reicons

Reicon icon font for Flutter — 2,600+ precision-crafted, open-source SVG icons in Outline and Filled weights, bundled as a single icon font (.ttf) with generated Dart constants.

Weight	Icons	Dart class	Example
Outline	2676	ReiconIcons	Icon(ReiconIcons.home)
Filled	2676	ReiconFilledIcons	Icon(ReiconFilledIcons.home)

Install

Add to your pubspec.yaml:

dependencies:
  reicons: ^2.0.0

Then run:

flutter pub get

Usage

import 'package:reicons/reicons.dart';

Outline icons (default)

Icon(ReiconIcons.home)
Icon(ReiconIcons.arrowDown2)
Icon(ReiconIcons.settings)

Filled icons

Icon(ReiconFilledIcons.home)
Icon(ReiconFilledIcons.arrowDown2)
Icon(ReiconFilledIcons.settings)

With custom size and color

Icon(
  ReiconIcons.star,
  size: 32,
  color: Colors.amber,
)

In a widget tree

Row(
  children: [
    Icon(ReiconIcons.heart),
    SizedBox(width: 8),
    Text("Like"),
    IconButton(
      icon: Icon(ReiconFilledIcons.heart),
      onPressed: () {},
    ),
  ],
)

Icon naming conventions

All icon names use camelCase:

Original (kebab)	Dart constant
arrow-down2	ReiconIcons.arrowDown2
align-h-center	ReiconIcons.alignHCenter
user-circle	ReiconIcons.userCircle

A name starting with a digit would be prefixed with i (3d-box → i3dBox).

A few names appear in two reicon.dev categories with different artwork. The second one gets its category appended, e.g. arrow-down2 in newicons → ReiconIcons.arrowDown2Newicons.

Upgrading from 1.x? See MIGRATION.md for every renamed icon.

Finding icons

Browse all icons at reicon.dev/icons. The Dart constant name follows the same kebab→camelCase conversion shown above.

You can also search icons locally by browsing the generated constants — any IDE with autocomplete will show all options after typing ReiconIcons..

Building from source (maintainers only)

Regular users don't need this. The font and Dart constants are pre-built.
Just add reicons to your pubspec.yaml and run flutter pub get.

If you want to regenerate the font from the latest icon data:

pip install fonttools picosvg skia-pathops
python tool/fetch_icons.py --force
python tool/build_font.py

This produces lib/fonts/Reicon.ttf and lib/reicons.dart.

Before publishing, check that every glyph still renders like its source SVG:

pip install skia-python numpy pillow
python tool/check_render.py

It rasterizes each icon from the SVG and from the font, and exits non-zero listing any icon whose shapes differ (missing parts, circles drawn as rounded squares, filled-in holes). Pass --sheet failures.png to get a side-by-side image of the failing icons. loader is allowlisted because it uses opacity, which a single-color font cannot represent.
