On building to windows/apk , app displays module not found error

[vishnu-rvb]

Description

I have a flask server that is running on the url 'http://192.168.0.103:5000' in which i intent to send http request. during Flet run command the app runs without any issue and building for windows or android apk is also a success, but when running the built file module not found error is seen. I have tried to place requests module folder directly into the root but now same error but different module is occurring.

import flet as ft
from ast import literal_eval as str2lst
import requests
def main(page: ft.Page):
    page.title='Server client test'
    row=ft.TextField(label='Enter Row',value='')
    value=ft.TextField(label='Enter value',value='')
    btn=ft.ElevatedButton(text='update')
    page.add(row,value,btn)
    def update(e):
        r=int(row.value)
        l=str2lst(value.value)
        url = 'http://192.168.0.103:5000'
        response= requests.put(url+'/update',
                               json={'row':r,'value':l})
        page.add(ft.Text(f'{response.text}'))
    btn.on_click=update

ft.app(main)

Error on executing the built windows executable:

i'm having the same issue while running flet build windows. I used poetry as dependency manager and it seems its not finding the dependencies installed. I've triied with erasing the version name of the dependencies in my requirements.txt and leaving just 3:

• flet
• python-docx
• pytz

But I find the same issue.

This problem still exist when I build Windows app that has additional third-party Python libraries in the source code. Using the latest version of flet to date (0.22.1).

I had a similar problem, and I solved it thanks to this comment --> Issue 2714

As it was a bit tedious, I decided to make a small tool to load dependencies to the windows builds (if you want to take a look). Flet Packages Loader

Good to hear that. 👍 Yesterday when I was finding out the root cause of this problem, I also noticed that the flet build did not use venv's packages/libraries to build the app. This should be fixed by telling flet build to look for local venv instead of global one.
