fetch method

Future<FetchRemoteConfigResponse> fetch(FetchRemoteConfigRequest request, String project, String namespace, { String? $fields, })

Fetch parameter values and any Firebase A/B Testing experiment information for the calling device.

An ETag header is also returned. Pass the ETag in future requests via the If-None-Match header to save bandwidth. NOTE: The Fetch REST API requires an Instance ID to be populated in the request. The Instance ID can obtained from the IID SDK. See https://firebase.google.com/docs/reference/android/com/google/firebase/iid/FirebaseInstanceId and https://firebase.google.com/docs/reference/ios/firebaseinstanceid/api/reference/Classes/FIRInstanceID

request - The metadata request object.

Request parameters:

project - Required. The Firebase project ID or project number. (NOTE: These identifiers can be retrieved from the Firebase console.)

namespace - Required. The string "firebase".

$fields - Selector specifying which fields to include in a partial response.

Completes with a FetchRemoteConfigResponse.

Completes with a commons.ApiRequestError if the API endpoint returned an error.

If the used http.Client completes with an error when making a REST call, this method will complete with the same error.

Implementation

async.Future<FetchRemoteConfigResponse> fetch(
  FetchRemoteConfigRequest request,
  core.String project,
  core.String namespace, {
  core.String? $fields,
}) async {
  final _body = convert.json.encode(request);
  final _queryParams = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };

  final _url = 'v1/projects/' +
      commons.escapeVariable('$project') +
      '/namespaces/' +
      commons.escapeVariable('$namespace') +
      ':fetch';

  final _response = await _requester.request(
    _url,
    'POST',
    body: _body,
    queryParams: _queryParams,
  );
  return FetchRemoteConfigResponse.fromJson(
      _response as core.Map<core.String, core.dynamic>);
}
