url method

@override Uri url(List<String> scopes, String state, { String duration = 'permanent', bool compactLogin = false, })

Generates the authentication URL used for Reddit user verification in a browser.

scopes is the list of all scopes that can be requested (see https://www.reddit.com/api/v1/scopes for a list of valid scopes). state should be a unique String for the current Authenticator instance. The value of state will be returned via the redirect Uri and should be verified against the original value of state to ensure the app access response corresponds to the correct request. duration indicates whether or not a permanent token is needed for the client, and can take the value of either 'permanent' (default) or 'temporary'. If compactLogin is true, then the Uri will link to a mobile-friendly Reddit authentication screen.

Implementation

@override
Uri url(List<String> scopes, String state,
    {String duration = 'permanent', bool compactLogin = false}) {
  // TODO(bkonyi) do we want to add the [implicit] flag to the argument list?
  var redditAuthUri =
      _grant.getAuthorizationUrl(_redirect, scopes: scopes, state: state);
  // getAuthorizationUrl returns a Uri which is missing the duration field, so
  // we need to add it here.
  final queryParameters =
      Map<String, dynamic>.from(redditAuthUri.queryParameters);
  queryParameters[_kDurationKey] = duration;
  redditAuthUri = redditAuthUri.replace(queryParameters: queryParameters);
  if (compactLogin) {
    var path = redditAuthUri.path;
    path = path.substring(0, path.length) + r'.compact';
    redditAuthUri = redditAuthUri.replace(path: path);
  }
  return redditAuthUri;
