# isSingleton abstract method

Future<bool> isSingleton(

1. String podName

)

Checks if the specified pod is configured as a singleton.

Singleton pods are instantiated only once and the same instance is returned for all subsequent requests.

## Usage Example:

    if (await factory.isSingleton('appConfig')) {
      print('AppConfig is a singleton - all components share the same instance');
    }

@param podName The name of the pod to check @return A Future that completes with true if the pod is a singleton

## Implementation

    Future<bool> isSingleton(String podName);
