This feature is called null-safety, a group of annotations working like a safeguard that watches out for potential null references. We can use this annotation t0 declare non-null constraint anywhere an object reference is expected: a field, a method parameter or a method's return value.
Let's start with null-conditional operator - it's ?.. It's also called 'elvis-operator'. Not sure why? Have a closer look - you will see a pair of eyes with elivs like haircut. The operator lets you access members and elements only when the receiver is not-null, returning null result otherwise.
