BoldifyIcon class
A graphical icon widget drawn with a glyph from a font described in an IconData, similar to Flutter’s built-in Icon, but with an extra fontWeight property to allow rendering bold icons or matching the weight of surrounding text.
This is useful when:
- You want to make icons visually stronger to match bold text.
- You’re using a variable icon font (such as Material Symbols) and want fine control over stroke thickness alongside fill, weight, grade, and opticalSize.
All other behavior is identical to Icon:
- Honors ambient IconThemeData for size, color, opacity, and variable font settings.
- Can be flipped automatically for right-to-left layouts if IconData.matchTextDirection is true.
- Can be used anywhere an Icon is used.
The fontWeight parameter directly maps to the text rendering weight, so any FontWeight constant is valid, from FontWeight.w100 (thin) to FontWeight.w900 (black). For example, to make an icon bold:
const BoldifyIcon(
Icons.favorite,
fontWeight: FontWeight.bold,
color: Colors.red,
size: 32,
)
{@end-tool}
