elk_stroke_icons 0.1.1

Lucide icons for Flutter with no fonts or SVG assets: drawn with CustomPainter from generated Dart data, with search and rename-safe name lookup.

elk_stroke_icons

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
data	Required. The icon data to render (e.g., LucideIcons.house)	-
size	The size of the icon	24
color	The color of the icon's stroke	IconTheme.of(context).color
strokeWidth	The width of the icon's stroke	2.0
rounded	Whether to use rounded stroke caps and joins	true

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.
