 One use of this would be having the opportunity to **activate and deactivate** the service when we want, we can see this in the example that we have in this package, in which you can see that on each screen, we have a button that dynamically activates and deactivates the service. To do this is pretty simple:
 
 ```dart
-final bool _isActivatedSpellChecker = false;
-if (!_isActivatedSpellChecker) {
-    FlutterQuillExtensions.useSpellCheckerService(Localizations.localeOf(context).languageCode);
-} else {
-    // close the internal streams without completely closing the service
-    SpellCheckerServiceProvider.dispose(onlyPartial: true);
-    // since onlyPartial is true then we must manually disable the service for it to take effect in the UI
-    SpellCheckerServiceProvider.turnOffService();
-}
-_isActivatedSpellChecker = !_isActivatedSpellChecker;
+ SpellCheckerServiceProvider.toggleState();
+ // use isServiceActive to get the state of the service
+ SpellCheckerServiceProvider.isServiceActive();
+ setState(() {});
 ```
