On Vibration.vibrate() it throws a message null check operator called on null value

Flutter Version 2.8.1 Dart Version 2.15.1

Can you, please, provide an example? And remember that the plugin only supports async calls.

I had the same issue on my web project using flutter null safety. This is the code used for solution: try { bool? hasVibration = await Vibration.hasVibrator(); if (hasVibration != null && hasVibration) { bool? hasCustomVibration = await Vibration.hasCustomVibrationsSupport(); if (hasCustomVibration != null && hasCustomVibration) { await Vibration.vibrate(duration: c.duration!); } else { await Vibration.vibrate(); } } }...

Should be solved in the latest version.
