======== Exception caught by widgets library ======================================================= The following ProviderNotFoundException was thrown building EditorPage(dirty, state: _EditorPageState#86f14): Error: Could not find the correct Provider above this EditorPage 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 EditorPage 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( create: (_) => Example(), // Will throw a ProviderNotFoundError, because `context` is associated // to the widget that is the parent of `Provider` child: Text(context.watch().toString()), ); } “` consider using `builder` like so: “` Widget build(BuildContext context) { return Provider( 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().toString()); } ); } “` If none of these solutions work, consider asking for help on StackOverflow: https://stackoverflow.com/questions/tagged/flutter The relevant error-causing widget was: EditorPage EditorPage:file:///C:/Users/Eddy/StudioProjects/itwi/lib/pages/diary_page.dart:209:24 When the exception was thrown, this was the stack: #0 Provider._inheritedElementOf (package:provider/src/provider.dart:343:7) #1 Provider.of (package:provider/src/provider.dart:293:30) #2 _EditorPageState.build (package:itwi/pages/editor_page.dart:131:40) #3 StatefulElement.build (package:flutter/src/widgets/framework.dart:4992:27) … ====================================================================================================

Add code like the sample below before your highest level MaterialApp(...).
ChangeNotifierProvider(
