# destroySingletons method

void destroySingletons()
inherited

Destroy all singleton pods in this registry.

This method performs complete registry shutdown by:

- Destroying all singletons in reverse registration order
- Cleaning up all internal state
- Handling proper destruction order based on dependencies

Example:

    // During application shutdown
    registry.destroySingletons();

## Implementation

    void destroySingletons() {
      synchronized(_singletons, () => _singletonsCurrentlyInDestruction = true);

      final names = List<String>.from(_disposablePods.keys);
      for (int i = names.length - 1; i >= 0; i--) {
        destroySingleton(names[i]);
      }

      _containedPods.clear();
      _dependentPods.clear();
      _dependenciesForPods.clear();

      clearSingletonCache();

      return synchronized(_singletons, () => _singletonsCurrentlyInDestruction = true);
    }
