This plugin stores Shared Preferences as encrypted values on device storage.

Encrypted Shared Preferences

This plugin stores Shared Preferences as encrypted values. It is decrypted when retrieved. You could use this side by side with regular Shared Preferences. Make sure to target iOS 9.0 and later if you're going to deploy for iOS.

Usage

Instantiate class:

EncryptedSharedPreferences encryptedSharedPreferences = EncryptedSharedPreferences();

Save value:

encryptedSharedPreferences.setString('sample', 'Hello, World!').then((bool success) {
    if (success) {
        print('success');
    } else {
        print('fail');
    }
});

Retrieve value:

encryptedSharedPreferences.getString('sample').then((String value) {
    print(value); /// Prints Hello, World!
});

Clear values:

/// Clears all values, including those you saved using regular Shared Preferences.
encryptedSharedPreferences.clear().then((bool success) {
    if (success) {
        print('success');
    } else {
        print('fail');
    }
});
