FCM flutter enable notification vibration - firebase

Question

I'm developing a Flutter application for Android and IOS. I have created notification channels for Android according to this article.
My node.js payload:
const payload = {
notification: {
title: "title",
},
android: {
priority: "high",
ttl: 60 * 60 * 1,
notification: {
channel_id: 'YO',
},
},
apns: {
payload: {
aps: {
sound: "sound_03.caf"
}
},
headers: {
"apns-collapse-id": "yo",
"apns-priority": "10"
}
},
priority: 10
}
My notifications are working just fine, for both Android and IOS using. The problem is that vibration is disabled by default.
How to enable notification vibration for Android and IOS for Firebase Cloud Messaging?

Answer 1

You can set the sound property to default so it makes uses the default sound if sound is enabled and it vibrates if the device is on vibrate.
You can update your payload to this:
const payload = {
notification: {
title: "title",
sound: "default"
},
android: {
priority: "high",
ttl: 60 * 60 * 1,
notification: {
channel_id: 'YO',
},
},
apns: {
payload: {
aps: {
sound: "default"
}
},
headers: {
"apns-collapse-id": "yo",
"apns-priority": "10"
}
},
priority: 10
}

For me, I only needed to add it to the notification portion of the message payload.
Below is how it looks in Typescript (but the message JSON is all that matters).
let tokens = ...
let message = {
message: {
notification: {
title: title,
body: body,
sound: 'default', // <----- All I needed
},
data: {
...
},
}
}
firebase.messaging().sendToDevice(tokens, message)
