How to do face id authentication for both android and iOS in flutter

Question

Hi I try to look for resource about authentication using face id in flutter that available for both android and iOS. I have try to search some resources, but most of them say that face id only available in iOS. are there any guides or resources that I can read to use face id auth for both android and iOS?

Answer 1

The FaceID, pattern unlock etc are done on the device. It can't be customised to suit our need eg I wanted to use face recognition on iOS to use in my Flutter app but it's not possible.

Secondly, to have face id on Android the device needs to provide this feature. Eg Pixel 4 can do it but it is not possible in most of the Android phones.

In case this question is connected to this : Even on iOS, the FaceID, TouchID tells you whether the user is authorised or not. However, we can't get the face/touch parameters so as to store it in our database.
