SetSignal

Set signals can be created by extension or method and implement the Set interface.

This makes them useful for creating signals from existing sets, or for creating signals that can be used as sets.

setSignal, SetSignal

final s = setSignal({1, 2, 3});

toSignal()

final s = {1, 2, 3}.toSignal();

Methods

Set modifications are done directly on the underlying set and will trigger signals as expected.

final s1 = setSignal({1, 2, 3});

// mutations
s1.add(4);
s1.remove(2);

// expose common Dart Set interfaces
s1.length;                   // 3
s1.contains(3);              // true
s1.intersection({6, 2, 1});  // {1}
