Append Item In Array In Dart

Dart, the programming language developed by Google, is gaining much attention for its robustness, scalability and ease of use. It is used frequently in developing mobile, desktop, server, and web applications. This article will show you how to append an item in an array in Dart with a simple code snippet and detailed explanation.

Code snippet for append item in array in Dart

void main() {
    List<int> numArray = [1, 2, 3, 4, 5];
    numArray.add(6);
    print(numArray);
}

Code Explanation for appending an item in an array in Dart

In Dart, the arrays are as List objects, so they provide several functionalities out-of-the-box, such as appending an item.

In the code snippet above, we begin by defining a function named main. This function serves as the starting point for the program.

Initializing a List of integers called numArray is our next step. It is initialized with the values [1, 2, 3, 4, 5].

We then use the add method, which is a built-in method provided by Dart for adding an item to a list. In this case, we are adding the integer ‘6’ to the list numArray.

Finally, we print the list to the console with the print statement. The output will be:

[1, 2, 3, 4, 5, 6]

This is the original list, with the integer ‘6’ appended to its end.

So, we have learned how to append an item to an array (list) in Dart. This simple task is very common in programming, specially while processing and managing data. Understanding the basics of List manipulation in Dart can provide a solid foundation for solving more complex programming problems.
