formating numbers according to app's localization

**Describe the bug**
I have used LineChart in my project. But when user changes app's lanuage to something else than device's language, it doesn't translate or format numbers according to new one. I cannot find any property which i can give current app's language. If there is such thing, please let me know.

**Screenshots**
Here is device lang is russan, but app's lang is english.

**Versions**
- which version of the Flutter are you using? => Flutter 3.10.0
- which version of the FlChart are you using? => fl_chart: ^0.61.0

Start with the LineChart entry point and reproduce the behavior using Flutter 3.10.0 and fl_chart 0.61.0 while the app language differs from the device language. Trace how chart numbers are formatted and identify whether the current API exposes app-locale input; done means the chart follows the app locale or the supported limitation is clearly documented.
