get method

T get()

Gets the current value of the signal.

If the signal is dirty, updates it first. Automatically establishes a dependency relationship with the active subscriber if one exists.

Returns the current committed value.

  if ((flags & ReactiveFlags.dirty) != ReactiveFlags.none) {
    if (didUpdate()) {

      }
    }
  }

    if (
      (sub.flags & 3 /*(ReactiveFlags.mutable | ReactiveFlags.watching)*/ ) !=
      ReactiveFlags.none
    ) { // dart format on
      link(this, sub, cycle);
      break;
    }
