Chip

Chips are compact elements that represent an attribute, text, entity, or action.

Chips help people enter information, make selections, filter content, or trigger actions. Use chips to show options for a specific context.

Examples​

Live example

Assist chips​

Assist chips are chips with leading icon and on_click event specified. They represent smart or automated actions that appear dynamically and contextually in a UI.

An alternative to assist chips are buttons, which should appear persistently and consistently.

import flet as ft


def main(page: ft.Page):
    def save_to_favorites_clicked(e):
        e.control.label.value = "Saved to favorites"
        e.control.leading = ft.Icon(ft.Icons.FAVORITE_OUTLINED)
        e.control.disabled = True
        page.update()

    def open_google_maps(e):
        page.launch_url("https://maps.google.com")
        page.update()

    save_to_favourites = ft.Chip(
        label=ft.Text("Save to favourites"),
        leading=ft.Icon(ft.Icons.FAVORITE_BORDER_OUTLINED),
        bgcolor=ft.Colors.GREEN_200,
        disabled_color=ft.Colors.GREEN_100,
        autofocus=True,
        on_click=save_to_favorites_clicked,
    )

    open_in_maps = ft.Chip(
        label=ft.Text("9 min walk"),
        leading=ft.Icon(ft.Icons.MAP_SHARP),
        bgcolor=ft.Colors.GREEN_200,
        on_click=open_google_maps,
    )

    page.add(ft.Row([save_to_favourites, open_in_maps]))

Filter chips​

Filter chips are chips with on_select event specified. They use tags or descriptive words provided in the label to filter content. They can be a good alternative to switches or checkboxes.

import flet as ft

def main(page: ft.Page):
    def amenity_selected(e):
        page.update()

    title = ft.Row([ft.Icon(ft.Icons.HOTEL_CLASS), ft.Text("Amenities")])
    amenities = ["Washer / Dryer", "Ramp access", "Dogs OK", "Cats OK", "Smoke-free"]
    amenity_chips = []

    for amenity in amenities:
        amenity_chips.append(
            ft.Chip(
                label=ft.Text(amenity),
                bgcolor=ft.Colors.GREEN_200,
                disabled_color=ft.Colors.GREEN_100,
                autofocus=True,
                on_select=amenity_selected,
            )
        )

    page.add(title, ft.Row(amenity_chips))

ft.app(main)
