I am a bit confused about drawing polylines on 
Canvas
. I see that the 
DrawScope.drawPath
function accepts 
Path
as a parameter. However, I also found a quite convenient path builder function 
PathData
which returns 
List<PathNode>
. Can I somehow pass that list of path nodes to 
DrawScope.drawPath
, i.e., construct a 
Path
from 
List<PathNode>
?
Okay, I found that I can do this:
Copy code
val path = Path().apply {
    moveTo(1f, 2f)
    lineTo(3f, 4f)
    lineTo(5f, 7f)
}

drawPath(path, Color.Red)
Now the issue is that the path has a fill (either with non-zero or even-odd 
PathFillType
). How can I make a path without any fill?
I found a way to do this:
Copy code
drawCanvas { canvas, size ->
    canvas.drawPath(path, Paint().apply {
        color = Color.Red
        style = PaintingStyle.stroke
        strokeWidth = 3
    })
}
Note: 
drawCanvas
is a function in the 
DrawScope
, so it should be inside 
Canvas
composable.

there is a style param on drawPath where you can provide Stroke with your params instead of the default Fill
