getProvider<T> abstract method

Retrieves a provider for a pod, allowing for lazy or eager initialization.

A provider gives more control over when and how a pod is instantiated. This is useful for lazy loading or when you need to manage the lifecycle of pods more precisely.

Usage Example:

final provider = await factory.getProvider<DatabaseService>(
  'databaseService', 
  Class<DatabaseService>(),
  allowEagerInit: true,
);

// Get the instance when needed
final database = await provider.get();

@param podName The name of the pod to provide @param type The class type of the pod @param allowEagerInit Whether to allow eager initialization @return A Future that completes with an ObjectProvider for the pod
