some of the Option like Colorization, Waving is not working when the text is in multiple line.

Look at the animated text widgets in the package, likely in lib/src/. Find where colorization and waving animations are implemented and test them with multi-line text. Check if there are existing tests for multi-line behavior. The goal is to reproduce the issue and see where the animation logic breaks across lines.
