BaiomySecureStorage class

A singleton wrapper around FlutterSecureStorage that provides typed read / write / update / delete / clear operations with built-in error handling.

All data is encrypted at rest using the platform's secure keychain (Keychain on iOS, Keystore on Android, libsecret on Linux).

Supported types: String, bool, int, double, and any JSON-serialisable object via setObject / getObject.

Usage:

await BaiomySecureStorage.instance.setString('access_token', 'abc123');
final token = await BaiomySecureStorage.instance.getString('access_token');
