Memory is allocated to lateinit variables only when they are initialized later in the program, rather than when they are declared.

The lateinit keyword stands for “late initialization.” When used with a class property, the lateinit modifier keeps the property from being initialized at the time of its class’ object construction.

The difference between by lazy and = lazy.

Lifecycle-driven properties and lateinit.

Examples of the lateinit modifier in use.

This will make your Kotlin development workflow more efficient altogether. This article will explain how the lateinit modifier and lazy delegation can take care of unused or unnecessary early initializations. This is another example of where lateinit can come to our rescue. What if an initialized property or object doesn’t actually get used in the program? Well, these unused initializations will be liabilities to the program since object creation is a heavy process. The IntelliJ IDEA editor will warn you if you declare a class property without initializing it and recommend adding a lateinit keyword. Luckily, there is a way to get through this problem. Doing this seems odd when we don’t know the ideal initial value, especially in the case of lifecycle-driven Android properties. Kotlin usually requires us to initialize properties as soon as we define them.
