30-second quickstart

import 'package:ctrlapp/ctrlapp.dart';

await CtrlApp.init(
  apiKey: 'ck_pub_...',
  baseUrl: 'https://ctrlapp.dev', // override for self-hosted
);

final c = CtrlApp.instance;

// 1. The kill-switch — works offline from local cache.
if (c.blocked()) return MaintenanceScreen(reason: c.blockReason());

// 2. Feature flag
if (c.flag('checkout_v2').isOn) return NewCheckout();

// 3. Remote copy / images / deep links
final label = c.text('cta_primary', 'Buy now');
final hero  = c.image('hero_banner');
final url   = c.link('promo_target');

// 4. Live updates + kill-switch changes
c.subscribe((map) => setState(() {}));
c.blockChanges.listen((b) => rerender());

More in this package

Everything is one package, ctrlapp. Next to the main CtrlApp object there are independent building blocks you can use on their own:

Need	Use
Crash and error reporting (opt-in, redacted)	CtrlAppDiagnostics, CtrlAppHandlers, CtrlAppDebugOverlay
Jailbreak / root / emulator / debugger signals	CtrlAppIntegrity.detect()
Device model and OS details	CtrlAppDeviceInfo.detect()
Notification permission and push tokens	CtrlAppPush.requestPermission()
Re-check the kill-switch while the app is open	CtrlAppBlockWatch
Low-level client, transport and mock transport for tests	CtrlAppClient, HttpCtrlAppTransport, MockCtrlAppTransport
Hosted social login and app session	package:ctrlapp/auth.dart

import 'package:ctrlapp/ctrlapp.dart';

final diagnostics = CtrlAppDiagnostics();
CtrlAppHandlers(diagnostics).install(); // chains FlutterError / platform handlers

final signals = await CtrlAppIntegrity.detect();
final status = await CtrlAppPush.requestPermission();

The login surface uses generic names (Loading, Offline, Expired, ...), so it lives in its own library: import 'package:ctrlapp/auth.dart';

Screen Capture Protection

The per-app Screen Capture Protection dashboard switch is enforced on Android in this release via WindowManager.LayoutParams.FLAG_SECURE on the attached Activity. The policy value is cached per-apiKey and applied on cold start (before any network) so a killed feature stays protected offline. iOS enforcement (masking on capture) is planned for a following release; today the iOS side returns a safe no-op.

Ownership rule (Android): the plugin never clears a FLAG_SECURE that the host app or another library already set — it only releases the flag it added itself. Idempotent across attach / reattach / configuration changes.

Caveats (Android): FLAG_SECURE also blocks Assistant screenshots, some casting flows, and some accessibility / remote-support tools that work via screen capture. Leave the setting off unless you need it.
