使用 flutter 不停地振动

Question

我想写一个点击时的功能我想让phone不停地振动。

onPressed: () 
{
  Vibration.vibrate(duration: 100000,  );
},

我该怎么做？

你可以这样做

import 'dart:async';

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    bool _cancel = false;
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        appBar: AppBar(
          title: const Text("Vibration Demo"),
        ),
        body: Center(
          child: Column(
            mainAxisSize: MainAxisSize.min,
            children: [
              RaisedButton(
                onPressed: () {
                  Timer.periodic(
                    const Duration(seconds: 1),
                    (Timer timer) {
                      if (_cancel) {
                        timer.cancel();
                        _cancel = false;
                        return false;
                      }
                      return Vibration.vibrate(duration: 1000);
                    },
                  );
                },
                child: const Text("Start Vibrations"),
              ),
              RaisedButton(
                onPressed: () {
                  _cancel = true;
                },
                child: const Text("Stop Vibrations"),
              )
            ],
          ),
        ),
      ),
    );
  }
}
