Merge Two Arrays Together In Dart

Merging two arrays together in Dart is a simple and straightforward process. This article is specifically tailored to provide an easy-to-follow guide on how to achieve this.

Code snippet for Merging Two Arrays in Dart

The following code snippet demonstrates how you can merge two arrays in Dart:

void main() {
  List<int> list1 = [1, 2, 3];
  List<int> list2 = [4, 5, 6];
  
  list1.addAll(list2);

  print(list1);
}

This script will output:

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

This indicates that the two arrays list1 and list2 have been successfully merged together.

Code Explanation for Merging Two Arrays in Dart

Here is a step-by-step explanation of what the provided Dart code does:

Step 1: Define two lists, list1 and list2 with some elements.

List<int> list1 = [1, 2, 3];
List<int> list2 = [4, 5, 6];

Step 2: Use the addAll method.

This method allows you to append all elements from another list directly to the first list:

list1.addAll(list2);

After the execution of this line, list1 will contain all of its initial elements in addition to all the elements of list2.

Step 3: Then, print the merged list:

print(list1);

This will output the elements of the merged list.

The above-recommended method is effortless and efficient for merging or appending two lists in Dart. The principle can be applied to lists of varying data types. Remember, arrays in Dart are referred to as lists.
