IPersistStore class abstract

PersistStore Interface to implementation.

You don't have to use try-catch, as it is done by the library.

Examples

SharedPreferences:

class SharedPreferencesImp implements IPersistStore {
 late SharedPreferences _sharedPreferences;

 @override
 Future<void> init() async {
   //Initialize the plugging
   _sharedPreferences = await SharedPreferences.getInstance();
 }

 @override
 Object? read(String key) {
     return _sharedPreferences.getString(key);
 }

 @override
 Future<void> write<T>(String key, T value) async {
     await _sharedPreferences.setString(key, value as String);
 }

 @override
 Future<void> delete(String key) async {
   await _sharedPreferences.remove(key);
 }

 @override
 Future<void> deleteAll() async {
   await _sharedPreferences.clear();
 }
}

Hive:

class HiveImp implements IPersistStore {
 late Box box;

 @override
 Future<void> init() async {
   await Hive.initFlutter();
   box = await Hive.openBox('myBox');
 }

 @override
 Object? read(String key) {
     return box.get(key);
 }

 @override
 Future<void> write<T>(String key, T value) async {
     await box.put(key, value);
 }

 @override
 Future<void> delete(String key) async {
   await box.delete(key);
 }

 @override
 Future<void> deleteAll() async {
   await box.clear();
 }
}
