Kotlin flow to list

Kotlin flows on Android. In coroutines, a flow is a type that can emit multiple values sequentially, as opposed to suspend functions that return only a single value. For example, you can use a flow to receive live updates from a database. Flows are built on top of coroutines and can provide multiple values. A flow is conceptually a stream of ...

Consider you have a list of objects, all with a nullable property, and you want to get the first non-null value of that property in the collection. Usually, you would first use mapNotNull () to get a collection of all non-null values and then call firstOrNull () to get the final value. In Kotlin 1.5 we have functions firstNotNullOf () and ...
While loops. while and do-while loops execute their body continuously while their condition is satisfied. The difference between them is the condition checking time: while checks the condition and, if it's satisfied, executes the body and then returns to the condition check.. do-while executes the body and then checks the condition. If it's satisfied, the loop repeats.

StateFlow is like a way to use Kotlin Flow to manage and represent a state in an application. StateFlow is a type of interface, which is only a read-only and always returns the updated value. And to receive the updated value we just collect the value from the implemented Flow. StateFlow only returns if the value has updated and doesn't return ...
Kotlin Flow is one of the latest addition to the Kotlin Coroutines. With Kotlin Flow we can handle streams of data asynchronously which is being executed sequentially. What are we going to build in this article? We will build a simple app that fetches some data from API and shows it on the screen.
Functional programming (often abbreviated as FP) is the process of building software by composing pure function, avoiding shared state, and mutable data. Functional programming is declarative rather than imperative, and the application state flows through pure functions. Functional code tends to be more concise, more predictable, and easier to ...
