ap<A, B> function
- ImmutableList<
B Function(A)> fns
Applies a list of functions from fns to each item in the ImmutableList.
Example:
final list = ImmutableList<int>([10, 20]);
final functions = ImmutableList<Function>([(int x) => x + 1, (int x) => x - 1]);
final applied = ap(functions)(list);
print(applied.items); // Outputs: (11, 21, 9, 19)
Implementation
ImmutableList<B> Function(ImmutableList<A>) ap<A, B>(
ImmutableList<B Function(A)> fns) =>
(ImmutableList<A> list) =>
ImmutableList(fns._items.expand((fn) => list._items.map(fn)).toList());
