dart:collection

cast<R> method

List<R> cast <R>()

override

Returns a view of this list as a list of R instances.

If this list contains only instances of R, all read operations will work correctly. If any operation tries to access an element that is not an instance of R, the access will throw instead.

Elements added to the list (e.g., by using add or addAll) must be instance of R to be valid arguments to the adding function, and they must be instances of E as well to be accepted by this list as well.

Typically implemented as List.castFrom<E, R>(this).

Implementation

List<R> cast<R>() => UnmodifiableListView(_source.cast<R>());
