如何将梯度颜色作为颤音中的kgradientColor？

Question

我刚刚创建了const颜色，我想要梯度颜色的const。 如果有人知道，请帮助我。

const bgcolor = Color(0xFFF6F6F6);
const fontColor = Color(0xFF151515);
const fontparaColor = Color(0xFF8B8B8B);
const iconOnTapColor = Color(0xFF8B8B8B);
const iconColor = Color(0xFF1F7CFE);
const buttonBgColor = Color(0xFF016AFF);
const diverColor = Color(0xFFB9B9B9);
const buttonTextColor = Color(0xFFFFFFFF);
const hintTextColor = Color(0xFFB3B3B3);
const fontWeight = FontWeight.w500;
