functionCallingMode property

GoogleFunctionCallingMode? functionCallingMode

Controls how the model decides when to call functions.

• GoogleFunctionCallingMode.auto (default): Model decides whether to call a function or give a natural language response.
• GoogleFunctionCallingMode.any: Model is constrained to always predict a function call. Use with allowedFunctionNames to limit which functions can be called.
• GoogleFunctionCallingMode.none: Model will not predict any function calls, behaves as if no functions were provided.
• GoogleFunctionCallingMode.validated: Like auto but validates function calls with constrained decoding.

Example:

GoogleChatModelOptions(
  functionCallingMode: GoogleFunctionCallingMode.any,
  allowedFunctionNames: ['get_weather', 'get_forecast'],
)

Implementation

final GoogleFunctionCallingMode? functionCallingMode;
