How to allow floating notification and lock screen notification programmatic in flutter

Question

To implement push notification, Firebase Cloud Messaging is used.The notification is received successfully in the device but it has to be a pop-up(Floating notification) and it should also be displayed in lock screen. Notification is composed using Admin SDK in node.js environment. Please help to show the notification as a floating and lock-screen notification.

plugin used in flutter is firebase_messaging.

Solution

I suspect that it is not possible. On some launchers that are enabled when in some it is disabled (for energy-saving purposes I guess) by default.

The user should enable it manually from app settings=>notification section manually.
