Hi, How can I make an image with gradient colors?

[xiaolouxinyue]

void clear([Color? color]) => data?.clear(color);
The api of clear do not support gradient colors, is there any way to achieve this?
Thanks

eg:
LinearGradient(begin: Alignment.topCenter, end: Alignment.bottomCenter, colors: [Color(0xFFBFBBBB), Color(0xFFFFFFFF)]),
