LinearGradient 继承自： Gradient

Creates a linear gradient from begin to end.

属性

名称	类型	默认值	说明
begin	Alignment	Alignment.CENTER_LEFT()	The offset at which stop 0.0 of the gradient is placed.
end	Alignment	Alignment.CENTER_RIGHT()	The offset at which stop 1.0 of the gradient is placed.
colors	list[ColorValue]	required	The colors the gradient should obtain at each of the stops. This list must contain at least two colors. If stops is provided, this list must have the same length as it.
tile_mode	GradientTileMode	GradientTileMode.CLAMP	How this gradient should tile the plane beyond in the region before begin and after end.
rotation	Optional[Number]	None	The rotation of the gradient in radians, around the center-point of its bounding box.
stops	Optional[list[Number]]	None	A list of values from 0.0 to 1.0 that denote fractions along the gradient. If provided, this list must have the same length as colors. If the first value is not 0.0, then a stop with position 0.0 and a color equal to the first color in colors is implied. If the last value is not 1.0, then a stop with position 1.0 and a color equal to the last color in colors is implied.
