IMO: stick with let/ run and fall back to if- else when necessary. Note that I would personally not do this, because none of these custom constructs are very pleasant to read. Val person = Person().Suppose we have this code: class QuickExample ) The context of the object can be referred to as “it” or “this” which we will be understanding through examples in this article.īut before going through these examples, let’s consider a Model class “Person”įun displayInfo() = print("\n Name: $name\n " + The opposite is true of NonNull it tells the Kotlin compiler to treat the method result as a non-null type, forbidding you from assigning that result to null later in your program. So, let’s go ahead and understand these scoped functions with some examples. If you try, Android Studio will notify you of an error, and the Kotlin compiler will throw an error in your build. In Software Development, things are only better understood by implementing rather than reading. Well, what does this mean? These functions provide a way to give temporary scope to the object under consideration where specific operations can be applied to the object within the block of code, thereby, resulting in a clean and concise code. We will be discussing the following topics in this article:ĭifferentiating scoped functions with examplesīy definition, Scoped functions are functions that execute a block of code within the context of an object.
But have you ever been confused like all of them seem the same? What is the importance of each scoped function? Are we using them correctly? How can we make the best use of it? Or, Are you completely new to this topic and want to understand these scoped functions? Well, let’s dive into the article. If you have enough hands-on experience, you might be already using scope functions. Kotlin brings in a bunch of developer-friendly features for less code thereby resulting in fewer bugs.Īmong the bunch of developer-friendly features, Kotlin brings to us, “ Almost all the Android developers have now moved from using Java to Kotlin and are experiencing how simple, clean and concise the Kotlin is when compared to Java.
