Hi! Have you considered also echarts library? It provides a large number of possibilities regarding charts. A simple json with the options has to be provided and the library does the rest. Here is the implementation in flutter: https://pub.dev/packages/flutter_echarts

I see that comment Since it is based on webview, this library has some inextricable instability and performance issues. We recommend the Flutter charting library Graphic as an alternative. and then looking at Graphic library I must say it looks impressive, especially nice Rows use it.

Well, I was thinking of this kind of answer 👍 Look forward to use try charts in Flet! Hope we will have it soon :) Do you have any idea when we will be able to try? Thanks a lot!

[FeodorFitsner]

Sure, still have to decide on the supported library :)

@FeodorFitsner .... Is this on roadmap ?? i.e. the Graphics library I assume

Google charts have been discontinued, yes. I'm also considering https://pub.dev/packages/fl_chart

Flutter Candlesticks packages, consider: (1) https://pub.dev/packages/interactive_chart or (2) https://pub.dev/packages/candlesticks

Nota bene: it would be a lot better if drawing objects can be user-drawn on top of the candlestick chart for so-called "technical analysis":

• horizontal, diagonal and vertical line drawing objects, and
• Quadratic Bézier curved drawing objects Each of those drawing objects should be able to adjusted and deleted later on.
