executeGenericRequest<T extends ISerializable<T>> method

Future<T?> executeGenericRequest<T extends ISerializable<T>>({ required T typeResolver, required HttpMethod method, required Uri uri, dynamic body, })

Executes a generic request with authentication to the specified Uri with specified HttpMethod and with the specified body (if any)

returns response data as T type which is specified as a generic type parameter to the function.
