Implementation

Future<void> addImageFromIconData({
  required String id,
  required IconData iconData,
  int size = 200,
  Color color = const Color(0xFF000000),
}) async {
  await addImageFromCanvas(
    id: id,
    width: size,
    height: size,
    painter: (canvas) {
      TextPainter(textDirection: TextDirection.ltr)
        ..text = TextSpan(
          text: String.fromCharCode(iconData.codePoint),
          style: TextStyle(
            letterSpacing: 0,
            fontSize: size.toDouble(),
            fontFamily: iconData.fontFamily,
            package: iconData.fontPackage,
            color: color,
          ),
        )
        ..layout()
        ..paint(canvas, Offset.zero);
    },
  );
