Assertion "lookup_hash_table" fails on ToDo App example

[qertoip]

** (flet:31142): CRITICAL **: 10:04:19.347: void update_pressing_state(FlKeyEmbedderResponder *, uint64_t, uint64_t): assertion 'lookup_hash_table(self->pressing_records, physical_key) == 0' failed

This happens on the console while playing with the ToDo App example w/o modifications. The GUI seems functional.

Could you provide more info please? What OS are you running the example on? What command did you user to run it? Screenshot with an error would help too. Thanks!

Linux with the latest stable Python. The error message I cited just repeats itself on the terminal with no further details. Should be easy to recreate by just running unmodified ToDo App example and doing anything in the GUI. Again, the GUI works despite assertion failures.

I'm testing it on Ubuntu 20.04 (though Python is 3.8, not the latest) and it looks "good":

What distro/version of Linux are you running it on? Could you catch the steps to reproduce?

Please just press and hold any key in the top text field, entering something like aaaaaaaaaaaaaaaaaaaaa.

I am on the fully updated Arch Linux but that is probably not the key factor.

Indeed, I can reproduce the issue in such a way:

Looks like it's going to be fixed in the next Flutter 3.1 release: flutter/flutter#104870 (comment)

Will close this issue when it's released and the fix is verified.
