// Create storage
final _storage = new StoreCriticalData();

// write String value
_storage.writeString(key: “key”, value: “value”);

// Read String value
String value = _storage.readString(key: "key");

// write Double value
_storage.writeDouble(key: “key”, value: “value”);

// Read Double value
final double value = _storage.readDoubleNew(key: "key");

// Clear value
_storage.clear(key: "key");
