There are two ways to control the handle visibilities, first from TextSelectionOverlay.handlesVisible and second from renderEditable.selectionStartHandleInViewport. This pr creates a _effectiveStartHandleVisibility to merge both api and feed it directly into _SelectionHandleOverlay.
The difference is the _SelectionHandleOverlay use a fadeintransition instead of visibility widget. There might be a really minor visual difference.

There is an issue (#52425) open about needing to do more fading to match native, so we probably need to make some changes there anyway.

I think this should have used glyphHeight instead of lineHeight. The size is used to pad gesture rect to make it easier to tap. This refactor also fixes it because the preferredLineHeight now contains the glyphHeight

It's great that you could get rid of an addPostFrameCallback 👍
