watch method

T watch(
  1. BuildContext context
)

Subscribes the current BuildContext (widget) to this computed value.

The widget will automatically rebuild whenever this computed value changes. Returns the current computed value (or its scope override).

Implementation

T watch(BuildContext context) {
  final resolved = SignalScope.get(context, this);
  _watchNode(context as Element, resolved);
  return resolved.value;
}
