Implementation

http.Request prepareHttpRequest({
  required Uri url,
  required String method,
  required Map<String, String> headers,
  required String? body,
  bool overrideContentType = false,
}) {
  var request = http.Request(method, url);
  if (headers.getValueContentType() != null) {
    request.headers[HttpHeaders.contentTypeHeader] = headers
        .getValueContentType()!;
    if (!overrideContentType) {
      headers.removeKeyContentType();
    }
  }
  if (body != null) {
    request.body = body;
    headers[HttpHeaders.contentLengthHeader] = request.bodyBytes.length
        .toString();
  }
  request.headers.addAll(headers);
