stop() / isSupported()

stop()

Stop any ongoing haptic playback.

Signature

stop(): void

Platform behaviour

Platform	Behaviour
iOS	Stops the CHHapticEngine pattern player
Android	No-op — Android's Vibrator.cancel() is unreliable for compositions

Usage

import HapticFeedback from "react-native-haptic-feedback";

// Start a long pattern
HapticFeedback.triggerPattern(pattern("oO=oO=oO"));

// Stop early (iOS only)
HapticFeedback.stop();

---

isSupported()

Synchronously check whether the device supports haptic feedback.

Signature

isSupported(): boolean

Returns

Platform	Returns true when…
iOS	Device supports Core Haptics (iPhone 8 / iOS 13+)
Android	Vibrator.hasVibrator() — device has any vibration hardware

Usage

import HapticFeedback from "react-native-haptic-feedback";

if (HapticFeedback.isSupported()) {
  HapticFeedback.trigger("impactMedium");
}

Notes

• This is a synchronous call — suitable for use in render functions and event handlers.
• The result is constant for the lifetime of the app; you do not need to re-check it.
