How to implement vibration with Flutter for both Android and iOS?

Question

Using Flutter I am trying to implement vibration on a button click.

I find it surprisingly difficult to be honest. I\'ve tried using the following packages unsuccessfully

Answer 1

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

// Note:
// Make sure you add the following permissions to your Android Manifest
// 
// 
// In pubspec.yaml file, add following dependency
// dependencies:
//   vibrate: ^0.0.4

class TestVibration extends StatefulWidget {
  @override
  _TestVibrationState createState() => _TestVibrationState();
}

class _TestVibrationState extends State {

  bool canVibrate = false;
  @override
  void initState() {
    super.initState();
    _checkIfVibrate();
  }
  _checkIfVibrate() async {
    // check if device can vibrate
    canVibrate = await Vibrate.canVibrate;
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      child: RaisedButton(
        child: Text('Vibrate'),
        onPressed: (){
          // FeedbackTypes -> {success, error, warning, selection, impact, heavy, medium, light}
          _getVibration(FeedbackType.warning);
        },
      ),
    );
  }

  _getVibration(feedbackType) async {
    if (canVibrate) {
      Vibrate.feedback(feedbackType);
      // Vibrate.vibrate();   // Try this too!
    }
  }
}
