Injecting data from component functions into Angular2 animations

Question

In angular 2 I am trying to use @angular/animations to make a component where a <li> element follows the mouse (ondrag) and stays in position after (ondragend). I am quite new to angular and very lost on what the best way to tackle this problem is. I would like to be able to inject a string from my component back into the animations but am not sure if this is possible. See an example below.

import { Component } from '@angular/core';

import { trigger, state, style, animate, transition } from '@angular/animations';

@Component({
  selector: 'test-test',
  template: `
  <li
  *ngFor="let letter of list"
  [@lettereState]="letter.state"
  (ondrag)="letter.toggleState(); mouseCords($event.clientX, $event.clientY);"
  (ondragend)="letter.toggleState()">
      {{letter}}
  </li> `,
  animations: [
    trigger('letterState', [
      state('active', style({
        transform: //'translate(Inject the cordinates here {mouseX}, {mouseY})',
      })),
    ])
  ],

})
export class LetterBankComponent {

  constructor(
  ) {}

  private list = ['a', 'b', 'c']
  private mouseX = ''
  private mouseY = ''
  }
  mouseCords(x, y) {
        mouseX = x;
        mouseY = y;
  }

In terms of injecting data into animations it is a feature request and coming soon maybe (see https://github.com/angular/angular/issues/9668). In terms of having a draggable element adding [draggable] to an element seems to solve this problem
