I want to add TouchID / FingerprintScanner support to an app that I'm developing with React-Native@0.54+ and all packages that I use I cannot link the dependencies to it via react-native link (or even without package-name...). I'm running it via 'create-react-native-app' and using Expo Client. Any thoughts / help? i think you shoud detach expo. working with Expo gives you lots of benefit... but deeper you want to achieve, Expo will make you struggle. I suggest you to deatch Expo and work with libraries like https://github.com/naoufal/react-native-touch-id or https://github.com/hieuvp/react-native-fingerprint-scanner

I am looking for some guidance when using flutter over a platform channel to integrate with android fingerprint authentication. I have the android part working and the flutter app with call the method, but I can not seem to get just a pop-up of fingerprint authentication like I do in swift, which works fine in the same flutter app, in order for it to pass results to the flutter app and let the flutter app continue on. If anyone has any examples or some guidance it would be greatly appreciated. Try the local_auth plugin -- it comes with usage instructions and an example app.
