Particle class abstract
Base class implementing common behavior for all the particles.
Intention is to follow the same "Extreme Composability" style as seen across the whole Flutter framework. Each type of particle implements some particular behavior which then could be nested and combined to create the experience you are looking for.
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- lifespan → double
-
Getter for the current lifespan of this Particle.
no setter
- progress → double
-
Getter which should be used by subclasses to get overall progress.
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- shouldRemove → bool
-
This method will return true as soon as the particle reaches the end of
its lifespan.
no setter
Methods
-
accelerated(
{required Vector2 acceleration, Vector2? position, Vector2? speed}) → Particle -
Wraps this particle with a
AcceleratedParticle. -
moving(
{required Vector2 to, Vector2? from, Curve curve = Curves.linear}) → Particle -
Wraps this particle with a
MovingParticle. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
render(
Canvas canvas) → void - Should render this Particle to given Canvas.
-
rotated(
double angle) → Particle -
Rotates this particle to a fixed angle in radians using the
RotatingParticle. -
rotating(
{double from = 0, double to = pi}) → Particle -
Rotates this particle from a given angle to another one in radians
using
RotatingParticle. -
scaled(
double scale) → Particle -
Wraps this particle with a
ScaledParticle. -
scaling(
{double to = 0}) → ScalingParticle -
Wraps this particle with a
ScalingParticle. -
setLifespan(
double lifespan) → void - A control method allowing a parent of this Particle to pass down it's lifespan.
-
toString(
) → String -
A string representation of this object.
inherited
