How to add more unique buttons in app?

[Davidm16]

Question

Hi, I would like to know if it is possible to add more buttons in app, that each one is independent and that they can return unique values. This example adds 10 buttons but always gives the last value

Code sample

import flet as ft

def main(page: ft.Page):
    r = ft.Row(wrap=True, scroll="always", expand=True)
    page.add(r)
    
    def pruebas(e):
        print(e)

    for i in range(10):
        r.controls.append(ft.ElevatedButton(i, on_click=lambda _:pruebas(i)),)
    page.update()

ft.app(target=main)

Error message

No response

You can do this:

    for i in range(10):
        r.controls.append(ft.ElevatedButton(i, data=i, on_click=lambda e: pruebas(e.control.data)))
