authenticate method

Future<bool> authenticate()

Requests biometric authentication using the Flutter Local Authentication plugin.

This method triggers a biometric authentication prompt, allowing the user to authenticate using their fingerprint, face, or other biometric methods supported by the device. If the user successfully authenticates, the method returns true. If authentication fails or is canceled, it throws an error.

Note: Biometric authentication must be supported on the device, and the user must have set up biometrics in their device settings for this method to work.

Returns true if authentication succeeds.

Throws an exception if there's an issue with the authentication process.
