How to Programmatically Vibrate Device with Dart in Flutter App

In this example, we are going to show you the easiest way to implement vibration programmatically with Dart in Flutter App. You can control duration and pattern of vibration.

First, you need to add vibration Flutter package in your project depedency by adding following lines in pubspec.yaml file.

dependencies:
  flutter:
    sdk: flutter
  vibration: ^1.7.3

Import Package to Script:

import 'package:vibration/vibration.dart';

Add Vibration permission in android/app/src/main/AndroidManifest.xml

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

if (await Vibration.hasVibrator()) { //check if device has vibration feature
    Vibration.vibrate(); //500 millisecond vibration
}

Vibration.vibrate(duration: 1000); //1 Sec = 1000 millisecond

Vibration.vibrate(
  pattern: [
      500, //wait 0.5 second
      1000, //vibrate 1 second
      500, //wait 0.5 second
      3000 //vibrate 3 second.
      //add mroe pattern here
    ]
); //1 Sec = 1000 millisecond

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

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Home(),
    );
  }
}

class Home extends StatelessWidget{
  @override
  Widget build(BuildContext context) {
     return Scaffold(
        appBar: AppBar(
           title: Text("Device Vibration with Flutter"),
           backgroundColor: Colors.redAccent,
        ),
        body: Container(
          padding: EdgeInsets.all(20),
           child: Column(
             crossAxisAlignment: CrossAxisAlignment.center,
             children: [

               Container(
                  alignment: Alignment.center,
                  padding: EdgeInsets.all(5),
                  child: ElevatedButton(
                     child: Text("Vibrate Default"),
                     onPressed: () async {
                       if (await Vibration.hasVibrator()) { //check if device has vibration feature
                             Vibration.vibrate(); //500 millisecond vibration
                       }
                     },
                  ),
                ),
                
                Container(
                  alignment: Alignment.center,
                  padding: EdgeInsets.all(5),
                  child: ElevatedButton(
                     child: Text("Vibrate For 1 Sec"),
                     onPressed: (){
                       Vibration.vibrate(duration: 1000); //1 Sec = 1000 millisecond
                     },
                  ),
                ),

                Container(
                  alignment: Alignment.center,
                  padding: EdgeInsets.all(5),
                  child: ElevatedButton(
                     child: Text("Vibrate With Pattern"),
                     onPressed: (){
                       Vibration.vibrate(
                         pattern: [
                              500, //wait 0.5 second
                              1000, //vibrate 1 second
                              500, //wait 0.5 second
                              3000 //vibrate 3 second.
                              //add mroe pattern here
                            ]
                       ); //1 Sec = 1000 millisecond
                     },
                  ),
                )

           ],)
        ),
     );
