Double precision issue on dynamic min-max value

[mqhamdam]

Is your feature request related to a problem? Please describe. Wanna Add Widget on Ruler (Using Custom Ruler not good, since have to calculate interval(steps by myself). When i change min max, i face with Double precision error. ex: 3.0 + 3.0 = 7. (just example or sometimes its like this: 7.942123212),

Describe the solution you'd like There are some packages that offer to customize the label.

Widget buildLabel(double value, int index) => MyCustomLabel(...);

Personally for calculating double values I use decimal package. So im try to use that here. but cannot.

I don't think its that difficult to add such feature. adding callback property in RulerStyle might be good solution. and if that callback is null, use default Widget.

Hi, @mqhamdam Can you add a proper example so that we can recreate the issue and fix it? cc : @Afroz-Shaikh

I fix the problem, but still think that it would be good to customize generated labels.
