Nullability in Android 11
The nullability feature has been baked into Android 11’s type system. When declaring a reference, users say upfront whether it can hold null values.

“This aspect of Kotlin makes your code safer — if you later call a method or try to access a property on a non-null variable like x, you know you’re not risking a null pointer exception,” Android wrote in a post, which explains the feature in greater detail. “We hear over and over again that this feature of Kotlin gives developers more peace of mind and leads to higher quality apps for end-users.”

The @Nullable annotation ensures that when using the result of getCurrentName in a Kotlin file, you can’t dereference it without a null check.
