    <div class="demo-select-all-checkboxes" flex="100" ng-repeat="item in items">

angular.module('MyApp',['ngMaterial', 'ngMessages'])

.controller('AppCtrl', function($scope) {
  $scope.items = [

  $scope.selectedItems = angular.copy($scope.items);

  $scope.toggle = function (index) {

      $scope.selectedItems.splice(index, 1);
    }
    else {
      $scope.selectedItems.splice(index, 0, $scope.items[index]);
