How to determine direction & amount dragged?

[jonjon1123]

Hi there!

I'm trying to figure out how I can use this library to get the direction the user is dragging (clockwise or counter-clockwise) and the amount they have dragged. I see there is onDragUpdate , but I am not sure how to use the PolarCoord from that function to determine the direction and amount dragged.

Any guidance would be greatly appreciated!

Hi, maybe you can use angle to determine the direction😄

Yeah, I eventually figured that out. Now I am trying to figure out how to determine the velocity of the dragging. I am trying to achieve something similar to this: https://fireship.io/snippets/circular-drag-flutter/. Maybe this lib could just expose onPanUpdate of the GestureDetector?
