Fl_chart: [LineChart] Proposal: TooltipItem with Widget child.

[jamesblasco]

Tooltips in line chart are a really cool feature, but would be even cooler if we could customize it a bit more.

Making the child a widget become very versatile. It would allow to add a title with a custom style below the spot value or even an image.
