Legacy Flash-based version of the Scratch programming editor
Scratch Flash is the legacy version of the Scratch visual programming environment used to teach coding through creative projects and animations.

Although deprecated and replaced by Scratch 3.0, this version remains available for archival and historical purposes or for environments still supporting Flash.
