copyDirectory function

Future<Directory?> copyDirectory(String path, Directory target)

Copy the directory at path recursively into target.

Returns null if path does not lead to a Directory, else the newly created Directory gets returned.

Implementation

Future<Directory?> copyDirectory(String path, Directory target) async {
  // See [copyDirectorySync] for the synchronous version.
  // ignore: avoid_slow_async_io
  if (!await FileSystemEntity.isDirectory(path)) return null;
  final source = Directory(path).absolute;
  final actualTargetDir = target.directory(source.name).absolute;
  await source.copyRecursively(actualTargetDir);
  return actualTargetDir;
}
