[Flutter] MenuDrawer can't fetch the correct provider route

Error: Could not find the correct Provider above this MenuDrawer Widget

This happens because you used a BuildContext that does not include the provider of your choice. There are a few common scenarios:

• 
  You added a new provider in your main.dart and performed a hot-reload. To fix, perform a hot-restart.
  
  
• 
  The provider you are trying to read is in a different route.
  
  Providers are "scoped". So if you insert of provider inside a route, then other routes will not be able to access that provider.
  
  
• 
  You used a BuildContext that is an ancestor of the provider you are trying to read.
  
  Make sure that MenuDrawer is under your MultiProvider/Provider. This usually happens when you are creating a provider and trying to read it immediately.
  
  For example, instead of:
  
  Widget build(BuildContext context) {
  return Provider<Example>(
  create: (_) => Example(),
  // Will throw a ProviderNotFoundError, because `context` is associated
  // to the widget that is the parent of `Provider<Example>`
  child: Text(context.watch<Example>().toString()),
  );
  }
  
  
  consider using builder like so:
  
  Widget build(BuildContext context) {
  return Provider<Example>(
  create: (_) => Example(),
  // we use `builder` to obtain a new `BuildContext` that has access to the provider
  builder: (context, child) {
  // No longer throws
  return Text(context.watch<Example>().toString());
  }
  );
  }

I was expecting of opening a drawer with some buttons but it's giving this error, i tried gpt. it was working good but some error occurred in the same file, when i changed it, this error came in
