Implementing Vibration in a Flutter App

In app development, implementing vibration is a basic yet highly versatile feature that you’ll want to implement as one of the first tutorial-like stages. The method for implementing vibration in Flutter app development is kept simpler compared to methods using Java and other languages.

Add the following to pubspec.yaml.

dependencies:
    vibration: ^1.7.3

Add the following to AndroidManifest.xml.

<uses-permission android:name="android.permission.VIBRATE"/>

Edit the dart file as follows. With this

import 'package:vibration/vibration.dart';

..

Vibration.vibrate();

Example of vibrating only when vibration functionality is available

if (await Vibration.hasAmplitudeControl()) {
    Vibration.vibrate(amplitude: 128);
}

If you want to specify vibration patterns or duration

Vibration.vibrate(duration: 1000);

Vibration.vibrate(pattern: [500, 1000, 500, 2000]);
