How Do I Remove An Item From a ListView Control?

[AaronCatolico]

I've looked all over the Flet.dev docs, but couldn't find any solution.

I have a ListView control with nested controls such as; Text, PopupMenuButton & PopupMenuItem.
When I click on a name in the list, the PopupMenuButton appears with the option to 'Remove' a name from the list.
Here's what I have so far:

from flet import *

def main(page: flet.Page):
    page.window_width = 400
    page.window_height = 300
    page.window_center()
    page.bgcolor = '#333333'
    page.theme_mode = 'dark'
    page.update()


    def remove_name(n):
        # WHAT NEED'S TO GO HERE TO REMOVE A SELECTED NAME?
        print(n)


    lv1 = ListView(expand=True)

    list_of_names = ['Adam Smith', 'Billy Jones', 'Chris Wright', 'David Bates', 'Edward Hass', 'Frank Trigg', 'George Hintenbooger', 'Howard Bass']

    for name in list_of_names:
        lv1.controls.append(
            PopupMenuButton(content=Text(f'{name}', color='white', weight='bold', size=16),
                items=[
                    PopupMenuItem(content=Row([Text('REMOVE', size=12)]), data=f'{name}', on_click=lambda e: remove_name(e.control.data))
                ]
            )
        )

    page.add(lv1)


flet.app(target=main)

Is there some way to remove a child from the ListView that matches the data value (the name in this case) that was selected?

Try this. I added some little comments to help you understand. If you still don't, then let me know.

from flet import *

def main(page: flet.Page):
    page.window_width = 400
    page.window_height = 300
    page.window_center()
    page.bgcolor = '#333333'
    page.theme_mode = 'dark'
    page.update()

    def remove_name(n):
        print(f"{n[0]=} | {n[1]=}")
        lv1.controls.remove(n[1])
        page.update()

    lv1 = ListView(expand=True)

    list_of_names = ['Adam Smith', 'Billy Jones', 'Chris Wright', 'David Bates', 'Edward Hass', 'Frank Trigg',
                     'George Hintenbooger', 'Howard Bass']

    for name in list_of_names:
        # store the button in a variable
        my_item = PopupMenuButton(content=Text(f'{name}', color='white', weight='bold', size=16))

        my_item.items = [
            PopupMenuItem(
                content=Row([Text('REMOVE', size=12)]),
                data=(name, my_item),  ## <-------------------- store the reference to the button in a tuple. You could store it in a dictionary or whatever else you want
                on_click=lambda e: remove_name(e.control.data))
        ]
        lv1.controls.append(
            my_item
        )

    page.add(lv1)


flet.app(target=main)
