I tired Flutter Awsome Package for push notification but the problem is I was not able to schedule notification correctly when the price is same as current live rate in the backgorund.

I think your question is not about Flutter, actually. You need to transfer this responsibility to your backend. You only need to provide to your database with the Token of the user's device, and the Price and asset he wants to get notification for. The backend will handle the asset follow-up and, when the price reaches the user preference, you'll use the provided Token to send him a Push Notification.

This way, it will work even though the app is not running in the background
