Why do we remove the if? If the value for hasClip hasn't changed, why does it need to run invalidate()?
Does it actually need to be called in a different place in the stack? In .NET MAUI's C# layer, perhaps it would know what changed?

@jonathanpeppers I've just done what you asked: revert your PR and use invalidate instead of postInvalidate.
That said:
- setting a boolean field value has very likely no impact on performance, so the
ifis kind-of useless - this method is being called from the C# layer when the
Clipchanges, that's why we always need to invalidate- calling it from C# would cause two JNI roundtrips for nothing

Setting the field isn't the question, but the fact that invalidate() is called. Why do we need call invalidate() if true is set to true? or false set to false?

Because the clip path or the shadow details like color, radius,... have changed.

we should call these methods something like invalidateShadow(bool willDrawShadow) but it's a public API and I can't do that

If the clip path or shadow changes, should those be the things that call invalidate()?

The reason to not move invalidate call there is just to avoid two round trips on JNI. So this is just a naming problem in my opinion.

Description of Change
#24222 broke reaction to shadow / clip changes.
This PR brings back the original code while replacing
postInvalidatewithinvalidateto avoid countless scheduled invalidations considering that MAUI only operates on platform views through the main thread.You can see more details in the issue's comments.
While CI regenerates the
aar, we should commit the newaaronce this is merged, or as part of this PR.I've not included it for security reasons.
