Flutter Haptic Feedback On Long Press

Question

How are we supposed to cause haptic feedback on long press using Flutter HapticFeedback class?

I am currently working with HapticFeedback.selectionClick() during my OnTapDown method, but nothing is happening.

I have also already added the vibrate permission in the android manifest file. I am using a Pixel2 XL device for testing.

You can use vibrate plugin for that.
Add this dependency in your pubspec.yaml file

vibrate: ^0.0.4

Use this function in your class for vibration

void vibrate() async {
    bool canVibrate = await Vibrate.canVibrate;
    canVibrate ? Vibrate.feedback(FeedbackType.medium) : null;
  }

And call the above function from your widget when the onLongPress event is triggred

 onLongPress: () {
          vibrate();
        },

@Bisclavret Remove the `if` condition, it should work, think it was mistakenly pasted from my project. See the edit. – Niraj Niroula Jul 09 '19 at 15:46
