Basic auth using retrofit in Flutter-CodePudding

I have a project to build an app in Flutter and I have to login using Basic Auth and retrofit for the Api requests. I have searched everywhere and I haven't found anything that can help me on how to combine these two. Nothing that I've done so far was succesful. Can anyone help me or show me documentation that can help me?

In Android We can do Basic auth like this:

// concatenate username and password with colon for authentication
        String credentials = username   ":"   password;
        // create Base64 encodet string
        final String basic =
                "Basic "   Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);

        builder.setRequestInterceptor(new RequestInterceptor() {
            @Override
            public void intercept(RequestFacade request) {
                request.addHeader("Authorization", basic);
                request.addHeader("Accept", "application/json");
            }
        });

so maybe possible we can do like this also in flutter

var auth = 'Basic ' base64Encode(utf8.encode('$username:$password'));

Future<Response> callAPI(param) async {
await dio.post('/api/test',
    data: {'param': param},
    options: Options(headers: <String, String>{'authorization': auth}));

}

You can use this code for basic request for auth.And if you want to return response, you can use something else instead of void. Like String or dynamic for return response

import 'package:http/http.dart' // import this

Future<void> sendRequest (dynamic baseUrl...)async{
 var response = await http.post(
      Uri.parse(baseUrl).replace(queryParameters: queryParameters),
      headers: header,
      body: json ?? jsonEncode(request),
    );
}
