hijack method

Never hijack(
  1. void callback(
    1. StreamChannel<List<int>>

Takes control of the underlying request socket.

Synchronously, this throws a HijackException that indicates to the adapter that it shouldn't emit a response itself. Asynchronously, callback is called with a StreamChannel<List<int>> that provides access to the underlying request socket.

This may only be called when using a Shelf adapter that supports hijacking, such as the dart:io adapter. In addition, a given request may only be hijacked once. canHijack can be used to detect whether this request can be hijacked.


Never hijack(void Function(StreamChannel<List<int>>) callback) {
  if (_onHijack == null) {
    throw StateError("This request can't be hijacked.");


  throw const HijackException();
