getWellknownSupport method
Gets server admin contact and support page of the domain.
NOTE:
Like the well-known discovery URI,
this endpoint should be accessed with the hostname of the homeserver's
server name by making a
GET request to https://hostname/.well-known/matrix/support.
Note that this endpoint is not necessarily handled by the homeserver. It may be served by another webserver, used for discovering support information for the homeserver.
Implementation
Future<GetWellknownSupportResponse> getWellknownSupport() async {
  final requestUri = Uri(path: '.well-known/matrix/support');
  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 GetWellknownSupportResponse.fromJson(json as Map<String, Object?>);
