Current version generates warnings when getting compiled with Flutter 3.

Hi, this widget has a screen-wide width.

It's incorrect, I cannot wrap the PageViewDotIndicator into Container because of it

Wanted result:

Actual result:

You probably should use shrink-wrap / IntrinsicWidth, to set an actual content size, instead of a MediaQuery size.

Hi, I'm facing a weird issue. I create a PageViewDotIndocator with currentPage = 0 and length = 12. I get the following stacktrace (see below).
The corresponding code in the PageViewDotIndocator code is:

double get maxScrollExtent => _maxScrollExtent!;

I did a quick investigation but didn't find any clue. Any idea? My enclosing layout probably causes it, but this Null check error should probably not happen...

Null check operator used on a null value

When the exception was thrown, this was the stack: 
#0      ScrollPosition.maxScrollExtent (package:flutter/src/widgets/scroll_position.dart:145:49)
#1      _PageViewDotIndicatorState._getOffsetForCurrentPosition (package:page_view_dot_indicator/src/indicator.dart:172:36)
#2      _PageViewDotIndicatorState.scrollToCurrentPosition (package:page_view_dot_indicator/src/indicator.dart:109:26)

Hi, we have been using the library for a while now and has been great. We have been seeing some crashes come back in our crash reporting however. Guessing it is unmounted or hasn't added the scroll controller into the scrollView yet.
