SignalsObserver

You can observe all signal values in the dart application by providing an implementation of SignalsObserver:

abstract class SignalsObserver {
  void onSignalCreated(Signal instance);
  void onSignalUpdated(Signal instance, dynamic value);
  void onComputedCreated(Computed instance);
  void onComputedUpdated(Computed instance, dynamic value);
  static SignalsObserver? instance;
}

There is a prebuilt LoggingSignalsObserver for printing updates to the console.

To add the observer override the instance at the start of the application:

void main() {
    SignalsObserver.instance = LoggingSignalsObserver(); // or custom observer
    ...
}

This will have a slight performance hit since every update will be tracked via the observer. It is recommended to only set the SignalsObserver.instance in debug or profile mode.
