I am using a Nima Aimation in one of my Dart files. However, I am unable to dispose it once it is completed. NimaAnimation has an abstract class for NimaController but unfortunately it does not have any dispose function to stop it.

The problem that I am facing because of this are the performance issues. I even tried using the performance overlay to observe the memory usage and I did notice that the animation is not disposed off and it continues rendering in the backend even when I have navigated to a new Screen. The code that I have written for this is:

import 'package:flutter/material.dart';

import 'dart:async';

import 'package:maui/screens/tab_home.dart';

import 'package:nima/nima_actor.dart';



class WelcomeScreen extends StatefulWidget {

  @override

  State createState() => new WelcomeScreenState();

}



class WelcomeScreenState extends State<WelcomeScreen> {

  bool delayed;

  var animatecontrol = null;

  NimaController nimaController;

 NimaActor nima ;

  void initState() {

    super.initState();

       nima = new NimaActor(

      "assets/quack",

      alignment: Alignment.center,

      fit: BoxFit.scaleDown,

      animation: 'welcome with hello',

      mixSeconds: 0.2,



    );

    new Future.delayed(const Duration(milliseconds: 6200), () {

      Navigator.of(context).pushReplacementNamed('/tab');

      setState(() {

     nima.controller;

        delayed = true;

      });

    });

  }



  void dispose() {

    super.dispose();



  }



  @override

  Widget build(BuildContext context) {

    MediaQueryData media = MediaQuery.of(context);



    var size = media.size;





    // TODO: implement build

    return (delayed == true)

        ? new TabHome()

        : new Scaffold(

            body: new Container(

                decoration: new BoxDecoration(

                  color: Colors.purple,

                ),

                child: new Stack(

                    alignment: AlignmentDirectional.bottomCenter,

                    children: <Widget>[

                      new Column(

                          mainAxisAlignment: MainAxisAlignment.center,

                          crossAxisAlignment: CrossAxisAlignment.center,

                          children: <Widget>[

                            new AspectRatio(

                              aspectRatio: size.height > size.width ? 1.5 : 3.8,

                              child: nima,

                            ),

                          ])

                    ])));

  }

}

Nima Animator has attributes paused and completed. These can help in controlling the animation state. for details refer to this link(example):
