📦 Installation #

dependencies:
  fasq: ^0.3.7
  fasq_security: ^0.1.4

🚀 Quick Start #

Initialize QueryClient with the security plugin:

import 'package:fasq/fasq.dart';
import 'package:fasq_security/fasq_security.dart';

void main() async {
  // Create client with security plugin
  final client = QueryClient(
    securityPlugin: DefaultSecurityPlugin(),
  );

  // Initialize (generates/retrieves keys)
  await client.securityPlugin.initialize();

  runApp(QueryClientProvider(
    client: client,
    child: MyApp(),
  ));
}

🔐 Secure Queries #

Mark specific queries as secure. Their data will be encrypted in memory/disk and cleared when the app goes to the background (configurable).

QueryBuilder<String>(
  queryKey: 'auth-token',
  queryFn: () => api.login(),
  options: QueryOptions(
    isSecure: true,                // Enable security
    maxAge: Duration(minutes: 15), // Enforce expiry
  ),
  builder: (context, state) {
    // state.data is available only when authenticated
    return Text('Token: ${state.data}');
  },
)
