cleanup method

Implementation

Future<void> cleanup({Duration? olderThan}) async {
  final maxAge = olderThan ?? const Duration(days: 7);
  final cutoffTime = DateTime.now().subtract(maxAge);

  try {
    final tempDir = await getTemporaryDirectory();
    final walletTempDir =
        Directory(path.join(tempDir.path, _defaultDirectoryName));

    if (walletTempDir.existsSync()) {
      await for (final entity in walletTempDir.list()) {
        final stat = await entity.stat();
        if (stat.modified.isBefore(cutoffTime)) {
          await entity.delete(recursive: true);
        }
      }
    }
  } catch (e) {
    // Ignore cleanup errors
  }
}
