In this blog we will discuss on how to initalize and add elements in List.
List stores elements of similar type.
Below is the syntax of declaration of List.
```
List<E> exampleArray;
```
Here E means type of variable like int or string or userdefined class.
Before adding elements into List we initialize the list as below.
```
exampleArray=[];
```
Now after initializing the array to add elements we use add function.
Below is the example syntax.
```
exampleArray.add(1);
```

Below is the sample program to declare,initialize and add elements into array.

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

Output:

[1, 2, 3]
