I found alot of folks onlile asking the same question, while the native platform allow modification it got me wondering why did the remove they parameter ?

Anyhow, a quick work around this would be using color filters like:

Widget withColor(Color color) => ColorFiltered(
      colorFilter: ColorFilter.mode(
        color,
        BlendMode.srcATop,
      ),
      child: const CupertinoActivityIndicator(),
    );
