authenticate method

@override Future<bool> authenticate({ BiometricType biometricType = BiometricType.none, String reason = "Authenticate", String? title, String? confirmText, bool useCustomUI = false, bool useDialogUI = false, String? cancelText, })

Initiates biometric authentication using the device's biometric sensors.

This method triggers the biometric authentication flow, which can use fingerprint, face recognition, or other biometric methods available on the device.

Parameters:

• biometricType: Specifies the type of biometric authentication to use. Required on iOS, optional on Android (Android will automatically use available methods). Defaults to BiometricType.none.
• reason: The reason for requesting authentication, displayed to the user. Defaults to "Authenticate".
• title: The title of the authentication dialog. If null, a default title will be used.
• confirmText: The text for the confirmation button in the authentication dialog. If null, a default text will be used.
• useCustomUI: Whether to use a custom UI for authentication (true) or the system default UI (false). Defaults to false.
• useDialogUI: Whether to use the Dialog UI for authentication (true) or the new UI (false) in Android. Defaults to false.
• cancelText: The text for the cancel button in the authentication dialog. Only used on Android. If null, a default text ("Cancel") will be used.

Returns a Future<bool> that completes with:

• true: If authentication was successful
• false: If authentication failed or was canceled by the user

Implementation

@override
Future<bool> authenticate({
  BiometricType biometricType = BiometricType.none,
  String reason = "Authenticate",
  String? title,
  String? confirmText,
  bool useCustomUI = false,
  bool useDialogUI = false,
  String? cancelText,
}) async {
  final Map<String, dynamic> arguments = {
    'biometricType': biometricType.name,
    'reason': reason,
    'title': title,
    'confirmText': confirmText,
    'useCustomUI': useCustomUI,
    'useDialogUI': useDialogUI,
    'cancelText': cancelText,
  };

  final result = await methodChannel.invokeMethod<bool>(
    'authenticate',
    arguments,
  );
  return result ?? false;
}
