Identify biometric type from isAvailable() function

[juicyapphk]

Feature Request

Feature Description

From current plugin version (v3.0.0) on Android, the isAvailable() function will only return either "biometric" (for Anroid P+) or "finger" (for older version) value.

Instead of "biometric" , is there any way we can identify whether the available biometric method is "Face Recognization" or "Fingerprint"?

Alternatively, will you consider separating the functions like:

• From isAvailable() to: isFaceAuthAvailable() and isFingerprintAuthAvailable()
• From show() to: showFaceAuth() and showFingerprintAuth()

Thanks for your great work!

I think there is now way in the Biometric Prompt API to determine which type is available.

See #179 (comment)

@exxbrain Correct me if I'm wrong.

I'm not sure, but I'm assuming that if the platform is Android, 'biometric' will mean fingerprint (is there an android device with face recognition? I guess just iPhone has it)

I'm facing same issue with android 9 operating system(samsung s 9 model) which has both face id and touch id and device is prompting for face id but, when I use plugin version 1.7.0 works fine with touch id as authentication mode with plugin version 3.0.1 it is looking for face id.

Is there any thing need to be updated from my side to handle this or device functionality ?

FYI - I'm not seeing this on One plus devices with OS version 10.0 (oxygen) which has both touch and face id.
