# volume_watcher
* 支持iOS和Android实时返回系统音量值，最大音量，初始音量，支持集卷。
## 入门
```
dependencies:
volume_watcher: ^1.3.0
```
## 对外提供如下方法：
```
VolumeWatcher.platformVersion
VolumeWatcher.getMaxVolume
VolumeWatcher.getCurrentVolume
VolumeWatcher.setVolume(0.0)
VolumeWatcher.addListener((double volume) {});
VolumeWatcher.removeListener(listenerId);
//仅对IOS生效
VolumeWatcher.hideVolumeView = true;
```
## 对外提供监听：
```
VolumeWatcher(
onVolumeChangeListener: (double volume) {
///do sth.
},
)
```
或者
```
final listenerId = VolumeWatcher.addListener((double volume) {});
// You can also cancel the listener with
VolumeWatcher.removeListener(listenerId);
```
## 使用示例：
```
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter/services.dart';
import 'package:volume_watcher/volume_watcher.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State {
String _platformVersion = 'Unknown';
double currentVolume = 0;
double initVolume = 0;
double maxVolume = 0;
@override
void initState() {
super.initState();
initPlatformState();
}
// Platform messages are asynchronous, so we initialize in an async method.
Future initPlatformState() async {
String platformVersion;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
VolumeWatcher.hideVolumeView = true;
platformVersion = await VolumeWatcher.platformVersion;
} on PlatformException {
platformVersion = 'Failed to get platform version.';
}
double initVolume = 0;
double maxVolume = 0;
try {
initVolume = await VolumeWatcher.getCurrentVolume;
maxVolume = await VolumeWatcher.getMaxVolume;
} on PlatformException {
platformVersion = 'Failed to get volume.';
}
// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
if (!mounted) return;
setState(() {
_platformVersion = platformVersion;
this.initVolume = initVolume;
this.maxVolume = maxVolume;
});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin Example App'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
VolumeWatcher(
onVolumeChangeListener: (double volume) {
setState(() {
currentVolume = volume;
});
},
),
Text("System Version=$_platformVersion"),
Text("Maximum Volume=$maxVolume"),
Text("Initial Volume=$initVolume"),
Text("Current Volume=$currentVolume"),
ElevatedButton(
onPressed: () {
VolumeWatcher.setVolume(maxVolume * 0.5);
},
child: Text("Set the volume to: ${maxVolume * 0.5}"),
),
ElevatedButton(
onPressed: () {
VolumeWatcher.setVolume(maxVolume * 0.0);
},
child: Text("Set the volume to: ${maxVolume * 0.0}"),
)
],
),
),
),
);
}
}
