How to read data from external fingerprint scanner in Flutter

Question

I want to save multiple user fingerprints in Firebase database. So, If a user logins in my android app, he'll scan the finger from the external fingerprint scanner connected to my android device. After scanning I should get some kind of data back, I'll check if that data exists in my firebase, I'll login the user.

So that's it.

Can anyone help me with that?

I'm using the external fingerprint named: DigitalPersona U.are.U 4500 scanner

I think Native android has API's for reading the data from external fingerprint. But, I want to implement the same in flutter.
