2. Usage

Step 1: Define a SessionController

final SessionController sessionController = SessionController(
  timeoutInSeconds: 180, // e.g., 3 minutes
  onSessionExpired: () {
    // Handle session expiration, e.g., show alert or logout
  },
);

Step 2: Wrap your widget tree

MaterialApp(
  navigatorKey: appNavigatorKey,
  home: SessionWrapper(
    controller: sessionController,
    child: YourAppHome(),
  ),
);

Step 3: Start the session

sessionController.startSession();

🧪 Example

void main() {
  sessionController.startSession();

  runApp(
    MaterialApp(
      navigatorKey: appNavigatorKey,
      home: SessionWrapper(
        controller: sessionController,
        child: SessionWrapperExample(),
      ),
    ),
  );
}

Inside SessionWrapperExample, user taps reset the session timer. If inactive for the set timeout duration, the session expires.
