chatFallbackFor method
Chat model ids the catalog knows about for providerKind — the
LAST-RESORT fallback the picker uses when the live /v1/models
fetch is empty. Endpoint-reported ids always win; this list is
only consulted on the empty-result branch so the picker stays
useful when the endpoint can't answer.
Implementation
List<String> chatFallbackFor(String? providerKind) {
return remoteChatModelsFor(providerKind: providerKind, catalog: _cached);
}
