E/flutter (24033): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Error: Could not find the correct Provider<ExpensiveOnboardingData> above this Router<Object> Widget
E/flutter (24033):
E/flutter (24033): This happens because you used a `BuildContext` that does not include the provider
E/flutter (24033): of your choice. There are a few common scenarios:
E/flutter (24033):
E/flutter (24033): - You added a new provider in your `main.dart` and performed a hot-reload.
E/flutter (24033):   To fix, perform a hot-restart.
E/flutter (24033):
E/flutter (24033): - The provider you are trying to read is in a different route.
E/flutter (24033):
E/flutter (24033):   Providers are "scoped". So if you insert of provider inside a route, then
E/flutter (24033):   other routes will not be able to access that provider.
E/flutter (24033):
E/flutter (24033): - You used a `BuildContext` that is an ancestor of the provider you are trying to read.
E/flutter (24033):
E/flutter (24033):   Make sure that Router<Object> is under your MultiProvider/Provider<ExpensiveOnboardingData>.
E/flutter (24033):   This usually happens when you are creating a provider and trying to read it immediately.
E/flutter (24033):
E/flutter (24033):   For example, instead of:
E/flutter (24033):
E/flutter (24033):   ```
E/flutter (24033):   Widget build(BuildContext context) {
E/flutter (24033):     return Provider<Example>(
E/flutter (24033):       create: (_) => Example(),
E/flutter (24033):       // Will throw a ProviderNotFoundError, because `context` is associated
E/flutter (24033):       // to the widget that is the parent of `Provider<Example>`
E/flutter (24033):       child: Text(context.watch<Example>().toString()),
E/flutter (24033):     );
E/flutter (24033):   }
E/flutter (24033):   ```
E/flutter (24033):
E/flutter (24033):   consider using `builder` like so:
E/flutter (24033):
E/flutter (24033):   ```
E/flutter (24033):   Widget build(BuildContext context) {
E/flutter (24033):     return Provider<Example>(
E/flutter (24033):       create: (_) => Example(),
E/flutter (24033):       // we use `builder` to obtain a new `BuildContext` that has access to the provider
E/flutter (24033):       builder: (context, child) {
E/flutter (24033):         // No longer throws
E/flutter (24033):         return Text(context.watch<Example>().toString());
E/flutter (24033):       }
E/flutter (24033):     );
E/flutter (24033):   }
E/flutter (24033):   ```
E/flutter (24033):
E/flutter (24033): If none of these solutions work, consider asking for help on StackOverflow:
