Description
Nice contribution! Thank you!
I'm updating the FLSpot with Timer.
The data and the chart will update, but the data in `touchTooltip` will not when I put the cursor still.
Should I write touchCallback?
I'm new in flutter.
please tell me how to write it?

Research direction
No source file or test is named. Reproduce the issue with fl_chart 0.35.0 and Flutter 2.2.0-11.0.pre.242 using a Timer that updates FLSpot while the cursor remains still, then trace the touchTooltip update path; done means the tooltip reflects the updated data without requiring a new touch gesture.
