Is there an existing issue for this?

Use case

CupertinoTextSelectionToolbar is very different from the native implementation, some problems are:

1. When changing pages, the whole content fades to the divider color instead of the actual background color;
2. Font size should be slightly bigger
3. There's no horizontal scroll to change pages
4. The whole layout instantly changes width when changing pages
5. The last page shows a disabled nextButton, when natively the button is hidden on the last page.

Here is a comparison between the current flutter cupertino toolbar and the native one.

Proposal

Flutter should improve these areas to have a better toolbar on iOS.

The good news is that I'm requesting to be assigned this issue as I already fixed all these problems and will be creating a PR shortly. 😁
