For user using impeller to draw path
Impact Description
Impact when user uses impeller to draw stroke path. Without this patch they will see a one-side cap, which is not expected
Workaround
Seems no workaround.
Risk
low

yes
Validation Steps
Using impeller to draw a stroke path, and set the cap to StrokeCap.round, expected to see both side cap rendering is good.
void main() {
runApp(CustomPaint(
painter: MyPainter(),
));
}
class MyPainter extends CustomPainter {
@override
void paint(Canvas canvas, Size size) {
Paint paint = Paint()
..color = Colors.red
..strokeWidth = 20
..strokeCap = StrokeCap.round;
canvas.drawLine(const Offset(100, 100), const Offset(200, 100), paint);
}
@override
bool shouldRepaint(covariant CustomPainter oldDelegate) {
return true;
}
}
