Flet for Python - easily build interactive multi-platform apps in Python
Flet is a rich User Interface (UI) framework to quickly build interactive web, desktop and mobile apps in Python without prior knowledge of web technologies like HTTP, HTML, CSS or JavaSscript. You build UI with controls based on Flutter widgets to ensure your programs look cool and professional.
pip install flet

import flet as ft
def main(page: ft.Page):
page.title = "Flet counter example"
page.vertical_alignment = ft.MainAxisAlignment.CENTER
txt_number = ft.TextField(value="0", text_align=ft.TextAlign.RIGHT, width=100)
def minus_click(e):
txt_number.value = str(int(txt_number.value) - 1)
page.update()
def plus_click(e):
txt_number.value = str(int(txt_number.value) + 1)
page.update()
page.add(
ft.Row(
[
ft.IconButton(ft.icons.REMOVE, on_click=minus_click),
txt_number,
ft.IconButton(ft.icons.ADD, on_click=plus_click),
],
alignment=ft.MainAxisAlignment.CENTER,
)
)
ft.app(main)
The following command will start the app in a native OS window:
