FlutterKillSwitch class

A Flutter widget that provides an admin interface for controlling the kill switch functionality of your application.

This widget displays a toggle switch that allows administrators to enable or disable the kill switch state, which is synchronized with Firebase Firestore in real-time.

Features

• Real-time synchronization: Changes are instantly reflected across all app instances
• Confirmation dialog: Prevents accidental enabling with a confirmation step
• Dark theme design: Matches modern app aesthetics
• Responsive UI: Adapts to different screen sizes
• Error handling: Gracefully handles network and Firebase errors

Usage

Navigator.push(
  context,
  MaterialPageRoute(
    builder: (context) => const FlutterKillSwitch(),
  ),
);

Firebase Configuration

Ensure your Firebase project is configured with Firestore and the necessary security rules are in place. The widget uses a specific collection path for storing the kill switch state.

State Management

The widget maintains the following internal states:

• _killSwitchEnabled: Current state of the kill switch
• _isLoading: Whether the widget is loading the initial state
• _showingDialog: Whether the confirmation dialog is currently displayed

See also:

• KillSwitchWrapper, which wraps your app to show blocking dialogs
• KillSwitchDialog, the dialog shown to end users when kill switch is active
• FirebaseService, the service that handles Firestore operations
