ReadonlyReacton<T> class

A read-only reacton that derives its value from other reactons.

The value is automatically recomputed when any dependency changes. Created via the top-level computed() factory function.

final doubleCountReacton = computed(
  (read) => read(counterReacton) * 2,
  name: 'doubleCount',
);
