  flutter:
    sdk: flutter
  feature_spotlight: ^1.0.0  # Use the latest version from pub.dev

Install the package:

flutter pub get

📱 Basic Usage #

1. Wrap Your App #

Wrap your MaterialApp's child with the FeatureSpotlight widget:

import 'package:flutter/material.dart';
import 'package:feature_spotlight/feature_spotlight.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: FeatureSpotlight(
        child: MyHomePage(),
      ),
    );
  }
}

2. Create a Controller and Define Steps #

class _MyHomePageState extends State<MyHomePage> {
  late SpotlightController _controller;

  @override
  void initState() {
    super.initState();
    
    // Create a controller and define your steps
    _controller = SpotlightController(
      steps: [
        SpotlightStep(
          id: 'profile-icon',
          text: 'This is the default tooltip. Tap here to see your profile.',
          shape: SpotlightShape.circle,
        ),
        SpotlightStep(
          id: 'settings-button',
          text: 'Access your settings and preferences here.',
          shape: SpotlightShape.rectangle,
        ),
        SpotlightStep(
          id: 'add-button',
          text: 'Create new content with this button.',
          shape: SpotlightShape.circle,
        ),
      ],
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Feature Spotlight Demo'),
        actions: [
          // Wrap your target widgets
          SpotlightTarget(
            id: 'profile-icon',
            controller: _controller,
            child: IconButton(
              icon: const Icon(Icons.person),
              onPressed: () {},
            ),
          ),
          SpotlightTarget(
            id: 'settings-button',
            controller: _controller,
            child: IconButton(
              icon: const Icon(Icons.settings),
              onPressed: () {},
            ),
          ),
        ],
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            // Start the tour
            FeatureSpotlight.of(context).startTour(_controller);
          },
          child: const Text('Start Tour'),
        ),
      ),
      floatingActionButton: SpotlightTarget(
        id: 'add-button',
        controller: _controller,
        child: FloatingActionButton(
          onPressed: () {},
          child: const Icon(Icons.add),
        ),
      ),
    );
  }
}

🎨 Full Customization #

For complete control over the tooltip's appearance, use the tooltipBuilder property on a SpotlightStep. This function gives you onNext and onSkip callbacks to control the tour:

SpotlightStep(
  id: 'add-button',
  shape: SpotlightShape.circle,
  tooltipBuilder: (onNext, onSkip) {
    return Container(
      padding: const EdgeInsets.all(16),
      decoration: BoxDecoration(
        borderRadius: BorderRadius.circular(12),
        color: Colors.deepPurple,
        boxShadow: [
          BoxShadow(
            color: Colors.black26,
            blurRadius: 10,
            offset: const Offset(0, 4),
          ),
        ],
      ),
      child: Column(
        mainAxisSize: MainAxisSize.min,
        children: [
          const Text(
            'This is a custom tooltip!',
            style: TextStyle(
              color: Colors.white,
              fontSize: 18,
              fontWeight: FontWeight.bold,
            ),
          ),
          const SizedBox(height: 10),
          const Text(
            'You can put any widget you want in here. Add images, buttons, or complex layouts.',
            style: TextStyle(color: Colors.white70),
          ),
          const SizedBox(height: 20),
          Row(
            mainAxisAlignment: MainAxisAlignment.end,
            children: [
              TextButton(
                onPressed: onSkip,
                child: const Text(
                  'Exit',
                  style: TextStyle(color: Colors.white),
                ),
              ),
              const SizedBox(width: 8),
              ElevatedButton(
                onPressed: onNext,
                style: ElevatedButton.styleFrom(
                  backgroundColor: Colors.white,
                  foregroundColor: Colors.deepPurple,
                ),
                child: const Text('Got it!'),
              ),
            ],
          ),
        ],
      ),
    );
  },
),

📋 SpotlightStep Properties #

🔄 Showing the Tour Only Once #

The package does not manage when the tour should be shown. This logic belongs in your application's state. You can use a state management solution or a simple package like shared_preferences to store a flag.

Using SharedPreferences #

import 'package:shared_preferences/shared_preferences.dart';

class _MyHomePageState extends State<MyHomePage> {
  bool _showTour = false;

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

  Future<void> _checkTourStatus() async {
    final prefs = await SharedPreferences.getInstance();
    final hasSeenTour = prefs.getBool('has_seen_tour') ?? false;
    
    setState(() {
      _showTour = !hasSeenTour;
    });

    // Auto-start tour for new users
    if (_showTour) {
      WidgetsBinding.instance.addPostFrameCallback((_) {
        FeatureSpotlight.of(context).startTour(_controller);
      });
    }
  }

  Future<void> _markTourAsSeen() async {
    final prefs = await SharedPreferences.getInstance();
    await prefs.setBool('has_seen_tour', true);
    setState(() {
      _showTour = false;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      // ... your UI
      bottomNavigationBar: Padding(
        padding: const EdgeInsets.all(16.0),
        child: _showTour
            ? ElevatedButton(
                onPressed: () {
                  FeatureSpotlight.of(context).startTour(_controller);
                  _markTourAsSeen();
                },
                child: const Text('Start Tour'),
              )
            : ElevatedButton(
                onPressed: () {
                  // Allow users to replay the tour
                  FeatureSpotlight.of(context).startTour(_controller);
                },
                child: const Text('Replay Tour'),
              ),
      ),
    );
  }
}

🛠 Advanced Usage #

Custom Spotlight Shapes #

SpotlightStep(
  id: 'custom-widget',
  shape: SpotlightShape.rectangle,
  // Add custom padding around the spotlight
  padding: const EdgeInsets.all(8.0),
),

Programmatic Tour Control #

class TourManager {
  static void startFeatureTour(BuildContext context, SpotlightController controller) {
    FeatureSpotlight.of(context).startTour(controller);
  }

  static void skipTour(BuildContext context) {
    FeatureSpotlight.of(context).skipTour();
  }

  static void nextStep(BuildContext context) {
    FeatureSpotlight.of(context).nextStep();
  }
}

Tour Events & Callbacks #

_controller = SpotlightController(
  steps: [...],
  onTourStarted: () {
    print('Tour started!');
  },
  onTourCompleted: () {
    print('Tour completed!');
    _markTourAsSeen();
  },
  onTourSkipped: () {
    print('Tour was skipped');
    _markTourAsSeen();
  },
);

📝 Best Practices #

✅ Do's #

• Keep tooltips concise -- Users want to get through tours quickly
• Use consistent styling -- Match your app's design language
• Test on different screen sizes -- Ensure tooltips fit properly
• Provide skip options -- Always give users a way out
• Show tours contextually -- Display them when features are introduced

❌ Don'ts #

• Don't overwhelm users -- Limit tours to 3-5 steps maximum
• Don't show tours repeatedly -- Use persistent storage to track completion
• Don't block critical functionality -- Ensure users can still use the app
• Don't use tiny touch targets -- Make buttons easy to tap
