Flutter_Messaging Do Not Play Sound on a Real Android Phone

Question

Currently, I have implemented the Firebase Cloud Messaging on my application. The notification is function in foreground and background.

When I run the app on emulator, the sound is play with the default music. Once I run on a real Android device, there is the notification but without any notification sound. Can someone show me where is the problems?
