Android Integration (taken from local_auth) #
Note that local_auth plugin requires the use of a FragmentActivity as
opposed to Activity. This can be easily done by switching to use
FlutterFragmentActivity as opposed to FlutterActivity in your
manifest (or your own Activity class if you are extending the base class).
Update your project's AndroidManifest.xml file to include the
USE_FINGERPRINT permissions:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.app">
<uses-permission android:name="android.permission.USE_FINGERPRINT"/>
<manifest>
