Angular ui router parse query params into booleans

Question

Consider such scenario of a state with query parameters. I\'d like to have them declared as flags so I can fetch then in the controller and get true, fals

Eventually the following has worked for me:

    var stringToBoolean = function (s) {
        if (typeof s != 'string') {
            return undefined
        }

        if (/1|true|TRUE/.test(s)) {
            return true
        } else if (/0|false|FALSE/.test(s)) {
            return false
        } else {
            return undefined
        }
     };

     $stateProvider.state('foo.bar', {
                 url: '/foobar?{flag1}',
                 ...
                 onEnter: function ($stateParams) {
                        $stateParams.flag1 = stringToBoolean($stateParams.flag1);
                 }
      });

It doesn't feel super clean, I'd rather to have had this functionality integrated into ui-router but at least I was able in this way to solve this in the level of the states, without polluting my controllers with this logic.
