I have this error: angular.js:13424 TypeError: Cannot read property 'setCenter' of undefined
at $cordovaGeolocation.getCurrentPosition.then.Dialogs.alert.title (create-spot.controller.js:33)

And here is the code that i'm using:

`function CreateSpotController($scope, $cordovaGeolocation, Dialogs, $ionicPlatform) {
$scope.showMap = false;

$scope.getCurrentPosition = function (options) {

  $scope.mapCreated = function (map) {
    $scope.map = map;
  };

  options = options || {
    timeout: 10000,
    enableHighAccuracy: false
    //maximumAge: 5000
  };

  $ionicPlatform.ready(function () {

    $cordovaGeolocation
      .getCurrentPosition(options)
      .then(function (position) {
        //show map
        $scope.showMap = true;

        $scope.latitude = position.coords.latitude;
        $scope.longitud = position.coords.longitude;

        $scope.map.setCenter(new google.maps.LatLng(position.coords.latitude, position.coords.longitude));

      }, function(error) {
        // error
        Dialogs.alert({
          title: 'Error',
          message: error,
          buttonName: 'Aceptar'
        });
      });

  });

}; // end getCurrentPosition

} // end CreateSpotController`

can you help me please?
