Hi @372945980, you appear to be on an older version of flutter.

Kindly upgrade to the latest version of stable to see if you still experience this issue.

If you do, I will need a minimal sample in a repo (considering your use case isn't a standard one) that I can run without any modifications to verify this behavior.

Thank you

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
