Gradient colors can be added to SVG icons in Flutter by using the svg
package and the PathPiece
class. This class allows us to apply a gradient to the SVG paths.
First, we need to import the svg
package:
import 'package:flutter_svg/flutter_svg.dart';
Then, we can load the SVG asset and create a PathPiece
object from the SVG path:
final icon = SvgPicture.asset(
'assets/icons/my_icon.svg',
width: 24,
height: 24,
);
final pathPiece = PathPiece.parsePath(icon.pictureProvider.string);
Next, we can create a Paint
object and set its shader to a LinearGradient
:
final gradient = LinearGradient(
colors: [Colors.red, Colors.blue],
begin: Alignment.topLeft,
end: Alignment.bottomRight,
);
final paint = Paint()
..shader = gradient.createShader(pathPiece.getBounds());
Finally, we can draw the SVG path with the gradient fill:
Canvas canvas = ...; // get canvas from Paint widget or other
canvas.drawPath(
pathPiece.path,
paint,
);
