async/await async defines a function that returns a Future, while await waits for a Future to complete before continuing with code execution. The exceptions can be handled with try-catch when using await to handle any exceptions thrown by the Future. await should always be used inside an async function. Flutter…

async/await | Coroutines async/await simplifies asynchronous code, making it easier to read and maintain. Coroutines execute long-running tasks without blocking the main thread or freezing the UI. async launches a coroutine and returns a Deferred object; await retrieves the result. The exceptions can be handled with try/catch or onFailure to…

async/await The async keyword is used to define a function as asynchronous. Asynchronous functions return a Task object. The Task object can be used to cancel, wait for, or handle errors. It allows to write asynchronous code in a more synchronous style, without the need for completion handlers (closures). The…

final “final” variables are initialized only once and can’t be reassigned. Declaring type boosts performance. “final” methods and classes, compilation error. “final+const” creates constants. There is no “val” keyword in Flutter, the equivalent keyword is “final”. class Button { final String title; const Button({required this.title}); void push() { } } …

final Is used to prevent a class, method, or property from being overridden in a subclass. If a class is marked as “final”, no other class can inherit from it and it cannot be changed by subclassing. if a method is marked as “final”, it cannot be overridden in a…

final Is a modifier in Kotlin that can be applied to a class, function, or property, enforce encapsulation. A class with final cannot be subclassed. Applied to function or property those cannot be overridden. Default modifier. class Button { } const Declare a constant value, cannot be changed at runtime. Constant must…

In this post I will be talking about the Api and Model used in the Home view and Market view of the Binance App. Before I start cloning that App maybe you need to know what is an API. What is an API? API is the acronym for Application Programming Interface, which is a…

In this post I will be using Generics to refactor a common mistake creating a Network layer, don’t do this on your code. Before I start talking about the Network layer let's talk a little bit about generics. So what does Apple say about generics? Generic code enables you to…

In this post I will be applying three REAL use cases for Closures, these closures are used everywhere in any application. Asynchronous Callback (URLSession, DispatchQueue, DispatchGroup) Synchronous Callback (Append String, Sort) Property Callback (Network, Append String, Sort) What is a Closure? Closures are self-contained blocks of functionality that can be passed around and used…
