A developer is creating a new version of Flash, a 2D animation authoring tool, from scratch in C# with Avalonia and SkiaSharp, aiming to make it compatible with Linux, Mac, and PC. The tool will have features such as a drawing engine, timeline, shape tweening, symbol library, and scripting. The developer has also started a Patreon to support the project and plans to make it open-source. The goal is to create a full authoring environment that can import and edit old Flash files.
