AngularJS $stateProvider URL results in blank page - angularjs

Question

I'm using angular-ui-router and set up a 2nd controller similar to my 1st one which was working, but the route in the 2nd controller is not properly routing the app. Can someone please tell me where I went wrong?
html for first controller (works properly):
<div style="height: 100%"> <!--took out: ng-if="map.center !== undefined"-->
<ui-gmap-google-map
center='map.center'
zoom='map.zoom'
draggable='map.draggable'
dragging='map.dragging'
refresh='map.refresh'
options='map.options'
events='map.events'
pan='map.pan'>
<ui-gmap-circle
center='map.circle.center'
radius='map.circle.radius'
fill='map.circle.fill'
stroke='map.circle.stroke'
clickable='map.circle.clickable'
draggable='map.circle.draggable'
editable='map.circle.editable'
visible='map.circle.visible'
events='map.circle.events'>
</ui-gmap-circle>
</ui-gmap-google-map>
<script src='//maps.googleapis.com/maps/api/js?key=AIzaSyD_g7xCYEi-U54SYfTXQ_lukRsChkWgjXQ'></script>
</div>
1st controller (works properly ):
(function (window, ng) {
ng.module('app', ['uiGmapgoogle-maps', 'ui.router'])
.config(function ($stateProvider) { //had: , $stateChangeError included in the function parameters, but that caused error
$stateProvider.state('searchRadius', {
url: '/:lat/:lon',
templateUrl: 'searchRadius.html', //changed from index to searchRadius.html
controller: 'MapsCtrl',
});
})
.controller('MapsCtrl', ['$scope', "uiGmapLogger", "uiGmapGoogleMapApi", "$interval", "$state", "$stateParams",
function ($scope, $log, GoogleMapApi, $interval, $state, $stateParams) {
$log.currentLevel = $log.LEVELS.debug;
var center = { latitude: parseFloat($stateParams.lat), longitude: parseFloat($stateParams.lon) };
alert(JSON.stringify(center));
Object.freeze(center); //caused TypeError: Cannot assign to read only property ('latitude') ...
console.log($stateParams);
$scope.map = {
center: center,
pan: false,
zoom: 16,
refresh: false,
events: {},
bounds: {}
};
$scope.map.circle = {
id: 1,
center: center,
radius: 500, //(current time - date lost)*km/hour
stroke: {
color: '#08B21F',
weight: 2,
opacity: 1
},
fill: {
color: '#08B21F',
opacity: 0.5
},
geodesic: false, // optional: defaults to false
draggable: false, // optional: defaults to false
clickable: true, // optional: defaults to true
editable: false, // optional: defaults to false
visible: true, // optional: defaults to true
events: {
dblclick: function () {
$log.debug("circle dblclick");
},
radius_changed: function (gObject) {
var radius = gObject.getRadius();
$log.debug("circle radius radius_changed " + radius);
}
}
}
//Increase Radius:
$interval(function(){
$scope.map.circle.radius += 30; //dynamic var
}, 1000); //end of interval function
} ]); //end of controller
})(window, angular);
2nd html (blank page):
<!--Add ability to input location as address-->
<div>
<ui-gmap-google-map
center='map.center'
zoom='map.zoom'
draggable='map.draggable'
dragging='map.dragging'
refresh='map.refresh'

clickable='map.circle.clickable'
draggable='map.circle.draggable'
editable='map.circle.editable'

events='map.circle.events'>
</ui-gmap-circle>
</ui-gmap-google-map>
<script async defer

</div>
2nd controller (results in blank page with no errors):
(function (window, ng) {
ng.module('app', ['uiGmapgoogle-maps', 'ui.router'])
.config(function ($stateProvider) { //had: , $stateChangeError included in the function parameters, but that caused error
$stateProvider.state('getLocation', {
url: '/getLocation',
templateUrl: 'getlocation.html', //changed from index to searchRadius.html
controller: 'GetlocationCtrl',
});
})
.controller('GetlocationCtrl', ['$scope', "uiGmapLogger", "uiGmapGoogleMapApi", "$state", "$stateParams",
function ($scope, $log, GoogleMapApi, $state, $stateParams) {
$log.currentLevel = $log.LEVELS.debug;
var center = { latitude: 49.22, longitude: -122.66 }; //default center
alert(JSON.stringify(center));
console.log($stateParams);
$scope.map = {

} ]); //end of controller
})(window, angular);

Answer 1

(i) You are using $routerProvider which is not necessarily required
(ii) Also when i check your code, you are loading the first module after loading the 2nd controller. Place your scripts like this in index.html ,
<script src="searchRadius.js"></script>
<script src="getLoc.js"></script>
