Describe the bug

Hi,

I have an issue when using my build flet app on Windows. When opening it and I greeted to an error with the error info being

import win32com.client
ModuleNotFoundError: No module named 'win32com'

My app works fine running it in the terminal but for some reason the built flet app hates win32com. And yes, it is in my requirements.txt but that doesn't seem to matter

Code sample

Code

import win32com.client

To reproduce

Add "import win32com.client" to code that is built using Flet

Expected behavior

It is expected to launch like how it does within the terminal but throws an error on the built application

I feel like this issue would be resolved if there was an option in Flet build for --hidden-import like there is for Flet Pack https://flet.dev/docs/reference/cli/pack. Can this option be added for flet build?

[zeldridge]

I have tried using flet pack over flet build and while the --hidden-import does infact allow me to built my flet app for windows, I much preferred the output of flet build and the way flet pack doesn't really satisfy my needs. Is the hidden import argument able to be added to flet build @ndonkoHenri @FeodorFitsner ?

[zeldridge]

Can I get any update on support for pywin32 or adding a --hidden-import option to flet build command? I can not use flet currently for my project
