#9 - Understanding Null Safety in Dart - Type Promotions, Null Assertion, Late, Required
Hi there!
In this video I'll show you a complete and really in-depth in what I believe it's probably the most important addition to the Dart Language, and that is, null safety. In this tutorial you'll learn why null safety was introduced in the first place, what changes it does bring, what are type promotions, how to declare a nullable field, and many other more interesting topics on how to use the null assertion operator, the late and required keyword.
