Implementation

Future<bool> registrationTokenValidity(String token) async {
  final requestUri = Uri(
      path: '_matrix/client/v1/register/m.login.registration_token/validity',
      queryParameters: {
        'token': token,
      });
  final request = Request('GET', baseUri!.resolveUri(requestUri));
  final response = await httpClient.send(request);
  final responseBody = await response.stream.toBytes();
  if (response.statusCode != 200) unexpectedResponse(response, responseBody);
  final responseString = utf8.decode(responseBody);
  final json = jsonDecode(responseString);
  return json['valid'] as bool;
