Simple animation stopped on hot reload/hot restart with rive: 0.14.0-dev.6

Description

Simple animation stopped on hot reload/hot restart with rive: 0.14.0-dev.6
Am I doing something wrong with the new way of writing code?

Steps To Reproduce

Run this code:

import 'package:flutter/material.dart';
import 'package:rive/rive.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await RiveNative.init();
  runApp(const MaterialApp(home: SimpleAssetAnimation()));
}

class SimpleAssetAnimation extends StatefulWidget {
  const SimpleAssetAnimation({Key? key}) : super(key: key);

  @override
  State<SimpleAssetAnimation> createState() => _SimpleAssetAnimationState();
}

class _SimpleAssetAnimationState extends State<SimpleAssetAnimation> {
  File? file;
  RiveWidgetController? controller;
  bool isInitialized = false;

  @override
  void initState() {
    super.initState();
    initRive();
  }

  void initRive() async {
    file = await File.asset(
      'assets/timer.riv',
      riveFactory: Factory.rive,
    );
    controller = RiveWidgetController(file!);
    setState(() => isInitialized = true);
  }

  @override
  void dispose() {
    controller?.dispose();
    file?.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Simple Animation'),
      ),
      body: Center(
        child: isInitialized && controller != null
            ? RiveWidget(
                controller: controller!,
                fit: Fit.cover,
              )
            : const CircularProgressIndicator(),
      ),
    );
  }
}

Once running, it will works but as soon as you hot reload or hot restart it stopped.

Expected behavior

With rive: ^0.13.7
And this code, it works perfectly :

import 'package:flutter/material.dart';
import 'package:rive/rive.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(const MaterialApp(home: SimpleAssetAnimation()));
}

class SimpleAssetAnimation extends StatelessWidget {
  const SimpleAssetAnimation({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Simple Animation'),
      ),
      body: const Center(
        child: RiveAnimation.asset(
          'assets/timer.riv',
          fit: BoxFit.cover,
        ),
      ),
    );
  }
}
