Methods

chat({required String apiKey, required String model, required ChatRequest request}) → Future<String>

Multi-turn. Returns the assistant's raw text for the final turn.

override

complete({required String apiKey, required String model, required String system, required String user, double temperature = 0.3, int maxTokens = 2048}) → Future<String>

Single-shot. Returns the assistant's raw text.

override

listModels(String apiKey) → Future<List<String>>

Models suitable for chat / completion, newest first. Returns an empty list for an unset / invalid key. Each provider filters out embeddings / vision / audio-only models so the dropdown isn't flooded with irrelevant entries.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

stream({required String apiKey, required String model, required ChatRequest request}) → Stream<String>

Token-streaming chat. Each event is an incremental delta — concatenating every event yields the same string chat would return. Closes the stream cleanly on end-of-message; errors are surfaced via the stream.

override

toString() → String

A string representation of this object.
