Introduction

The Vault facade provides a simple interface for securely storing sensitive data on the device. It uses the platform's native secure storage mechanisms:

• iOS: Keychain
• Android: EncryptedSharedPreferences
• macOS: Keychain
• Windows: Windows Credential Locker

Storing Items

To store a value in the vault:

await Vault.put('api_token', 'super-secret-token');

Retrieving Items

To retrieve a value:

final token = await Vault.get('api_token');

if (token != null) {
  // Use token...
}

Removing Items

To remove a specific item:

await Vault.delete('api_token');

To wipe all data from the vault (use with caution):

await Vault.flush();
