Support integer or string value formatting for PieChart (instead of float with decimals)

[mouness2020]

Hello 👋

I would like to know if the library currently supports, or if you plan to add, a feature for customizing the value format in PieChart / MultipleDonutChart.

Right now, the values are displayed as Float with decimals. My use case requires showing values as integers (e.g., 42 instead of 42.0) or even as custom strings.

Example expected behavior:
• Values displayed without decimals (e.g., 25 instead of 25.0)
• Option to pass a formatter (e.g., (Float) -> String) so the developer can control how values are rendered

This would make the charts more flexible in real-world scenarios where decimals are not desired.

Is this currently supported? If not, would you consider adding a valueFormatter parameter or similar customization option?

Thanks a lot for the great work on this library 🙏
