    The error you’re encountering suggests that the Flutter plugin path_provider is missing or not correctly integrated into your project. This is likely causing issues when fetching the temporary directory for your audio asset.

    Make sure you’re calling WidgetsFlutterBinding.ensureInitialized() before any other plugin initializations.

    import 'package:flutter/material.dart';
import 'package:path_provider/path_provider.dart'; // is this imported correctly?

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(MyApp());
}
