AWTY Engine (Are We There Yet?) #

A simple, reliable, and decoupled step tracking engine for Flutter applications. AWTY provides pure step counting and goal notification services, allowing you to focus on building your game's UI and logic.

Features #

• Reliable Background Tracking: Uses an Android Foreground Service to ensure step counting continues even when the app is closed.
• Real Pedometer Integration: Connects to the device's native step sensor for accurate, real-time data.
• Simple API: A clean and focused API for starting, stopping, and updating step counts.
• Customizable Notifications: Set a custom monochrome icon for the persistent status bar notification.
• Test Mode: Includes a 30-second test mode for rapid development and testing of goal-arrival events.

Getting Started #

1. Add Dependency #

Add this to your package's pubspec.yaml file:

dependencies:
  awty_engine: ^0.2.0

2. Android Setup #

Add the necessary permissions to your android/app/src/main/AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE_HEALTH" />
    <uses-permission android:name="android.permission.ACTIVITY_RECOGNITION" />
    <application ...>
        ...
    </application>
</manifest>

3. Place Notification Icon #

Place your small, monochrome notification icon (e.g., barefoot.png) in the android/app/src/main/res/drawable directory.

Usage #

1. Initialize the Engine and Pedometer #

In your main walking page's initState, initialize the AwtyEngine to listen for goal events and start your pedometer stream.

import 'package:awty_engine/awty_engine.dart';
import 'package:pedometer/pedometer.dart';
import 'dart:async';

class WalkingPage extends StatefulWidget {
  // ...
}

class _WalkingPageState extends State<WalkingPage> {
  StreamSubscription<StepCount>? _stepCountSubscription;

  @override
  void initState() {
    super.initState();
    _initialize();
  }

  void _initialize() {
    // Listen for goal reached events from AWTY
    AwtyEngine.initialize();
    AwtyEngine.onGoalReached = () {
      print("Goal Reached! Navigating to the arrival page.");
      // Navigate to your clue or arrival page here
    };

    // Listen to the pedometer stream
    _stepCountSubscription = Pedometer.stepCountStream.listen(
      (StepCount event) {
        // Send live step counts to the AWTY service
        AwtyEngine.updateStepCount(event.steps);
      },
      onError: (error) {
        print("Pedometer Error: $error");
      },
      cancelOnError: true,
    );
  }

  @override
  void dispose() {
    _stepCountSubscription?.cancel();
    super.dispose();
  }
  
  // ... rest of your widget
}

2. Start a Walk #

When you are ready to start a walk, call AwtyEngine.startTracking.

void startNewWalk() {
  AwtyEngine.startTracking(
    steps: 1000, // The number of steps for this goal
    notificationText: "Walking to the Eiffel Tower...",
    notificationIconName: 'barefoot', // The name of your icon file (without extension)
    testMode: false, // Set to true for 30-second test
  );
}

3. Stop a Walk (Optional) #

You can manually stop tracking at any time. The service will also stop itself automatically when a goal is reached.

void stopTheWalk() {
  AwtyEngine.stopTracking();
}
