Custom Animation Component Ionic 2 RC0 and Angular 2 -

since moving ionic 2 rc0, i'm trying create custom component animate list of objects in ngfor loop.

here code component.

import { component, trigger, keyframes, animate, transition, style, ngzone } '@angular/core';  @component({   selector: 'animation-target',   templateurl: 'animation-target.html',   animations: [       trigger('zoomin', [           transition('inactive => active', animate(1000, keyframes([               style({                   transform: 'opacity(0)  scale3d(.3, .3, .3);', offset: 0 }),               style({ transform: 'opacity(1)', offset: .50 }),           ]))),       ])   ] }) export class animationtarget {     title = 'app works!';     public zoomstate: string;      constructor(public zone: ngzone) {     }     triggeranimation() {         this.zoomstate = "active";     }      reset() {         this.zone.run(() => {             this.zoomstate = "inactive";         });     }  } 

here component html:

<animation-target [@zoomin]="zoomstate" (@zoomin.done)="reset()"></animation-target> 

here i'm attempting use component:

<ion-item *ngfor="let event of gameevents" text-wrap>   <h2 *ngif="event.category" animation-target [ngclass]="{'header-main': event.challenger, 'header-primary': !event.challenger }">{{event.category}} - {{event.time}} minutes: {{event.instigator}} {{event.description}}</h2> </ion-item> 

here css zoomin animation being stored in app.scss:

@keyframes zoomin {   {     opacity: 0;     transform: scale3d(.3, .3, .3);   }    50% {     opacity: 1;   } }  .zoomin {   animation-name: zoomin; } 

currently when go build app following output , error , i'm unsure i'm missing.
