public @interface Nullable
```
A common annotation to declare that annotated elements can be null.
Leverages JSR-305 meta-annotations to indicate nullability in Java to common tools with JSR-305 support and used by Kotlin to infer nullability.
Should be used at parameter, return value, and field level. Methods override should repeat parent @Nullable annotations unless they behave differently.
Can be used in association with @NonNullApi to override the default non-nullable semantic to nullable.
