Creating Provider In Riverpod

[DevThurain]

I am learning riverpod framework and a little bit confuse about creating providers.
I have a singleton class which do heavy calculation (asynchronous functions) in init state. I want to bind this class with provider but I don't want to use future provider. I will mainly read values from those provider and I don't want to use await every time I want to read values from those singleton provider. Is there any cleaner approach?

I finally understand the usage of ref.watch(provider).requireValue. It will solve it.
