renameSync method Null safety

FileSystemEntity renameSync(
  1. String newPath
)

Synchronously renames this file system entity.

Returns a FileSystemEntity instance for the renamed entity.

If newPath identifies an existing entity of the same type, that entity is removed first. If newPath identifies an existing entity of a different type, the operation fails and an exception is thrown.

Implementation

FileSystemEntity renameSync(String newPath);
