🚀 Getting Started

1. Add Dependency

dependencies:
  flutter_activity_kit: ^0.1.0

---

2. Platform Setup

🍏 iOS Setup (Live Activities & Dynamic Island)

1. Set iOS Deployment Target to iOS 16.1 or higher in your Xcode project settings.
2. In ios/Runner/Info.plist, enable Live Activities:

   <key>NSSupportsLiveActivities</key>
   <true/>
   <key>NSSupportsLiveActivitiesFrequentUpdates</key>
   <true/>
   

3. Add a Widget Extension to your Xcode project:
   • In Xcode: File -> New -> Target... -> Widget Extension.
   • Name it LiveActivityWidget and check Include Live Activity.
4. Generate the Swift widget template using the CLI tool:

   dart run flutter_activity_kit:generate_swift --name DeliveryStatus
   

   Add the generated Swift file to your Widget Extension target in Xcode.

---

🤖 Android Setup (Ongoing Notifications)

1. Add the notification permission in android/app/src/main/AndroidManifest.xml:

   <uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>
   

2. Request notification permissions at runtime on Android 13+ (API 33+).

📖 Usage Guide

Starting a Live Activity

import 'package:flutter_activity_kit/flutter_activity_kit.dart';

// Start a food delivery live activity
final session = await FlutterActivityKit.startActivity(
  // Static attributes (immutable during the activity)
  attributes: const MapActivityAttributes({
    'orderId': 'ORD-9921',
    'restaurant': 'Bella Pizza',
  }, customActivityType: 'DeliveryAttributes'),

  // Initial dynamic state
  content: const ActivityContent(
    state: MapActivityContentState({
      'title': 'Order Placed',
      'message': 'Restaurant is preparing your pizza',
      'status': 'Preparing 🍕',
      'progress': 0.25,
    }),
    relevanceScore: 80.0,
    alert: ActivityAlert(
      title: 'Order Confirmed',
      body: 'Your pizza is on its way!',
    ),
  ),

  // iOS-specific configuration
  iosOptions: const IOSOptions(
    activityType: 'DeliveryAttributes',
    pushType: 'token',
  ),

  // Android-specific ongoing notification options
  androidOptions: const AndroidOptions(
    channelId: 'deliveries',
    channelName: 'Order Deliveries',
    category: 'progress',
    priority: 2,
    actions: [
      ActivityAction(id: 'call_courier', title: 'Call Courier'),
      ActivityAction(id: 'cancel', title: 'Cancel', isDestructive: true),
    ],
  ),
);

print('Activity started with ID: ${session.id}');

---

Updating Dynamic State

// Update using the active session instance
await session.update(
  const ActivityContent(
    state: MapActivityContentState({
      'title': 'Out for Delivery',
      'message': 'Courier is 3 minutes away',
      'status': 'On the Way 🛵',
      'progress': 0.85,
    }),
    alert: ActivityAlert(
      title: 'Almost There!',
      body: 'Courier is turning onto your street.',
    ),
  ),
);

---

Ending an Activity

// End immediately or with an automatic system dismissal delay
await session.end(
  finalContent: const ActivityContent(
    state: MapActivityContentState({
      'title': 'Delivered',
      'message': 'Enjoy your meal!',
      'status': 'Delivered 🎉',
      'progress': 1.0,
    }),
  ),
  dismissalPolicy: ActivityDismissalPolicy.immediate, // or .defaultPolicy / .after(dateTime)
);

---

Listening to Remote Push Tokens & Actions

// Listen to APNs push tokens for server-side push-to-update
session.pushTokenStream.listen((tokenHex) {
  print('Push Token for backend: $tokenHex');
  // Send token to your backend (Firebase / AWS SNS / custom APNs server)
});

// Listen to notification action button clicks
session.actionStream.listen((event) {
  if (event.actionId == 'call_courier') {
    // Open phone dialer
  } else if (event.actionId == 'cancel') {
    // Cancel the order
  }
});

---

🎨 In-App Flutter Previews

Test and visually verify your Dynamic Island and Ongoing Notifications directly in your Flutter widgets without needing a physical device with Dynamic Island!

// Expanded Dynamic Island
DynamicIslandPreview(
  style: DynamicIslandStyle.expanded,
  leading: const Icon(Icons.local_pizza, color: Colors.amber),
  trailing: const Text('12m', style: TextStyle(color: Colors.greenAccent)),
  center: const Text('Bella Pizza - Baking in Oven'),
  bottom: const LinearProgressIndicator(value: 0.5),
)

// Compact Pill
DynamicIslandPreview(
  style: DynamicIslandStyle.compact,
  leading: const Icon(Icons.local_pizza, size: 14, color: Colors.amber),
  trailing: const Text('12m', style: TextStyle(color: Colors.greenAccent, fontSize: 11)),
)

// Android Ongoing Notification Card
OngoingNotificationPreview(
  appName: 'Foodie Delivery',
  subText: 'Order #9921',
  title: 'Out for Delivery',
  body: 'Driver is 5 mins away',
  progress: 0.75,
  actions: [
    TextButton(onPressed: () {}, child: const Text('Call Driver')),
  ],
)
