Enhancement of Data Point Interaction Capabilities for Improved Analytical Depth about fl_chart HOT 1 OPEN

Hi @yihong1120

• A callback mechanism when a data point is long-pressed, allowing developers to define custom actions:
  For the interactions, we already support customizations, you can override the touchCallback() function of LineTouchData receive the touch interactions and do whatever you want.
  (Don't forget to disable handleBuiltInTouches property to disable the default behaviour)

• It would add an interactive dimension to data presentation, making it more engaging and informative:
  I didn't understand this one clearly, but I think you're looking for a way to open another chart when user taps on something.
  So you can customize the interaction and do this at the moment.

• An expanded tooltip system that can display more detailed information, including metadata associated with data points:
  For this one, you can customize the showing tooltip and put some texts. We don't support customized widgets here, I agree that we can improve this part to support widgets inside the tooltip (follow this issue: #72)
  Check the below sample (source code is here) to see how you can customize the showing test.
  

  btw, I really appreciate your request

Let me what you think
