Unable to add header for post method in dio in Flutter

I'm using dio: ^3.0.4. Any one please help me to find the solution for adding header. here my code:

FormData formData = 
    new FormData.fromMap({"files": await MultipartFile.fromFile(filePath.path, filename: 'photo')
          });

  Response response = await dio.post("***********",
    data: formData,
    onSendProgress: (int sent, int total) {
      print("$sent $total");
    },
    options: Options(
      headers: {
        "authorization": "*************"
      },
      followRedirects: false,
      validateStatus: (status) {
        return status <= 500;
      }
    ),
  );

When i print the header.

print(response.headers);

Result:

flutter: content-type: text/html; charset=UTF-8 connection: close cache-control: no-cache, private transfer-encoding: chunked date: Thu, 07 Nov 2019 14:29:02 GMT server: Apache/2.4.18

I'm using it like this:

_dio = Dio();
_dio.options.baseUrl = _baseUrl;
_dio.options.connectTimeout = 5000; //5s
_dio.options.receiveTimeout = 3000;
_dio.options.contentType = 'application/json';
_dio.options.headers['Content-Type'] = 'application/json';
_dio.options.headers["Authorization"] = "Bearer 284|NRx1PaEY2HbwHi2XMzGdxg9UJ5rGXkNMcYyNXkqH";
_dio.options.followRedirects = false;
_dio.options.validateStatus = (status) {
  return status! < 500;
};

In case of you use di in your projects and the dioclient is a singleton, this is how authorization is added to the call.

final response = await _dioClient.get(Endpoints.getDashboard,
          queryParameters{'shopId':int.parse(shopId)},
          options: Options(
            headers: {
              "authorization": "Bearer <your token>",
            },
          ),
        );

dio.options.contentType = ContentType("application","x-www-form-urlencoded") as String;

That's probably bug because I was not able to set it with lowercase content-type.

Content-Type works.

options.headers = {'Content-Type': 'application/json', ...request.headers};

Feel free to refer to https://github.com/flutterchina/dio/issues/1045

    Dio dio = new Dio();
    dio.options.contentType = ContentType("application","x-www-form-urlencoded");
    dio.options.headers[HttpHeaders.authorizationHeader] ="Basic $clientCredentials";

Dio library key working perfectly fine in my case if we pass small case key value

For example,

Dio dio = new Dio();
dio.options.headers['content-Type'] = 'application/json';
dio.options.headers["authorization"] = "token ${token}";
response = await dio.post(url, data: data);

make sure you write key in small case, that's work for me.

There are some similar questions do not have answer
But the following work for me
Please use the following code snippet to set headers attribute

  Dio dio = new Dio();
  dio.options.headers["Authorization"] = "Bearer ${token}";
  response = await dio.post(url, data: data);
