ToolCall({required String id, required String name, required Map<String, dynamic> arguments, String? parentCallId, String? thoughtSignature, String? partialArguments}): const
ToolCall.fromJson(Map<String, dynamic> json): Deserializes from a JSON map produced by toJson.

arguments → Map<String, dynamic>: Parsed tool arguments. Empty while the call is still streaming; see partialArguments.
final
hashCode → int: The hash code for this object.

id → String: Provider-assigned tool call id (matched by the tool result message).
final
name → String: Name of the tool to invoke.
final
parentCallId → String?: Id of the enclosing tool call for nested (subtool) executions, or null for a top-level call.
final
partialArguments → String?: Raw, not-yet-complete JSON argument text accumulated from ToolCallDeltaEvents. Providers keep the live partial message's tool call block up to date with this; on ToolCallEndEvent the completed JSON is parsed into arguments. null once parsing succeeded.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
thoughtSignature → String?: Google-specific opaque signature for reusing thought context.
