flutter/engine#31530 introduced some nullability annotations, and one of them seems wrong to me and when using Kotlin, it breaks the code which is using nulls, because those annotations are enforced by Kotlin compiler.

The value parameter should be @Nullable. The next line that immediately checks for it to be null is an indicator of that.
