Parameter expand doesn't change

[antonnurapkin]

I have this structure of my main page:

[Container(expand=1), all_widgets(expand=part),Container(expand=1)],
where part= 5

Empty containers need for adaptive padding. When I make other window sizes, I want to change the relation of containers and widgets by changing the variable.

But it doesn't happened after assignment of variable

If I understand the question correctly: You need to update all_widgets.expand to the new value, and call update() as well. Variables are not dynamically connected whenever they are used to set some other value, and thus just changing the value of part will not magically update the expand value. This is not a feature or failure of flet, but just how Python and most other languages work, and I would not expect this to change any time soon.
