flet-material-symbols

A Flet extension that provides Material Symbols icons for use in Flet apps.

Material Symbols is Google's latest icon library, offering outlined, rounded, and sharp variants for over 3,000 icons. The icons support variable font axes: fill, weight, grade, and optical size.

Usage

import flet as ft
from flet_material_symbols import Symbols

def main(page: ft.Page):
    page.add(
        ft.Icon(Symbols.HOME),
        ft.Icon(Symbols.HOME_ROUNDED),
        ft.Icon(Symbols.HOME_SHARP),
    )

ft.run(main)

Icon variants

Each icon is available in three styles:

• Outlined (default): Symbols.ICON_NAME
• Rounded: Symbols.ICON_NAME_ROUNDED
• Sharp: Symbols.ICON_NAME_SHARP

Variable font axes

Icons can be customized with variable font axes using the standard ft.Icon properties:

ft.Icon(
    Symbols.SETTINGS,
    fill=1,        # 0.0 = outlined, 1.0 = fully filled (continuous 0–1)
    weight=700,    # 100–700
    grade=0.25,    # -50–200
    optical_size=48,  # 20–48
)

Updating icon data

To regenerate the icon data after a material_symbols_icons package update, run from the flet-material-symbols directory:

uv run scripts/generate_icons.py
