Issue with the scrolling performance #5
Description
In case of using animateTo or even jumpTo function to scroll the table to some target area, every single cell on the way will be rendered.
This feature is completely unusable when using for jumping to some area of a long list (500 items and more) as it will render every single cell on the way to the target. I would expect at least jumpTo function to avoid rendering every single cell on the way.

Thank you for submitting this great issue, it's a problem, but the render things are handled by flutter framework itself, I just wrapped ListView widget, jumpTo method is also ListView's, so I have no idea to improve the performance of this package currently, do you have any ideas about this? thanks

I‘m a new to the Flutter ecosystem as we all are :) Unfortunately it's hard for me to purpose some solution right away. I will look into this issue a bit later and purpose something if I will come up with some ideas.

If I want to use the refresh function, do I need to determine the height of each cell?

Here is the relevant discussion, just for reference flutter/flutter#12319

@jizhigang no you shouldn't. height is necessary for calculating scroll offset related callbacks
