No need to use ext libraries

        Polygon poly = ....;
        onTap: (tapPosition,latlng) {
          setState(() {
              if(poly.boundingBox.contains(latlng)){
                log("point inside the edge")
              }
          });
        },

You can use point_in_polygon package and simply pass your point and point of polygon.

Poly.isPointInPolygon(pointToCheckIfInPolygon, pointsOfPolygon)
