I am trying to customize a charts_flutter graph - I want to display the current line graph value that the user is hovering over.
Is there any good documentation for charts_flutter or charts_common? The best thing I can find is the gallery:
https://google.github.io/charts/flutter/gallery.html
There seem to be some advanced examples in the "behaviors" section at the bottom. But I can't seem to find any documentation that describes all the available concepts.
