Try this code, It works as you want

Future<void> loaderDialogNormal(BuildContext context) {
    showDialog(
        context: context,
        barrierDismissible: false,
        builder: (_) {
          return Center(
              child: Container(
                width: 100.0,
                height: 100.0,
                decoration: ShapeDecoration(
                  color: Colors.white,
                  shape: RoundedRectangleBorder(
                    borderRadius: BorderRadius.all(
                      Radius.circular(10.0),
                    ),
                  ),
                ),
                child: Center(
                  child: CircularProgressIndicator(
                    valueColor: AlwaysStoppedAnimation<Color>(
                        Colors.grey),
                  ),
                ),
