How to Insert an Element at Specific Index in a List in Dart ?

To insert an element at a specific index in a list in Dart, you can use the insert method of the List class.

In this example,

We create a list named numbers with initial integer values.
We use the insert method to insert a new element at the desired index.
The insert method shifts the existing elements to the right to make space for the new element.
Finally, we print the updated list to standard output.

void main() {
  List<int> numbers = [1, 2, 3, 4, 5];
  numbers.insert(2, 10);
  print('Updated list: \$numbers');
}

Updated list: [1, 2, 10, 3, 4, 5]

In this example,

We create a list named numbers with initial integer values.
We use the insert method to insert a new element at the beginning of the list.
Finally, we print the updated list to standard output.

void main() {
  List<int> numbers = [1, 2, 3, 4, 5];
  numbers.insert(0, 10);
