Project description

Flet - quickly build interactive apps for web, desktop and mobile 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.

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

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

                ft.IconButton(ft.icons.REMOVE, on_click=minus_click),
