Description
I have tried the sample given on this page regarding page restoration. When the application is running in debug mode (in app-debug.apk), the page restoration recovery is running. However, when the application is running in release (production) mode (in app-release.apk), the page restoration recovery freezes when switching from the application task via the multitask tray.
Steps to Reproduce
- Run
flutter create --sample=widgets.RestorableRouteFuture.1 mysamplefor creating project based on this sample. - Turn on developer mode and in these settings turn on "Don't keep activities".
- Run (through debug and release mode) this sample through phone/emulator.
- Create some in-memory state in the app on the phone, e.g. by navigating to a different screen.
- Background this sample app, then return to it.
Result

Expected results: Success restore its state.
