JumpingDots Speed Android & iOS

Hi, I have an issue with JumpinDotsIndicator Widget.

In Android the dots are like ten times faster than in iOS, is there any solution? I don't want to differentiate between Android and iOS version just for this issue.

PS: In my project is JumpingDots but I've checked and it happened to all the animations

My class code:

class LoadingScreen extends StatelessWidget {
const LoadingScreen({Key key}) : super(key: key);

@OverRide
Widget build(BuildContext context) {
return SizedBox.expand(
child: Container(
child: Padding(
padding: const EdgeInsets.all(36.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
JumpingDotsProgressIndicator(
milliseconds: 250,
fontSize: 48.0,
color: Colors.white,
),
SizedBox(height: 16.0),
// LoadingIndicator(indicatorType: Indicator.values[16]),
Text(
'Loading...,
style: kWhiteTitleStyle,
textAlign: TextAlign.center,
)
],
),
),
));
}
}

JumpingDots not Working

child: JumpingDotsProgressIndicator( fontSize: 30.0, color: Colors.blue, numberOfDots: 5, ),

this is my code snippet, but Jumping dots is not working.

High CPU usage

Hi, I'm encountering high cpu usage when using JumpingDotsProgressIndicator .

I think there's an infinite loop without delay.

This widget is not vertically Centered.

In the Build Method there is a SizedBox with Height = 1.5 * fontSize.
I have fontsize = 100, so my Height is 150pixels.
Inside of it there is a Row.
However when you wrap the whole widget in a Container and give color you can see that it is in the bottom of the container.
Could you implement a way to Center vertically?

Null safety

Thanks for the great package!

Do you plan to make a null safe update of the package?
