The shared preferences plugin is not working on my Flutter App for IOS. Whenever I install the plugin in pubspec.yaml, and run flutter clean, flutter pub get and flutter build ios on cd ios directory I get this error.

im build an app and storing a bunch of data in the shared preferences.

Future<void> initializeExerciseData() async { SharedPreferences prefs = await SharedPreferences.getInstance(); if (!prefs.containsKey(‘exercises_initialized’)) { Map<String, bool> initialData = { ‘arithmetic_completed’: false, ‘arithmetic_addSubOne’: false, ‘arithmetic_addSubTwo’: false, ‘arithmetic_addSubThree’: false, }; // Set Data To Shared Prefs initialData.forEach((key, value) { prefs.setBool(key, value); }); // Set Exercise Inıt To Shared Prefs prefs.setBool(‘exercises_initialized’, true); } } Category Screen (Such as Arithmetic) Future<void> […]

I have a bunch of ids stored in shared preferences as recipeIds. I want to loop through all of those ids and get the strings associated with them in. During my forEach loop, it only adds one id and then quits unexpectedly. Is there another way to get strings from shared preferences?

Here is a code that creates 2 clickable containers.

This is my class it contains slider with volume + and – buttons
Once the slider is tapped using buttons that need to save in pref and when i come back to this screen it need to show the pref saved value.
