When is shouldRepaint method from custom painter class in flutter called. It’s possible that the paint method will get called even if shouldRepaint returns false (e.g. if an ancestor or descendant needed to be repainted). It’s also possible that the paint method will get called without shouldRepaint being called at all (e.g. if the box changes size)
bool shouldRepaint(MyPainter oldDelegate) =>
oldDelegate.completePercent != completePercent;
