FontLoader class

Registry for font files used in pure Dart text rendering.

Since pure_ui runs outside of Flutter, there is no system font registry. Use FontLoader to register TTF/OTF font files by family name before rendering text with ParagraphBuilder.

Example:

// Register from raw bytes
final bytes = File('/path/to/Roboto-Regular.ttf').readAsBytesSync();
FontLoader.load('Roboto', bytes);

// Register from a file path
FontLoader.loadFromFile('Roboto', '/path/to/Roboto-Bold.ttf',
  weight: FontWeight.bold);

// Then use in paragraph building
final builder = ParagraphBuilder(ParagraphStyle(fontFamily: 'Roboto'));
builder.addText('Hello');
