Allow resource controller endpoints to take query params as optional arguments

[itsjoeconway]

An endpoint could have optional arguments to automatically grab query parameters. These shouldn't impact routing or which handler gets the query parameters. A signature for a handler could then look like this:

@httpget
Future getThings({String location, String name}) {}

where name and location are names of query parameters (case insensitive) and if they exist, those arguments are populated.

Good!

Now, how does one construct the URL?
example.com/search?limit=5&page=10 how would that be constructed to be optional?

The routing doc here, https://aqueduct.io/docs/http/routing/ doesn't mention anything about query params routes construction

By wrapping an argument in curly brackets:

@Operation.get()
Future<Response> foo({@Bind.query('name') String name}) async 
{}

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

@EddieKamau , when I use

@Operation.get()
Future<Response> foo({@Bind.query('q') String name}) async {}

and don´t send any query parameters, I receive the

The method '[]' was called on null.
Tried calling: []("q") #0 Object.noSuchMethod (dart:core-patch/object_patch.dart:53:5)

Can you help me please?
