Maybe rename to EditableText does not derive selection color from DefaultSelectionStyle

LGTM 👍
Just as a thought, what if we passed a transparent Color as selectionColor instead of null?

Nit: Is it relevant to say "Regression test for #103341" here and elsewhere?

That works too. Though if someone explicitly passes null as selectionColor to EditableText. I think they would expect no selection to be painted, where as now it defaults to the color defined by DefaultSelectionStyle.of(context).

I don't have a strong opinion on this, but if I were to redesign this again, passing null as color means disabling the selection seems to be a weird API, In that case I would probably throw if the color is null

I agree, though another small difference between null and Colors.transparent is that the TextHighlightPainter skips painting all together when the selectionColor is null vs when it is Colors.transparent it will still paint some values.
