I have a trouble with starting an example in JSFiddle, it's simple code with AngularJS module, but I get a error with injecting module.
Javascript code:
angular
  .module('App', ['ngMaterial'])
  .controller('Ctrl', function($scope) {
    $scope.text = 'Hello';
  });
Html code:
<div ng-app="App" ng-controller="Ctrl">
  {{ text }}
</div>
Please, help me to fix it. Link to my JSFiddle
                        
You need to change you javascript Load Type configuration. For example:
No wrap - in <body>or<head>Updated JSFiddle
