First, you will need to add a git dependency on pub to your pubspec.yaml:

dev_dependencies:
  pub:
    git:
      url: https://github.com/dart-lang/pub/
      ref: master

	void main() {
	print(add << null << 1);
	print(add << 1 << null);
	print(add << 1 << 2);
	}

	int add(int a, int b) => a + b;

	extension IfNotNull<R, T extends Object> on R Function(T)? {
	R? operator <<(T? input) {

	export 'package:guinness/guinness.dart'
	- hide Expect, expect, NotExpect, beforeEach, it, iit, xit;
	+ hide
	+ Expect,
	+ expect,
	+ NotExpect,
	+ beforeEach,
	+ it,
	+ iit,
	+ xit,
