如何使用firebase通知为flutter应用程序启用通知声音？

Question

我正在构建一个带有 firebase 通知的 flutter 应用程序。但是，我需要自定义声音来进行通知。我已经在AndroidNotificationDetails下实现了

playSound: true, sound: RawResourceAndroidNotificationSound('notification'),

并将mp3文件复制到正确位置的raw文件夹中，但没有用。有没有人有办法解决这个问题？

Answer 1

将此声音键添加到您的通知负载中

{
    "to" : "AsS23rH5543:CI2k_AsS23rH5543CIZvvDMAsS23rH5543P1...",

    "notification" : {
      "body" : "your body",
      "title" : "Your Title",
      "icon" : "your icon",
      "sound" : "default"
    }
  }

Flutter 中的自定义通知

安卓设置

首先创建一个额外的通知通道

  // channel for default notifications
  const AndroidNotificationChannel channel = AndroidNotificationChannel(
      'wave_remote_notifications', // id
      'Wave messages and updates', // title
      description: 'Primary channel for notifications and messages in wave app',
      importance: Importance.max,
    );
   
   // channel for custom sound  
   const AndroidNotificationChannel channelAudio = AndroidNotificationChannel(
      'wave_remote_notifications_priority', // id
      'Wave messages and updates on priority', // title
      description: 'Primary channel for notifications and messages in wave app',
      sound: RawResourceAndroidNotificationSound('mario'),
      importance: Importance.max,
    );
    
    
    // if you use flutter_local_notification 
    
      await flutterLocalNotificationsPlugin
        .resolvePlatformSpecificImplementation<
            AndroidFlutterLocalNotificationsPlugin>()
        ?.createNotificationChannel(channel);
        
    await flutterLocalNotificationsPlugin
        .resolvePlatformSpecificImplementation<
            AndroidFlutterLocalNotificationsPlugin>()
        ?.createNotificationChannel(channelAudio);

你可以看到我们已经添加了

RawResourceAndroidNotificationSound('mario')

现在将 mp3/wav 文件添加到res/raw/yourmp3files.mp3

现在通知将起作用，但仅适用于调试模式，因为您添加的此文件不会包含在发布模式中

因此，之后您需要在

res/raw/keep.xml

中添加keep.xml，以将您的mp3files.mp3包含到构建中

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools"
    tools:keep="@raw/yourmp3files"
    />

iOS 设置

您必须将声音添加到 XCode 中。您只需将音频文件（.caf 或 .wav 支持的格式）拖放到 XCode 中的根目录（通常称为 Runner for Flutter）

仅此而已

FCM 有效负载

最后一步

{
    "to": "f31vmSf8Qy2N57_33C9cf3:APA91bHBaz7yyRrKQTr_25mLNK2OVlBjdMqM8ux8kQwaeQcsXE6XnOhio7Tp5-CABTFTSbV1vBqqfIVj9Qd9eUdqNi9oojq8FdOWI-l1CU9Xw16-Xb4ZHVTycOM7nIRudIAmMkU6fjbm",
    // "collapse_key": "type_a",
    "priority": "high",
    "notification": {
        "title": "New visitor request",
        "body": "Answer to accept",
        "sound": "mario.wav",
        "android_channel_id": "wave_remote_notifications_priority"
    },
    "data": {
        "title": "New visitor request",
        "body": "Answer to accept ",
        "sound": "mario",
    },
    "content_available": true,
    "apns": {
        "payload": {
            "aps": {
                "mutable-content": 1,
                "content-available": 1
            }
        }
    }
}

现在一切就绪，应该可以工作了
