Dart .contains()

The .contains() method determines whether a specified element is present in a list. It returns a Boolean value of true if the element is found in the list and false if it happens otherwise.

Syntax

list.contains(element)

• list: The name of the list that needs to be searched.
• element: The element that needs to be searched.

Example

In this example, the .contains() method is used to check if the string banana is present in the fruits list:

void main() {
  List<String> fruits = ['apple', 'banana', 'orange'];

  // The .contains() method searches for the element 'banana' in the 'fruits' list
  bool containsBanana = fruits.contains('banana');

  print(containsBanana);
}
