📦 Installation

dependencies:

Working Demo

🧑‍💻 Usage

1. Initialize the plugin (e.g. inside main())

void main() {
  runApp(MyApp());

  InAppIdleDetector.initialize(
    timeout: Duration(seconds: 10), // Set your own duration
    onIdle: () {
      // Called when user goes idle
      print("User is idle");
    },
    onActive: () {
      // Called when user becomes active again
      print("User is active");
    },
  );
}

2. Show a dialog or take action on idle

showDialog(
  context: navigatorKey.currentContext!,
  builder: (_) => AlertDialog(
    title: Text("Idle Warning"),
    content: Text("You've been inactive for 10 seconds."),
    actions: [
      TextButton(
        onPressed: () {
          Navigator.of(navigatorKey.currentContext!).pop();
        },
        child: Text("Dismiss"),
      ),
    ],
  ),
);

3. Extra API (Pause / Resume / Reset)

InAppIdleDetector.pause();  // Stop tracking temporarily
InAppIdleDetector.resume(); // Resume tracking
InAppIdleDetector.reset();  // Manually reset idle timer

4. Get Remaining Time

final timeLeft = InAppIdleDetector.remainingTime;
final idleStatus = InAppIdleDetector.isIdle;

✅ Use Cases

🔒 Auto-logout after inactivity (e.g., in banking apps)

🔐 Lock screen on desktops after idle

⏱️ Countdown timers for session expiration

📉 Inactivity analytics and user behavior tracking

Always use navigatorKey.currentContext for dialogs to ensure it works from anywhere. You can build a visual countdown using remainingTime and a Timer.periodic.
