Getting Started

fontify_plus turns a directory of SVG icons into an OpenType font and an optional Flutter IconData class.

CLI (fastest path)

dart pub global activate fontify_plus
fontify_plus assets/svg/ fonts/my_icons.otf \
  --output-class-file=lib/my_icons.dart -r

Then register the font in your Flutter pubspec.yaml:

flutter:
  fonts:
    - family: My Icons
      fonts:
        - asset: fonts/my_icons.otf

API (same pipeline in Dart)

Low-level (in-memory SVG map):

final result = svgToOtf(
  svgMap: {'arrow_up': await File('arrow_up.svg').readAsString()},
  fontName: 'My Icons',
);

writeToFile('MyIcons.otf', result.font);

final source = generateFlutterClass(
  glyphList: result.glyphList,
  familyName: result.font.familyName,
  className: 'MyIcons',
  fontFileName: 'MyIcons.otf',
);

Job API (reads SVG directories from disk, same as CLI):

runFontJob(FontJob(
  inputSvgDir: 'assets/svg',
  outputFontFile: 'fonts/my_icons.otf',
  outputClassFile: 'lib/my_icons.dart',
  className: 'MyIcons',
));

Where to go next

• API Usage — parameters on svgToOtf and generateFlutterClass.
• Variable stroke width — wght axis as literal stroke width.
• Stroked Icons — why outline-style SVGs need stroke conversion.
• Glyph Sizing — artboard mapping vs --normalize.
• CLI & Config — flags and the yaml config file.
• example/ — Flutter web app that regenerates icons with dart run tool/generate.dart and shows them in Chrome.
