Optional query params aqueduct

Question

Went through the documentation, couldn't find any.

How does one make an optional query param in aqueduct?

Answer 1

By wrapping an argument in curly brackets:

@Operation.get()
Future<Response> getAllCities({@Bind.header('x-api-key') String apiKey}) async 
{}

This is documented here: http://aqueduct.io/docs/http/resource_controller/#optional-bindings
