In this blog we will discuss on how to update the values of List based on index in dart file.
Lets suppose we have an list of integers as below
```
List<int> exampleArray = [1, 2, 3];
```
To replace the Third element below is the syntax.
```
exampleArray[2] = 9;
```
As the index starts from 0 we specify the index as 2 to get the 3 rd element.

Below is the example program of modifying the List.

void main() {
List<int> exampleArray = [1, 2, 3];
exampleArray[2] = 9;
print(exampleArray);
}

Output:

[1, 2, 9]
