I'm reporting this because is what the error is suggesting:

I/flutter (23621): Either the assertion indicates an error in the framework itself, or we should provide substantially
I/flutter (23621): more information in this error message to help you determine and fix the underlying cause.
I/flutter (23621): In either case, please report this assertion by filing a bug on GitHub:
I/flutter (23621):   https://github.com/flutter/flutter/issues/new?template=2_bug.md

I tried this in Android and Web, and in Web it works without issues (with flutter run -d chrome). Only Android is affected for me. I'm using Flutter beta channel.

Steps to Reproduce

  1. Run flutter create bug11.
  3. Update the files as follows (based on the example in https://flutter.dev/docs/cookbook/forms/validation#interactive-example):

I marked important additions with // IMPORTANT, if any of these are removed, the error goes away.

code sample

  1. flutter run

  2. enter some text in the text input

  3. tap on "Submit"

  4. tap the back arrow or the back android button

Expected results: It goes back to the previous (home) screen and the text input is focused.

Actual results: An error message in the screen:

And an error message and stack trace on the flutter run console:
