Hi，Is automatic update of controls possible in the future

[kunandikun]

I really like flet.
I have a lot of custom combinations of controls that need to be rebuilt after “before_update”.
This makes my code not easy to maintain!
I would really like to have controls that update automatically when the user triggers some events on the control.
I sincerely hope that flet will be updated in this direction, my request may be a bit too much!
I'm very sorry, I'm not a native English speaker, I'm using a translation program to do the translation
I'm just a python learner, I don't know flutter, thanks to the author I would like to express my love for flet here
