Use Path rather than Rect

[Kyant0]

It will be more customizable to achieve blur effect with irregular shapes.

[chrisbanes]

This is unlikely to be achievable, as paths aren't feasible to be passed over to a Skia shader. If anyone has any ideas on how to achieve this, let me know.

We probably probably could achieve on Android this (via clipPath).

Is it achievable to use Rect + Shape?

[Kyant0]

Since I have customed shapes which can't be approximated by RoundRect

[chrisbanes]

We'd have to manually write support into the shader to support various shapes, and then include a function to determine whether a pixel is in that shape (usually copied from here). It's not impossible, but very cumbersome.

What shape are you trying to support here?

[Kyant0]

the "cut corner" shape

[Kyant0]

I only use Compose for Android, but this library is multiplatform. I think it is hard to achieve this, or are you able to provide some Android specific API?
