getKeyInfo method

Future<KeyInfo> getKeyInfo(
  1. String? keyAlias,
  2. bool checkValidity,
  3. KeyFormat keyFormat
)

Gets detailed information about existing biometric keys.

keyAlias specifies which key to query. Defaults to the default alias. Returns key metadata including algorithm, size, validity, and public keys.
