Advanced Haptics

A Flutter plugin for playing powerful, custom haptic feedback patterns. This package provides a unified API for Android and iOS, giving developers access to fine-grained vibration control and Apple Core Haptics .ahap files.

---

✨ Features

• ✅ Unified API: A single, easy-to-use Dart API for both platforms.
• 🎯 Custom Waveforms: Full control of vibration timing, intensity, and looping.
• 🍎 Core Haptics on iOS: Play custom .ahap files and control the player state.
• 🧠 Predefined Patterns: A suite of built-in methods like lightTap(), success(), error() and more.
• 🧩 Native Android Effects: Access system-level vibration effects like tick, heavyClick, etc.
• 🛡️ Capability Detection: Easily check if a device supports advanced haptics.
• 🪶 Graceful Fallbacks: Sensible defaults for unsupported hardware or platforms.

🖥 Platform Support

Feature	Android (8.0+ / API 26+)	iOS (13.0+ / iPhone 8+)
Waveform	✅ Native	✅ Emulated
.ahap Playback	🔁 Fallback	✅ Native
Player Controls	❌ N/A	✅ Native
Amplitude Control	✅ Native	✅ Native
Predefined Patterns	✅ Native + Custom	✅ Native

ℹ️ Note: iPads do not support Core Haptics. Always use hasCustomHapticsSupport() before playing advanced patterns to ensure a good user experience.

🚀 Getting Started

(This section remains the same as it covers initial setup for both platforms)

1. Install

Add advanced_haptics to your pubspec.yaml dependencies:

dependencies:
  advanced_haptics: ^0.0.7 # Use the latest version

Then, run flutter pub get in your terminal.

2. Android Setup

Add the VIBRATE permission to your android/app/src/main/AndroidManifest.xml:

<manifest ...>
    <!-- Add this line -->
    <uses-permission android:name="android.permission.VIBRATE"/>
    <application ...>
    </application>
</manifest>

3. iOS Setup

To play custom patterns on iOS, add your .ahap files to your project assets (e.g., under an assets/haptics/ folder) and declare the folder in your pubspec.yaml:

flutter:
  assets:
    - assets/haptics/

---

📦 Usage

Import the package in your Dart file:

import 'package:advanced_haptics/advanced_haptics.dart';

General & Cross-Platform Methods

These methods are designed to work on both Android and iOS, with graceful fallbacks where necessary.

✅ Capability Check

final bool hasSupport = await AdvancedHaptics.hasCustomHapticsSupport();
if (hasSupport) {
  // Safe to use advanced haptics
}

⚡ Predefined Patterns

Use these for quick, consistent feedback across your app.

await AdvancedHaptics.lightTap();
await AdvancedHaptics.mediumTap();
await AdvancedHaptics.heavyRumble();
await AdvancedHaptics.success();
await AdvancedHaptics.error();

🛑 Stop All Vibrations

Immediately cancels any ongoing haptic effect on either platform.

///atTime for iOS only
await AdvancedHaptics.stop(atTime: 0.0);

---

Platform-Specific Features

These methods expose powerful, native-only features. Check for platform or use hasCustomHapticsSupport() before calling.

🤖 Android Specific

Custom Waveform (Android Preferred)

Design unique patterns with precise control over timings (in milliseconds), amplitudes (0-255), and an optional repeat index. While this is emulated on iOS, it provides the most granular control on Android.

// Plays a pattern, with no repeat
await AdvancedHaptics.playWaveform(
  [0, 100, 100, 200],     // Timings: [delay, on, off, on]
  [0, 180, 0, 255],       // Amplitudes for each segment
  repeat: -1              // -1 means no repeat
);

Native Android Effects (API 29+)

Play Android's built-in system haptic effects using an enum. This has no effect on iOS.

await AdvancedHaptics.playPredefined(AndroidPredefinedHaptic.tick);

Available enums: click, doubleClick, tick, heavyClick, pop, thud, ringtone1.

---

🍎 iOS Specific

Play .ahap File

Trigger your custom-designed haptic experiences on supported iPhones. This is the highest-fidelity way to play haptics on iOS.

await AdvancedHaptics.playAhap('assets/haptics/success.ahap');

Haptic Player Controls

These methods control the state of the active CHHapticAdvancedPatternPlayer on iOS, which is typically started by playAhap or playWaveform. They have no effect on Android.

// Pause the currently playing haptic pattern
await AdvancedHaptics.pause(atTime: 0.0);

// Resume a paused pattern
await AdvancedHaptics.resume(atTime: 0.0);

// Jump to 0.5 seconds into the pattern
await AdvancedHaptics.seek(offset: 0.5);

// Cancel all scheduled events and stop immediately
await AdvancedHaptics.cancel();
