## <ApiType type="Attribute" path="core/google/dynamic_config" symbolName="GoogleDynamicConfig" /> GoogleDynamicConfig
**Type:** <TypeLink type={{"type_str": "BaseDynamicConfig[ContentListUnion | ContentListUnionDict | BaseMessageParam, GoogleCallParams, Client]", "description": null, "kind": "generic", "base_type": {"type_str": "BaseDynamicConfig", "description": null, "kind": "simple", "doc_url": "/docs/v1/api/core/base/dynamic_config#basedynamicconfig"}, "parameters": [{"type_str": "ContentListUnion | ContentListUnionDict | BaseMessageParam", "description": null, "kind": "union", "base_type": {"type_str": "Union", "description": null, "kind": "simple", "doc_url": "https://docs.python.org/3/library/typing.html#typing.Union"}, "parameters": [{"type_str": "ContentListUnion", "description": null, "kind": "simple", "doc_identifier": "ContentListUnion"}, {"type_str": "ContentListUnionDict", "description": null, "kind": "simple", "doc_identifier": "ContentListUnionDict"}, {"type_str": "BaseMessageParam", "description": null, "kind": "simple", "doc_url": "/docs/v1/api/core/base/message_param#basemessageparam"}]}, {"type_str": "GoogleCallParams", "description": null, "kind": "simple", "doc_url": "/docs/v1/api/core/google/call_params#googlecallparams"}, {"type_str": "Client", "description": null, "kind": "simple", "doc_identifier": "Client"}]}} />
The function return type for functions wrapped with the `google_call` decorator.
Example:
```python
from mirascope.core import prompt_template
from mirascope.core.google import GoogleDynamicConfig, google_call
@google_call("google-1.5-flash")
@prompt_template("Recommend a {capitalized_genre} book")
def recommend_book(genre: str) -> GoogleDynamicConfig:
return {"computed_fields": {"capitalized_genre": genre.capitalize()}}
```
