Spinner class

A one-cell animated glyph that reports ongoing work.

The spinner drives an AnimationController over the frame index range and restarts it from the beginning on completion, because the controller has no repeat mode. It advances one frame every interval.

A spinner animates for as long as it is mounted. Remove it from the tree when the work finishes rather than trying to stop it in place.

if (_loading) const Spinner()
