In continuation to previous my previous blogs, where we learnt about how can we use AndroidJavaClass and AndroidJavaObject to achieve simple native Android functionality in Unity, We will move one step ahead and see how can we typecast one Android object to another in Unity.

After reading my last blog about Kotlin with function, a lot of developers have asked me about, why with is not an extension to Template class like other scope functions?

Not only with, but run also has two implementations among which one is not an extension to Template class but a generic extension function.

The question is why?

with is an extension to generic class means it is not specific to any class. This could have been an extension to Any class which is the base class for all…

Kotlin has made our life very easy by providing features like extension functions, nullability check and much more. One such kind of really helpful feature is Scope functions. Once you understand what scope functions are, you will not able to resist yourself from using them.

In continuation to my previous post where I explained about Kotlin let function and Kotlin apply function, let’s try to understand today about also function today.

There are a few scope functions

• let
• with
• run
• apply
• also

To keep this article short and to the point, we will talk only about also in this article and all the use cases around it.

also is used to perform some actions on the object and returns the object itself. A reference to the calling object is available…

It is a very common use case where we want to return two values from a method, can be either of same data type or can be of different data types. What usually we do there is either create some local variables if the method is of the same class and set those variables from the method and consume them in the place where needed or we create a struct with just two variables and return that struct object from the method.

This approach works…

Collections in any language is an interface that stores similar data type objects and provides an iteration functionality. The common extensions of Collection are List and Set.

The Map is a well-known data structure used to store key-value pairs where keys will be unique.

We can take a reference of any language but let’s look at the example of Java for reference as Collection Framework from Java is very popular.

Java has Iterable interface which is extended by Collection. The Collection is further extended by…

Collections are a common concept for most programming languages. It is a way of storing similar data types in a single object and iterate over it. Similar to any other language, Kotlin also has Collection defined in kotlin.collections package.

Types of Collection in Kotlin

There are two types of collection in Kotlin

1. Immutable
   The one which can’t be modified once the object is created. We can just iterate over them or create a copy of them but we can’t modify the actual one.
2. Mutable
   These can be modified means that we…
