I want to create a simple stopwatch in Python using the Flet, how can I get my value out of the while loop?

I want it to be possible to navigate through the bottom panel between pages, and for each of these pages to be able to view information by pressing a button at the top of the screen
I was able to do each function separately, but I can’t combine it(

I want to expand a flet(Python) container whic is in a Column wich is in a Row, that fills all the space horizontally.
Maybe get the page width. But then I want to publish into Android.
Really hope you can help me.

I had a simple goal; the application in Web mode opens a file selection by clicking on the button. I select a config file for myself, for example, and the contents of the file appear in the TextField.

I’m trying to add a drawer to my learning project, however I can’t understand why it always shows as unknown control, I’m following the documentation and some YouTube channels to learn, but at this stage I couldn’t understand , even using the append method it is still unknown

The message in the terminal stays there forever and apparently crashes

I need to change sizes of switch in flet, but I can’t find controls for it anywhere.
