$mdtoast position bottom of page on scroll

Question

$scope.addPlaylist = function(song) {
      $scope.playlist.push(song);
      var el = angular.element(document.body);
      $mdToast.show(
        $mdToast.simple()
          .textContent(song.title + ' added to playlist.')
          .position('bottom')
          .hideDelay(3000)
          .parent(el)
      );
    }

I am not experienced with CSS and position properties and have just started using angular material. I am trying to make use of the mdtoast service but cannot get it to position correctly at the bottom of the page.

Even after setting the element to document.body the position of the mdtoast hovers in the middle of the page when I scroll down, as shown in the attached capture. How can I make it pop out from the bottom of the page even after scrolling.

The relevant html code :

The $mdToast gets trigged when addPlaylist() is called from within the md-list-item element.

Answer 1

So... Angular Material has a couple of issues with $mdToast with positioning at the moment (see the Github issues). There is a workaround however: adding layout and flex directives to the parent elements should solve the issue.
