ProxyNotifier4<T, L1, L2, L3, L4> constructor

ProxyNotifier4<T, L1, L2, L3, L4>(
  1. L1 l1,
  2. L2 l2,
  3. L3 l3,
  4. L4 l4,
  5. T getValue(
    1. L1 l1,
    2. L2 l2,
    3. L3 l3,
    4. L4 l4,
    ), {
  6. bool? concurrent = false,
})

Transforms four values into a ValueListenable.

At least 1 of these four values should be a Listenable, so that the ProxyNotifier knows when to send its own notifications.

Implementation

ProxyNotifier4(this.l1, this.l2, this.l3, this.l4, this.getValue, {super.concurrent})
  : super(ProxyListenable(l1, l2, l3, l4), value: getValue(l1, l2, l3, l4));
