Sometimes in programming, we don’t care whether a number is negative or positive — we just want to know how far it is from zero. That’s where absolute value comes in. What is Absolute Value? In simple terms, the absolute value of a number is how far it is from zero, ignoring the sign. So […]

String splitting in Dart is the process of dividing a single string into smaller parts or substrings based on a specific delimiter or condition. The split() method in Dart allows you to easily break a string into multiple elements, typically returning them as a list of substrings. Think of it like cutting a long sentence

When working with collections in Dart, you might often find yourself needing to merge or copy multiple lists, sets, or maps. Traditionally, this can require a fair bit of manual iteration and code. However, Dart provides a simple and elegant solution to this problem with the spread operator (…). The spread operator allows you to

In Dart, you can use the for keyword inside collections like Lists, Sets, and Maps to efficiently manipulate, transform, and filter data. This powerful feature allows you to generate new collections by applying rules and conditions to existing data, all within the same collection declaration. Think of it like going through a list of tasks

In Dart, the collection if is a smart and simple way to add items to a list, set, or map only when a condition is true. Instead of writing extra if statements outside a collection, Dart lets you place conditions directly inside the collection itself. This makes your code shorter and easier to understand. Let’s

In Dart, a late variable is one that you declare now but plan to fill in later. Instead of giving it a value right away, you’re saying, “I’ll set this up before I use it.” This is helpful when you want to delay the work of creating a value until the moment you actually need
