Any way to separate the SwipeLayout class?

Currently, SwipeLayout has almost 2k lines. It was too big and difficult to read & maintain. Could the author help separate the logics here to make it cleaner? Thanks.

Start by locating the SwipeLayout class and reading its nearly 2,000 lines to identify the responsibilities that are mixed together. Define a separation plan with clear boundaries before changing code; done means the logic is split into smaller, maintainable units without changing the layout's behavior.
