Understanding Null Safety: Kotlin Fundamentals Tutorial - Part
In this video we explore the null safety in a very detailed manner. Kotlin allows us to declare a data type as nullable. All you have do is put "?" when you provide the data type while declaring a variable. With that option on, we basically allow the variable to be assigned a null value. Other than that if you want to invoke any method on such variable, we have to just out ? in front if that variable. Kotlin provides other operators also associated with null safety - not null assertion, elvis operator. Explore all of that in detailed manner in this video.
