Flutter - Server Not Seeing UserAgent in Get Request - flutter

Question

I am sending get requests in a flutter app and my server is sending a response depending on data from the phones user agent, when i send a request from a native app there is no problem -
example: "Dalvik/2.1.0 (Linux; U; Android 10; Infinix X655C Build/QP1A.190711.020)"
but when i do the same from my flutter app on an android phone the sever sees something else.
example: "Dart/2.16 (dart:io)"
this is happening even though the get request has the headers property in the request
this is the flutter code:
Future<bool> approvedData() async {
var serverUrl = "https://appsofksenia.com/app_data";
String userAgent = await FlutterUserAgent.getPropertyAsync('userAgent');
Map<String, String> headers = {
HttpHeaders.authorizationHeader: 'Basic $userAgent',
'Content-Type': 'application/json; charset=UTF-8',
'Accept': 'application/json',
"User-Agent": userAgent,
};
http.Response res = await http.get(Uri.parse(serverUrl),headers: headers);
if(res.statusCode == 200){
if(res.body.isNotEmpty) {
dynamic response = json.decode(res.body);
var serverResponse = PrivacyResponse.fromJson(response);
var serverAnswer = serverResponse.privacy;
if (serverAnswer == "data_change") {
return true;
} else {
return false;
}
}else{
return false;
}
}else{
return false;
}
}
debug of the flutter app

I solved it by using the fk_user_agent library: https://pub.dev/packages/fk_user_agent
You can make a method like this:
Future<String> getUserAgent() async {
try {
await FkUserAgent.init();
var platformVersion = FkUserAgent.userAgent!;
return platformVersion;
} on PlatformException {
return "";
}
}
Then send the return value with the key "user-agent" in the headers Map.
