Introduction:

The vibration package in Flutter allows you to trigger device vibrations on supported platforms. This can be useful for providing haptic feedback to users in your app. In this guide, you’ll learn how to integrate the vibration package into your Flutter app.

Content:

Step 1: Add Dependency

Ensure you have the vibration package added to your pubspec.yaml file. Run the following command in your terminal:

Copy Code


dependencies:
  flutter:
    sdk: flutter
  vibration: ^1.7.0  # Replace with the latest version

Run flutter pub get to fetch the package.

Step 2: Add permission in AndroidManifest.xml

Path:-android/app/main/AndroidManifest.xml

Copy Code


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

Step 3: Import Dependencie

In your Dart file, import the necessary package:

Copy Code


import 'package:flutter/material.dart';
import 'package:vibration/vibration.dart';

Step 4: Trigger Vibration

You can trigger vibrations using the Vibration.vibrate() method. For example:

Copy Code


Vibration.vibrate(duration: 1000); // Vibrate for 1 second

You can also specify a custom pattern of vibrations:

Copy Code


Vibration.vibrate(pattern: [500, 1000, 500, 2000]); // Vibrate with a custom pattern

Step 5: Check Vibration Support

Before triggering vibrations, it’s a good practice to check if the device supports vibration:

Copy Code


if (await Vibration.hasVibrator()) {
  Vibration.vibrate(); // Trigger vibration
} else {
  // Device does not support vibration
}

Step 5: Run the Application

Run your Flutter application on a supported device or emulator. When you trigger the vibration action, you should feel the device vibrating according to the specified duration or pattern.

Sample Code:

Copy Code

import 'package:flutter/material.dart';
import 'package:vibration/vibration.dart';

class VibratingApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        appBar: AppBar(
          backgroundColor: Colors.blue[200],
          centerTitle: true,
          title: Text(
            "Vibration Plugin",
            style: TextStyle(color: Colors.white),
          ),
        ),
        body: Builder(
          builder: (BuildContext context) {
            return Center(
              child: Column(
                children: <Widget>[
                  SizedBox(

                    child: Text(
                      'Vibrate for default 500ms',
                      style: TextStyle(fontSize: 18),
                    ),
                    onPressed: () {
                      Vibration.vibrate();
                    },
                  ),
                  SizedBox(

                      Vibration.vibrate(duration: 1000);

                    child: Text(
                      'Vibrate with pattern and amplitude',
                      style: TextStyle(fontSize: 18),
