SheenChapterList class Music

The chapters of a long recording as rows: the title, where it starts and how long it is, the chapter playing in the accent colour, the ones already heard dimmed. A tap picks a chapter.

It is a column, not a scroll view: put it in the sheet or page that scrolls.

Constructors

SheenChapterList({Key? key, required List<SheenChapter> chapters, required Duration position, Duration? length, ValueChanged<SheenChapter>? onSelected})
chapters with the one holding position marked. Each row shows how long its chapter is, and where it starts under the title (a start time alone on the right reads as a length: "0:00:00" looked like an empty chapter).
