.insert()

The .insert() method in Dart inserts an element at a specified index in a list and shifts subsequent elements to the right.

Syntax

list.insert(int index, E element);

• index: The position where the element is to be inserted.
• element: The element is the value to be added.

Example

In the following example, the .insert() method is used to insert the number 3 at the second index:

void main() {
  List<int> numbers = [1, 2, 4, 5];
  print('Original list: $numbers');

  // Inserting the number 3 at index 2
  numbers.insert(2, 3);
  print('List after insertion: $numbers');
}

The output of the above example code is as follows:

Original list: [1, 2, 4, 5]
List after insertion: [1, 2, 3, 4, 5]
