http send body and header in flutter code example

Example 1: flutter http.post headers

Future<dynamic> get(String url) async {
    //Pass headers below 
    return http.post(url, headers: {"Authorization": "Some token"}).then(
        (http.Response response) {
      final int statusCode = response.statusCode;
      LogUtils.d("====response ${response.body.toString()}");

      if (statusCode < 200 || statusCode >= 400 || json == null) {
        throw new ApiException(jsonDecode(response.body)["message"]);
      }
      return _decoder.convert(response.body);
    });
  }

Example 2: can we send raw json in get method in flutter

final queryParameters = {
  'name': 'Bob',
  'age': '87',
};
final uri = Uri.http('www.example.com', '/path', queryParameters);
final headers = {HttpHeaders.contentTypeHeader: 'application/json'};
final response = await http.get(uri, headers: headers);
