Code sample

import flet
from flet import IconButton, Page, Row, TextField, icons

def main(page: Page):
    page.title = "Flet counter example"
    page.vertical_alignment = "center"

    txt_number = TextField(value="0", text_align="right", width=100)

    def minus_click(e):
        txt_number.value = int(txt_number.value) - 1
        page.update()

    def plus_click(e):
        txt_number.value = int(txt_number.value) + 1
        page.update()

    page.add(
        Row(
            [
                IconButton(icons.REMOVE, on_click=minus_click),
                txt_number,
                IconButton(icons.ADD, on_click=plus_click),
            ],
            alignment="center",
        )
    )

flet.app(target=main)

Try running it with just python:

python3 <your-app.py>

I waited almost 1 minute. but the app doesn't open

code

import flet
from flet import IconButton, Page, Row, TextField, icons
import logging
logging.basicConfig(level=logging.DEBUG)
def main(page: Page):
    page.title = "Flet counter example"
    page.vertical_alignment = "center"

    txt_number = TextField(value="0", text_align="right", width=100)

    def minus_click(e):
        txt_number.value = int(txt_number.value) - 1
        page.update()

    def plus_click(e):
        txt_number.value = int(txt_number.value) + 1
        page.update()

    page.add(
        Row(
            [
                IconButton(icons.REMOVE, on_click=minus_click),
                txt_number,
                IconButton(icons.ADD, on_click=plus_click),

I also faced thesame issue with hot reload.... Freezing. I was then obliged to manually run my program every time.
I will try again later today and share the logs.
