Do you had Example?

[I'm IT stupid]

I'm not very good at coding, and I'm trying to use your library.

I encountered "NoSuchMethod-Error":

do you have an example which I could look into it?
Or explanation on the usage
of the code

Here my code:
`import 'package:flutter/material.dart';
import 'package:speedometer/speedometer.dart';
class SpeedtoMeterLibary extends StatelessWidget{
@OverRide
Widget build(BuildContext context){
return Container(
child: Center(
child: SpeedOMeter(
start: 0,
end: 10,

),),
);

}
}
`
