.remove()

The .remove() method is used to remove the first occurrence of an item from a list. It returns true if the item is present and is successfully removed. if the item is not present, it returns false.

Note: The list must be a growable list.

Syntax

list.remove(value)

• list: The name of the list to be modified.
• value: The value to be removed from the list.

Example

In the following example, the .remove() method is used to delete the first occurrence of the value 1 from the list variable:

void main() {
  List list = [2, 1, 3, 5, 1, 7];
  print('Original list : ${list}');
  bool retValue = list.remove(1);
  print('Return value of remove function : ${retValue}');
  print('New list : ${list}');
  retValue = list.remove(4);
  print('Return value of remove function : ${retValue}');
  print('New list : ${list}');
}

The above code will produce the following output:

Original list : [2, 1, 3, 5, 1, 7]
Return value of remove function : true
New list : [2, 3, 5, 1, 7]
Return value of remove function : false
New list : [2, 3, 5, 1, 7]
