Particle class

The Particle class represents a single particle in the particle network. It contains properties for position, velocity, color, size, and visibility.

Constructors

Particle({required Offset position, required Offset velocity, required Color color, required double size, bool isVisible = true}): Constructor to initialize the particle's properties.

acceleration ↔ Offset: Accumulated acceleration from forces applied during this frame.
getter/setter pair
color ↔ Color: The color of the particle.
getter/setter pair
defaultVelocity ↔ Offset: The default velocity of the particle, used to reset its speed.
getter/setter pair
hashCode → int: The hash code for this object.
no setterinherited
isVisible ↔ bool: A flag indicating whether the particle is visible within the viewport.
getter/setter pair
mass → double: The mass of the particle, affects how much force is needed to move it.
final
position ↔ Offset: The current position of the particle.
getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
size ↔ double: The size of the particle.
getter/setter pair
velocity ↔ Offset: The current velocity of the particle.
getter/setter pair
wasAccelerated ↔ bool: A flag indicating whether the particle was affected by touch interaction.
getter/setter pair

applyForce(Offset force) → void: Applies a force to the particle based on F = ma (a = F/m).
handleScreenBoundaries(Size bounds) → void: Handles collisions with the screen boundaries by reversing the velocity.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
inherited
update(Size bounds) → void: Updates the particle's position and velocity based on its current state.
updateVisibility(Size bounds) → void: Updates the visibility status of the particle based on its position.
