Why does this behavior happen in the event when I load a gridview?

[hanif40]

Hello!

I have a problem when I load elements into a grid through a loop, which is an icon and in its event I need it to print the path that would correspond to it.
The issue is that it always prints the one for the last element of the array.

import flet as ft
from flet import *

def main(page: ft.Page):
    items = [
             {
                "name": "Lampara",
                "description": "Configuracion de Lampara Inteligente",
                "order": 2,
                "route":"/lamp",
                "icon": "light",
                "tooltip": "Lampara Inteligente",
                "size": 250,
                "color": "green400",
                "active": True
            },
            {
                "name": "Clima",
                "description": "Informa sobre la Temperatura y Humedad de los sensores instalados.",
                "order": 1,
                "route":"/weather",
                "icon": "THERMOSTAT",
                "tooltip": "Temperatura & Humedad",
                "size": 250,
                "color": "blue400",
                "active": True
            },
            
        ]
    
    gv = ft.GridView(expand=1,runs_count=4,max_extent=510, child_aspect_ratio=1,spacing=1,run_spacing=1)
    for m in items:
        gv.controls.append(ft.Container(content=ft.IconButton(key=m['name'],icon=m['icon'],icon_color=m['color'],icon_size=m['size'],tooltip=m['tooltip'],expand=True,on_click=lambda _:print(m['route'])),
            border_radius=10,
            bgcolor="blue",
            padding=10,
            margin=10,
            shadow=ft.BoxShadow.color,
            alignment=ft.alignment.center))

    
    page.add(gv)
    page.update()
        

ft.app(target=main)

The second element is always printed although each icon corresponds to its image.

I guess you‘re facing a late binding problem.
