FLET: A python GUI based on Flutter

I am always on the lookout for new (easier) ways to create GUIs for python. Recently I ran across the FLET. Also available on github.

Their description is

The fastest way to build Flutter apps in Python
Flet enables developers to easily build realtime web, mobile and desktop apps in Python. No frontend experience required.

As an experiment I decided to create a simple login form.

import flet as ft

def main(page: ft.Page):
    page.title = "Login"
    page.window_height = 200
    page.window_width = 500
    page.window_always_on_top = True

    def cancel_click(e):
        page.window_destroy()

    def login_click(e):
        if txt_user.value == "admin" and txt_pwd.value == "admin":
            dlg.content = ft.Text("Login Successful")
        else:
            dlg.content = ft.Text("Login failed")
        dlg.modal = False
        dlg.open = True
        dlg.update()
        page.update()

    dlg = ft.AlertDialog(title=ft.Text("Login"), content=ft.Text("---"))
    txt_user = ft.TextField(value = "", label="User ID")
    txt_pwd = ft.TextField(value = "", password=True, can_reveal_password=True, 
label="Password")
    btn_cancel = ft.FilledButton(text="Cancel", on_click=cancel_click)
    btn_login = ft.FilledButton(text="Login", on_click=login_click)
    action_row = ft.Row(controls=[btn_cancel, btn_login])
    page.add(txt_user, txt_pwd, action_row, dlg)
    page.window_center()

ft.app(target=main)

This results in the following window
