first property

E first
inherited

Returns the first element.

Throws a StateError if this is empty. Otherwise returns the first element in the iteration order, equivalent to this.elementAt(0).

Implementation 

E get first => delegate.first;
void first= (E element)
override

Updates the first position of the list to contain value.

Equivalent to theList[0] = value;.

The list must be non-empty.

Implementation 

@override
// TODO: Dart 2.0 requires this method to be implemented.
// ignore: override_on_non_overriding_setter
void set first(E element) {
  if (this.isEmpty) throw new RangeError.index(0, this);
  this[0] = element;
}
