Add Support for google_search_retrieval Tool in Dart SDK

[nmarafo]

Description of the feature request:

I would like to request the addition of support for the google_search_retrieval tool in the Dart SDK for the generative AI models (e.g., Gemini). This feature is already available in the Python SDK, where it allows users to pass tools='google_search_retrieval' or configure it via a dictionary for dynamic information retrieval. The same functionality would greatly enhance the capabilities of the Dart SDK.

What problem are you trying to solve with this feature?

Currently, there is no built-in support in the Dart SDK to enable models to retrieve real-time information from the web, as is possible with the Python SDK. Without this functionality, Dart developers need to manually simulate retrieval by implementing custom functions or handling responses externally. This creates additional complexity and limits the SDK's ability to deliver dynamic, real-time answers directly from the model.

Any other information you'd like to share?

This feature would align the Dart SDK's capabilities with those of the Python SDK, making it more versatile and feature-complete.
Having a native implementation of google_search_retrieval would significantly simplify the workflow for developers who need real-time retrieval functionality in applications built with Dart.
If possible, please consider adding support for configuring the tool with a string (tools='google_search_retrieval') or a dictionary (to customize retrieval behavior), as done in the Python SDK.
Thank you for considering this request! Let me know if additional details or examples are needed.
