get method
Gets information about an access token issued by a user.
Request parameters:
userKey - Identifies the user in the API request. The value can be the
user's primary email address, alias email address, or unique user ID.
clientId - The Client ID of the application the token is issued to.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a Token.
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<Token> get(
  core.String userKey,
  core.String clientId, {
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'admin/directory/v1/users/' +
      commons.escapeVariable('$userKey') +
      '/tokens/' +
      commons.escapeVariable('$clientId');
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return Token.fromJson(response_ as core.Map<core.String, core.dynamic>);
