FAB button backdrop

Hi @ hirenkorat3 - am trying to implement this from a FAB button, however the eventHandler doesn’t seem to blur the content I’ve placed inside the

tags:
<!-- fab placed to the bottom & center -->
<ion-fab vertical="bottom" horizontal="center" slot="fixed">
    <ion-fab-button (click)="toggle!=toggle ">
      <ion-icon name="arrow-dropup"></ion-icon>
    </ion-fab-button>
      <ion-fab-list side="top">
      <ion-fab-button><ion-icon name="logo-vimeo"></ion-icon></ion-fab-button>
      <ion-fab-button><ion-icon name="logo-facebook"></ion-icon></ion-fab-button>
      <ion-fab-button><ion-icon name="logo-twitter"></ion-icon></ion-fab-button>
      <ion-fab-button><ion-icon name="restaurant"></ion-icon>
        <div class="list-label">Meals</div>
      </ion-fab-button>
    </ion-fab-list>
  </ion-fab>

<div [ngClass]="{ 'blur' : toggle }">
  <ion-content
    <ion-card class="welcome-card">
      <ion-img src="/assets/shapes.svg"></ion-img>
      <ion-card-header>
        <ion-card-subtitle>Get Started</ion-card-subtitle>
        <ion-card-title>Welcome to Ionic</ion-card-title>
      </ion-card-header>
      <ion-card-content>
