A simple way to add pagination to your Flutter app. How to use:

    NumberPagination(
        onPageChanged: (int pageNumber) {
        setState(() {
            _counter = pageNumber;
        });
        },
        pageTotal: 50,
        pageInit: _counter, // picked number when init page
        colorPrimary: Colors.blue,
        colorSub: Colors.white,
        threshold: 7,
    ),
