addFirst method

void addFirst(
  1. E value
)

Adds value to the start of this list, extending the length by one.

The list must be growable.

final numbers = <int>[1, 2, 3];
numbers.addFirst(0);
print(numbers); // [0, 1, 2, 3]

For fixed length lists, this method throws UnsupportedError.

Implementation

void addFirst(E value) => insert(0, value);
