userDataDirAndApply static method

Future<String?> userDataDirAndApply({ required MyUserDataDirStore store, String? initialDir, Future<bool> confirmWarnings(List<String> warnings)?, Future<void> onAfterApply(String normalizedPath)?, String confirmButtonText = '选择文件夹', })

系统选目录 → 可选 warnings 确认 → MyUserDataDirSession.apply。

Implementation

  if (picked == null || picked.isEmpty) return null;

  await MyUserDataDirValidator.ensureExistingWritable(picked);
  final normalized = MyUserDataDirValidator.normalizePath(picked);
  final warnings = MyUserDataDirValidator.warningsFor(normalized);
  if (warnings.isNotEmpty && confirmWarnings != null) {
