The error message "Unable to display 'show' property of undefined using $mdToast" is displayed

I can't seem to figure out what's causing this issue...

Following the Angular material design guidelines, I expected this code to work. However, I keep getting an error that says:

TypeError: Cannot read property 'show' of undefined

Here is a snippet of my code:

<!DOCTYPE html>
<html lang="en" ng-app="Main">
<!-- some stuff here -->
    <link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/angular_material/1.1.0-rc4/angular-material.min.css">
</head>

<body ng-controller="MainCtrl as ctrl">
<div ng-click="executeToast()">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular-animate.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular-route.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular-aria.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular-messages.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular-sanitize.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angular_material/1.1.0-rc4/angular-material.min.js"></script>
</body>
</html>

And here is the controller code:

angular.module('MainController', [
        'MainService',
        'MainDirective',
        'ngMaterial', 
        'ngMessages',
        'ngSanitize'
    ])
    .controller('MainCtrl', [ '$scope', '$sce', '$mdToast', function($scope, Main, $sce, $apply, $rootScope, $mdToast) {
      $scope.executeToast() = function() {
           $mdToast.show($mdToast.simple({
              hideDelay: 3000,
              position: 'top left',
              content: 'testing',
              toastClass: 'success'
            }));
      }
}]);

If you have any insights or solutions, please let me know! Thanks!

Answer №1

Your code has a couple of mistakes that need to be corrected:

1. Make sure the sequence in dependency injection is consistent. More information can be found here.

2. There is no need to pass $apply as a dependency.

Consider using the following code:

.controller('MainCtrl', [ '$scope', '$rootScope', '$mdToast','$sce', function($scope, $rootScope, $mdToast, $sce) {
      $scope.executeToast() = function() {
           $mdToast.show($mdToast.simple({
              hideDelay: 3000,
              position: 'top left',
              content: 'testing',
              toastClass: 'success'
            }));
