Util functions for SAF (Storage Access Framework). Note that this package doesn't provide any read / write functions (go to saf_stream for that).

Usage

class SafUtil {
  /// Shows a folder picker dialog and returns the selected folder URI.
  ///
  /// [initialUri] is the initial URI to show in the dialog.
  /// [writePermission] is true if the folder should have write permission.
  /// [persistablePermission] is true if the permission should be persistable.

  /// Lists the contents of the specified directory URI.
  ///
  /// [uri] is the URI of the directory.

  /// Gets a [SafDocumentFile] object from the specified URI.
  ///
  /// [uri] is the URI of the file or directory.
