elk_stroke_icons

Pub Version License

All Lucide icons for Flutter, drawn with CustomPainter from generated Dart data. No icon fonts, no SVG assets, and no dependencies beyond Flutter.

Unofficial. Not affiliated with or endorsed by the Lucide project. The icon data comes from Lucide under the ISC License; see LICENSE-LUCIDE.

Need a picker UI? See elk_icon_picker, which builds on this package.

Why CustomPainter?

  1. No font bloat: no .ttf/.otf to ship.
  2. Dynamic styling: stroke width and rounding change at runtime without pixelation.
  3. Cheap at runtime: primitives are stored as typed Dart data; complex paths are parsed once and cached.

Usage

dependencies:
  elk_stroke_icons: ^0.1.1

import 'package:elk_stroke_icons/elk_stroke_icons.dart';

LucideIcon(
  LucideIcons.house,
  size: 32,
  color: Colors.blue,
  strokeWidth: 2.5,
)
Property Description Default

Searching

final results = IconSearchService.filter('arrow', categoryId: 'navigation');

kLucideIcons is the full list and kLucideCategories holds Lucide's categories.

Saving and restoring an icon by name

Store the icon's name (e.g. 'circle-check') and look it up again with IconSearchService.findByName. Lucide occasionally renames icons upstream; old names (e.g. 'smile', now 'face-slightly-smiling') still resolve via kLucideIconAliases, so saved data keeps working after an icon set update.

final icon = IconSearchService.findByName(savedName) ?? LucideIcons.circleQuestionMark;

Renamed icons also keep deprecated constants (e.g. LucideIcons.smile), so existing code still compiles and the analyzer points you at the new name.

Regenerating the icon data

lib/src/gen/lucide_icons.g.dart is generated from Lucide's published source:

dart run tool/generate_lucide_icons.dart            # all icons, from GitHub
dart run tool/generate_lucide_icons.dart --source=<lucide checkout>

A weekly GitHub Action opens an issue when upstream Lucide has changed.
