In the Router class, call method is defined so that it can work like a handler

dart-neats/shelf_router/lib/src/router.dart

Lines 135 to 151 in 640b2d3

	/// Route incoming requests to registered handlers.
	///
	/// This method allows a Router instance to be a [Handler].
	Future<Response> call(Request request) async {
	// Note: this is a great place to optimize the implementation by building
	// a trie for faster matching... left as an exercise for the reader :)
	for (var route in _routes) {
	if (route.verb != request.method.toUpperCase() && route.verb != 'ALL') {

	if (params != null) {
	return await route.invoke(request, params);
