How to Programmatically Vibrate Device with Dart in Flutter App
Introduction
Vibration is a crucial feature in mobile applications, as it provides a tactile way to alert users of important events or notifications. In Flutter, you can programmatically vibrate a device using the Haptic Feedback library. This library provides a simple and easy-to-use API for accessing the device’s vibrational capabilities.
Understanding Haptic Feedback
Haptic Feedback is a library that allows you to access the device’s vibrational capabilities. It provides a range of methods for creating different types of vibrations, from simple buzzes to complex patterns. To use Haptic Feedback in your Flutter app, you need to add the `haptic_feedback` package to your `pubspec.yaml` file.
Implementing Vibration in Flutter
To implement vibration in your Flutter app, you need to import the `haptic_feedback` package and use the `HapticFeedback` class. Here’s an example of how to use it:
“`dart
import ‘package:flutter/material.dart’;
import ‘package:hapticfeedback/hapticfeedback.dart’;
class VibrationExample extends StatefulWidget {
@override
VibrationExampleState createState() => VibrationExampleState();
}
class _VibrationExampleState extends State
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: ElevatedButton(
child: Text(‘Vibrate’),
onPressed: () {
HapticFeedback.vibrate();
},
),
),
);
}
}
“`
Customizing Vibration Patterns
The `HapticFeedback` class provides a range of methods for creating custom vibration patterns. For example, you can use the `HapticFeedback.mediumImpact()` method to create a medium-strength vibration, or the `HapticFeedback.lightImpact()` method to create a light vibration.
“`dart
HapticFeedback.mediumImpact(); // Medium-strength vibration
HapticFeedback.lightImpact(); // Light vibration
HapticFeedback.heavyImpact(); // Heavy vibration
HapticFeedback.selectionClick(); // Selection click vibration
“`
