Blank/empty UI on second run of app in Android emulator. #149328
Description
Steps to reproduce
Hello, this is an issue I'm seeing with a brand new flutter project on a local Android emulator.
flutter emulators --launch Pixel_7_API_VanillaIceCream
flutter create helpme
cd helpme
flutter run -d emulator-5554
At this point the application launches correctly, everything seems fine. I then close the application and rerun from inside the emulator and the application starts but everything is blank (white, nothing rendered). I believe the application is running fine, but there seems to be an issue with painting/rendering the UI.
Every time you run the application using flutter run it will correctly start.
A significant clue: If I clear the app cache, I'm able to run the application again. This is very reproducible. Effectively, to run the application, clearing the cache is necessary.
Forgive me if I'm leaving out anything critical in this bug report, it's my first time filing one with this project.
Thanks so much.
Expected results
There to be no difference when running a brand new app the second time and that to run a second time clearing the cache is not necessary.
Actual results
Running the app a second time w/o clearing the app cache results in a blank window with no UI rendered.
Code sample
I am able to reproduce this by creating a new project using:
flutter create helpme

Logs
Logs
I'm happy to provide these, but due to the nature of the issue the logs seem fine to me, and in order to reproduce the device connection must be lost. Happy to provide adb logs, though if those will help.
