reicons

Reicon icon font for Flutter — 2700+ 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	2675	`ReiconIcons`	`Icon(ReiconIcons.home)`
Filled	2680	`ReiconFilledIcons`	`Icon(ReiconFilledIcons.home)`

Install

Add to your pubspec.yaml:

dependencies:
  reicons: ^1.0.3

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,
)

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`
`3d-box`	`ReiconIcons.i3dBox`
`align-center-h`	`ReiconIcons.alignCenterH`
`user-circle`	`ReiconIcons.userCircle`

Names starting with a digit are prefixed with i (e.g. 3d-box → i3dBox).

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..

Known limitations

5 Outline icons that use SVG <rect> or <polyline> elements (not <path>) are not included in the font. Their Filled variants are fully supported:

Excluded Outline icon	Filled alternative
`window-chart-line`	`ReiconFilledIcons.windowChartLine`
`align-3-horizontal`	`ReiconFilledIcons.align3Horizontal`
`align-3-left`	`ReiconFilledIcons.align3Left`
`align-3-right`	`ReiconFilledIcons.align3Right`
`images-2`	`ReiconFilledIcons.images2`

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 cu2qu
python tool/fetch_icons.py
python tool/build_font.py

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