setAlpha and setOpacity have no effect

[nfriend]

Summary

The setAlpha and setOpacity methods don't seem to have any effect on the TinyColor instance.

Possible cause

Looking at the source, I believe this is because these methods are defined like this:

TinyColor setAlpha(int alpha) {
  _color.withAlpha(alpha);
  return this;
}

However, the withAlpha method returns a new Color instance:

Returns a new color that matches this color with the alpha channel replaced with a (which ranges from 0 to 255).

so this doesn't actually change _color.

I just encounter the same issue. For workaround, do .color.withOpacity() or .color.withAlpha().…
