: Is there a workaround for this issue? Not that I know of. ### Risk: What is the risk level of this cherry-pick? ### Test Coverage: Are you confident that your fix is well-tested by automated tests? ### Validation Steps: What are the steps to validate that this fix works? Follow the steps in the [issue description](https://github.com/flutter/flutter/issues/173770#issue-3322196704), roughly: 1. Create a Flutter project. 2. Enter the developer options, set not to keep activities, (destroy each activity as soon as the user leaves it) 3. Entering the activity, clicking the home button, exiting the activity, and then entering the activity again will trigger the destruction and reconstruction of the activity. 4. Check memory leaks through profiler and find memory leaks.
