hi ,

in my opinion ,the problem is not related to Flutter, not directly.
here, it's FLET 0.23 and more precisely it's the change in flet Runtime from version 0.22.1 to version 0.23.
so , making corrections to Flutter will not solve the problem,

it's my opinion

The thing is Flet 0.22.1 was built back then against Flutter 3.19.6 while this new 0.23.0 release is built against Flutter 3.22.2.
That's why I think it's the cause of this issue.
Also, error messages in flutter/flutter#144873 look like those you received.

But does the app work with those assertions or it crashes?

I am not an expert in FLET but I like it a lot and I use it more and more, I dont know if the transition to Flutter 3.22.2 was an absolute necessity to evolve FLET (and I think not) but in in the present case there is no solution to this Bug because even if I correct this bug in my machine and in my package (FLET 0.23) the bug will reappear during the packaging of the application or during the execution of the application in an another machine.
to be more precise, the bug is related to Flutter 3.22 which is the basis of flet 0.23 so two solutions are possible:

  • use an earlier version of flutter 3.19 or 3.20 i version for an update of FLET 0.23.1 (the most intelligent solution)

Or

  • wait for the official correction in a future version of Flutter (it may take a long time) which will be very unpleasant for FLET.

@FeodorFitsner: at my level of 'skill' I think it's not going to work, and even if I delve deeper into correcting the code of Flet 0.23 (or on my_application.cc), at best it will only work on my machine

It's just my opinion and my analysis

Does the app start with the assertions shown or crash?

I can reproduce the bug on my install of Ubuntu 22.04 (ARM) and looks like I'm going to have a fix for that...
