int getValue = await PreferenceHelper().getIntPrefValue(key: key);

For double SET and GET

await PreferenceHelper().setDoublePrefValue(key: key, value: value);

double getValue = await PreferenceHelper().getDoublePrefValue(key: key);

For remove single value and clear all from Shared Preference

await PreferenceHelper().removePrefValue(key: key);

Using the Encryption Extension

This extension provides tools to encrypt map data using RSA and AES encryption algorithms. Below is a quick guide on how to utilize this functionality in your project:

  1. Load the Public Key: Ensure you load the public key before using the encryption methods. Call EncryptionService.loadPublicKey() to load the key from preferences.
  2. Encrypt Data: Extend a Map object with the MapEncryption extension and call the encrypted() method to encrypt its contents. This method generates a random secret key and IV, encrypts the map data with AES, and then encrypts the secret key with RSA.
  3. Access Encrypted Data: The encrypted() method returns a map containing:
    • encryptedData: The AES-encrypted map data in base64 format.
    • encryptedKey: The RSA-encrypted secret key in base64 format.
    • iv: The IV used for AES encryption in base64 format.

Example usage:

await EncryptionService.loadPublicKey(); Map<String, dynamic> myMap = {'key': 'value'}; Map<String, dynamic> encryptedMap = myMap.encrypted(); print(encryptedMap);

By following these steps, you can securely encrypt your map data using the provided extension.
