@capacitor/haptics: Supported flag

[aeharding]

Feature Request

Plugin

@capacitor/haptics

Description

Apps may want to have an "Enable Haptic Feedback" toggle. However, such a toggle doesn't make sense on devices that don't support haptics (such as Apple A2HS or in the Safari app).

It would be nice if the Haptics plugin had a function to return a boolean if haptics are supported on the current device.

Platform(s)

All

Preferred Solution

Haptics.supported() or such

Alternatives

Can do some rudimentary detection, such as:

!isNative() && !("vibrate" in window.navigator)

but that doesn't cover unsupported on native and may break if a new haptic web API is released.

On iOS 13 Apple added supportsHaptics method, so we could expose that since Capacitor supports iOS 13+.
But note that devices without haptics can still vibrate, haptics is a step forward vibration added on iPhone 7, but older devices can still use vibrate() method if they have vibration hardware, just not the haptics related methods.

Also, I think Apple didn't implement window.navigator.vibrate, so your check will probably disable haptics on all iOS devices despite they might support it.
