By using the lazy function, the code now compiles. Data Binding and Kotlin are two popular features in Android development that can greatly simplify the process of building a user interface. ![]() It is a very powerful pattern to delegate loading an object, so Kotlin includes a function, lazy, to facilitate lazy loading. The compiler would not allow a mutable object to be returned when the method signature was expecting an immutable object. Yikes! companion object Īfter the converter attempted to convert this pattern, the code would not compile since it made list immutable, yet the return type of createMovies() was mutable.
