head<T> method Null safety

Future<Response<T>> head<T>(
  1. String path,
  2. {dynamic data,
  3. Map<String, dynamic>? queryParameters,
  4. Options? options,
  5. CancelToken? cancelToken}
)

Handy method to make http HEAD request, which is a alias of dio.fetch(RequestOptions).

Implementation

Future<Response<T>> head<T>(
  String path, {
  data,
  Map<String, dynamic>? queryParameters,
  Options? options,
  CancelToken? cancelToken,
});
