Methods
-
drawParticle(
Canvas canvas, Size size) → void -
Allow subclasses to define their own draw method
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
paint(
Canvas canvas, Size size) → void -
inherited
-
pushTrailPosition(
Offset pos) → void -
inherited
-
resetLifetimeState(
) → void -
Resets lifetime-driven runtime state (color/scale/opacity/trail) back to
start values. Used when a pooled particle slot is reused for a new burst.
inherited
-
rotate(
Canvas canvas, double cx, double cy) → void -
inherited
-
toString(
) → String -
