我正在寻找一种在抖动应用程序中更改设备声音模式的方法。
因此,如果用户将设备设置为静音模式,则该应用将有权更改它。
我该如何应对?
有没有可以使用的插件?
我知道在React Native中有一个插件:react-native-ringer-mode
那个剂量正好是,我该如何在Flutter中做到这一点?
最佳答案
请使用此软件包https://pub.dev/packages/volume
和包装https://pub.dev/packages/vibration的振动

import 'package:flutter/material.dart';
import 'dart:async';
import 'package:volume/volume.dart';
void main() => runApp(MyApp());

@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
AudioManager audioManager;
int maxVol, currentVol;
@override
void initState() {
super.initState();
audioManager = AudioManager.STREAM_SYSTEM;
initPlatformState();
updateVolumes();
}
Future<void> initPlatformState() async {
await Volume.controlVolume(AudioManager.STREAM_SYSTEM);
}
updateVolumes() async {
// get Max Volume
maxVol = await Volume.getMaxVol;
// get Current Volume
currentVol = await Volume.getVol;
setState(() {});
}
setVol(int i) async {
await Volume.setVol(i);
}
@override
Widget build(BuildContext context) {
return MaterialApp(
