simplePrompt method

Future<SimplePromptResult> simplePrompt(
  1. String promptMessage,
  2. SimplePromptConfig? config
)

Performs simple biometric authentication without cryptographic operations.

This is useful for:

  • Quick re-authentication flows
  • Confirming user presence before sensitive operations
  • Simple access control without key management

promptMessage is the main message shown to the user (title on Android). config contains optional platform-specific configuration.

Returns a SimplePromptResult indicating success or failure.

Implementation

Future<SimplePromptResult> simplePrompt(
    String promptMessage, SimplePromptConfig? config) async {
  final String pigeonVar_channelName =
      'dev.flutter.pigeon.biometric_signature.BiometricSignatureApi.simplePrompt$pigeonVar_messageChannelSuffix';
  final BasicMessageChannel<Object?> pigeonVar_channel =
      BasicMessageChannel<Object?>(
    pigeonVar_channelName,
    pigeonChannelCodec,
    binaryMessenger: pigeonVar_binaryMessenger,
  );
  final Future<Object?> pigeonVar_sendFuture =
      pigeonVar_channel.send(<Object?>[promptMessage, config]);
  final List<Object?>? pigeonVar_replyList =
      await pigeonVar_sendFuture as List<Object?>?;
  if (pigeonVar_replyList == null) {
    throw _createConnectionError(pigeonVar_channelName);
  } else if (pigeonVar_replyList.length > 1) {
    throw PlatformException(
      code: pigeonVar_replyList[0]! as String,
      message: pigeonVar_replyList[1] as String?,
      details: pigeonVar_replyList[2],
    );
  } else if (pigeonVar_replyList[0] == null) {
    throw PlatformException(
      code: 'null-error',
      message: 'Host platform returned null value for non-null return value.',
    );
  } else {
    return (pigeonVar_replyList[0] as SimplePromptResult?)!;
  }
}
