'Flutter: Is there any way to clean the contents in CustomPaint?
Recently I'm using CustomPaint and CustomPainter to draw line chart. I want to implement the function that, once I click a button, the lines in CustomPaint will disappear, just like no lines have been painted.
So what function should I put in the setState() of the button? Thank for your help.
