first property

E first

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 => this.getValue().first;

void first=(E value)

Updates the first position of the list to contain value.

Equivalent to theList[0] = value;.

The list must be non-empty.

Implementation

set first(E value) {
  if (this.first != value) {
    this.getValue().first = value;
    listUpdated();
  }
}
