Authentication based on callback without dialog #81

Closed ruisilva450 closed 6 years ago

Hi, I want to be able to get the fingerprint authentication active without the dialog.

I have a case where I need to have a screen that provides authentication via PIN AND fingerprint. On this screen I need to be able to keep the fingerprint sensor ready in case the user uses it without the need for a dialog to appear (this causes the need for user to tap a button of some kind on the previous PIN screen, which I don't want to have).

Steps to reproduce

  1. Have a screen with PIN and fingerprint input

  2. Start the sensor without the dialog

Expected behavior

The dialog doesn't exists and the sensor is ready to give a callback when the user uses it.

Actual behavior

The dialog appears.

Crashlog

None

Configuration

**Version of the Plugin: 1.4.5

Platform: e.g. iOS10+ / Android 6.0+ / UWP

Device: N/A

Thank you. I didn't saw that and maybe it's because I was testing on UWP expecting the same behavior...

Unfortunately, this feature can be only used on Android :/
