directionality of the phone field

[AliEsmaeil]

The form field is displayed in LTR direction, the country pick icon on left while the actual number on right, despite the app is running in RTL mode, it's supposed to follow app directionality, i have tried setting textAlign: TextAlign.right but it didn't work neither setting Directionality above the whole PhoneFormField widget.

So, how can it be done, country pick icon (flag) on right as prefix and the phone number after it.

I got it, but it will be more flexible if it's controllable, so both directions work

I'm open to the idea, I'll review a PR.

What api do you have in mind ?
