remainingCacheExtent property Null safety

double remainingCacheExtent
final

Describes how much content the sliver should provide starting from the cacheOrigin.

Not all content in the remainingCacheExtent will be visible as some of it might fall into the cache area of the viewport.

Each sliver should start laying out content at the cacheOrigin and try to provide as much content as the remainingCacheExtent allows.

The remainingCacheExtent is always larger or equal to the remainingPaintExtent. Content, that falls in the remainingCacheExtent, but is outside of the remainingPaintExtent is currently not visible in the viewport.
