Нарисуйте сложный элемент во Flutter с путем, а затем перерисуйте этот же элемент под разными углами

Форма представляет собой прямоугольник с закругленными краями. Вы можете использовать CustomPaint. Пожалуйста, посмотрите код ниже или запустите его непосредственно на DartPad здесь >> https://dartpad.dev/e0792a6ab7c9ff3aa1516bfeb77c3886
