枚举值

名称	类型	默认值	说明
POINTS	—	'points'	Draw each point separately. If the Paint.stroke_cap is StrokeCap.ROUND, then each point is drawn as a circle with the diameter of the Paint.stroke_width, filled as described by the Paint (ignoring Paint.style). Otherwise, each point is drawn as an axis-aligned square with sides of length Paint.stroke_width, filled as described by the Paint (ignoring Paint.style).
LINES	—	'lines'	Draw each sequence of two points as a line segment. If the number of points is odd, then the last point is ignored. The lines are stroked as described by the Paint (ignoring Paint.style).
POLYGON	—	'polygon'	Draw the entire sequence of point as one line. The lines are stroked as described by the Paint (ignoring Paint.style).
