It looks like our overflow handling is pretty weird (if not just downright broken).

For instance, the following doesn't result in any overflow handling other than "clip", regardless of the overflow mode:

new Text(
  '''Lorem ipsum dolor sit amet, consectetur adipiscing elit.\n Phasellus sodales eros nec tortor maximus molestie.\nSed metus metus, viverra vel libero sed, commodo consequat ipsum. Sed commodo ultricies ligula, sed ultricies diam dignissim vitae. ''',
  softWrap: true,
  maxLines: 2,
  textAlign: TextAlign.start,
  overflow: TextOverflow.ellipsis,
),

I would expect that since there is more text to be displayed than the maxLines, that we do show the ellipsis at the end of the second line.

Also, if I remove the hard newlines, then the ellipsis does appear at the end of the second line, which is correct, but inconsistent. And if I then switch to overflow to fade, it fades the first line and the second, instead of just the second.
