This logic of calculating offset is repeated multiple times in this file.
Can we just have a private shared function / getter for that instead of repeating it?

What do you think if we rename this new property to something like radialOffset?
Because commonly, we use the offset name for x and y in this project.

And there's an issue with our rendering when we only show a single section (360 degrees).
I don't know what's the best way to handle it (as it is an edge case), but I think ignoring it is just fine!
But please explain it in the docs that if there's only one section (360 degrees), this parameter is ignored.

Please fix those 3 comments. After that we're good to go! |

This Pull Request aims to implement the requested "exploding" pie chart sections of #2091.
Solution
Adding a [sectionOffset] parameter to [PieChartSectionData] and use that to calculate the offset in [drawSections] of [PieChartPainter].
