Implementation

required String projectId,
}) async {
// Vertex AI endpoint for publisher models uses v1beta1 and does not have the 'projects/...' in the path
// when using this specific endpoint, but it requires the google user project header (or just works with ADC).
// The base URL for this is https://{location}-aiplatform.googleapis.com
// And path is /v1beta1/publishers/google/models
final url = 'v1beta1/publishers/google/models';
return await _call('GET', url, null, {'x-goog-user-project': projectId});
