TS

import { LottieView } from "nativescript-lottie";

public yourLoadedEvent(args) {
    this._myLottie = args.object as LottieView; /// this is the instance of the LottieAnimationView
    this._myLottie.loop = false; // to get the completionBlock to fire the animation can not be looping because then it will never "complete"
    this._myLottie.completionBlock = (bool) => {
        console.log('lottie animaton complete', bool);
    }
}

NativeScript Angular

XML

<StackLayout>
    <LottieView width="100" height="150" [src]="src" [loop]="loop" [autoPlay]="autoPlay" (loaded)="lottieViewLoaded($event)"></LottieView>
</StackLayout>

Component

import { Component } from '@angular/core';
import { registerElement } from '@nativescript/angular';
import { LottieView } from 'nativescript-lottie';

registerElement('LottieView', () => LottieView);

@Component({
  templateUrl: 'home.component.html',
  moduleId: module.id
})
export class HomeComponent {
  public loop: boolean = true;
  public src: string;
  public autoPlay: boolean = true;
  public animations: Array<string>;

  private _lottieView: LottieView;

  constructor() {
    this.animations = [
      'Mobilo/A.json',
      'Mobilo/D.json',
      'Mobilo/N.json',
      'Mobilo/S.json'
    ];
    this.src = this.animations[0];
  }

  lottieViewLoaded(event) {
    this._lottieView = <LottieView>event.object;
    this._myLottie.loop = false; // to get the completionBlock to fire the animation can not be looping because then it will never "complete"
    this._myLottie.completionBlock = bool => {
      console.log('lottie animaton complete', bool);
    };
  }

<script>
    export default {
