uploadContent method

Future<Uri> uploadContent(Uint8List body, { String? filename, String? contentType, })

filename The name of the file being uploaded

body

contentType Optional. The content type of the file being uploaded.

Clients SHOULD always supply this header.

Defaults to application/octet-stream if it is not set.

returns content_uri: The mxc:// URI to the uploaded content.

Implementation

Future<Uri> uploadContent(
  Uint8List body, {
  String? filename,
  String? contentType,
}) async {
  final requestUri = Uri(
    path: '_matrix/media/v3/upload',
    queryParameters: {
      if (filename != null) 'filename': filename,
    },
  );
  final request = Request('POST', baseUri!.resolveUri(requestUri));
  request.headers['authorization'] = 'Bearer ${bearerToken!}';
  if (contentType != null) request.headers['content-type'] = contentType;
  request.bodyBytes = body;
  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['content_uri'] as String).startsWith('mxc://')
      ? Uri.parse(json['content_uri'] as String)
      : throw Exception('Uri not an mxc URI'));
