authenticate method

  1. @override
Future<bool> authenticate()
override

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 returns false.

Note: Biometric authentication must be available 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, false otherwise.

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

Implementation

@override
Future<bool> authenticate() async {
  return await methodChannel.invokeMethod<bool>('authenticate') ?? false;
}
