Add item at first position of list dart

You can use List.insert() method to insert an item at 0 index of the list. We need to pass the index and the item as a parameter to the List.insert() method.

List<String> subjects = ["math", "physics", "chemistry"];
subjects.insert(0, "english");
print(subjects);

Output

["english", "math", "physics", "chemistry"]

In the above code, we have a list of named subjects that contains subject names. We want to add a new subject name to the first position of this dart list. We are using the below code syntax to insert the item at the beginning of the list.

subjects.insert(0, "english");

//Syntax
List.insert(index, item)

Another method to add item to the beginning of dart list

List<String> cars = ["Volvo", "TATA", "Hyundai"];
cars = ["Audi", ...cars];
print(cars);
// -> [Audi, Volvo, TATA, Hyundai]

You can use ... to add an item to the first position of a list using the Dart programming language. In the above code, we have a list named cars and we want to add a new car name to this list. We are adding them by assigning a new list to the cars list.

Another method to add item at 0 index in a dart list

List<String> _fruits = ["Apple", "Banana", "Orange"];
  
_fruits = ["Papaya", for (String fruit in _fruits) fruit];
print(_fruits);
// -> [Papaya, Apple, Banana, Orange]

You can also use the above code to insert a new element at the beginning of a dart list.
