Create a modern UI using Flet in Python. 😍

Hi 🙂🖐

In this post, I will share with you how to Create a modern UI using Flet in Python.

What is Flet 🤔

Flet is a framework that allows building interactive multi-user web, desktop and mobile applications in your favorite language without prior experience in frontend development.

You build a UI for your program with Flet controls which are based on Flutter by Google. Flet does not just "wrap" Flutter widgets, but adds its own "opinion" by combining smaller widgets, hiding complexities, implementing UI best-practices, applying reasonable defaults - all to ensure your apps look cool and professional without extra efforts.

Install flet

pip install flet

Flet app example

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(target=main)
