Particle class

Particle class to represent a single particle

This class is used to represent a single particle in the particle system. It contains the position, size, color, life, speed, angle, and rect of the particle.

Constructors

Particle(double dx, double dy, double size, Color color, double life, double speed, double angle, Rect rect)
const

Properties

angle → double
Value representing the angle of the particle in radians.
final
color → Color
The color of the particle.
final
direction → double
The angle of this offset as radians clockwise from the positive x-axis, in the range -pi to pi, assuming positive values of the x-axis go to the right and positive values of the y-axis go down.
no setterinherited
distance → double
The magnitude of the offset.
no setterinherited
distanceSquared → double
The square of the magnitude of the offset.
no setterinherited
dx → double
The x component of the offset.
no setterinherited
dy → double
The y component of the offset.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
isFinite → bool
Whether both components are finite (neither infinite nor NaN).
no setterinherited
isInfinite → bool
Returns true if either component is double.infinity, and false if both are finite (or negative infinity, or NaN).
no setterinherited
life → double
Value between 0 and 1 representing the life of the particle.
final
rect → Rect
The rect where the particle is located.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
size → double
The size of the particle.
final
speed → double
Value representing the speed of the particle in pixels per frame.

Methods

copyWith({double? dx, double? dy, double? size, Color? color, double? life, double? speed, double? angle, Rect? rect}) → Particle
Copy the particle with new values
moveToRandomAngle() → Particle
Move the particle
moveWithAngle(double angle) → Particle
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
scale(double scaleX, double scaleY) → Offset
Returns a new offset with the x component scaled by scaleX and the y component scaled by scaleY.
inherited
toString() → String
A string representation of this object.
inherited
translate(double translateX, double translateY) → Offset
Returns a new offset with translateX added to the x component and translateY added to the y component.

Operators

operator %(double operand) → Offset
Modulo (remainder) operator.
inherited
operator &(Size other) → Rect
Rectangle constructor operator.
inherited
operator *(double operand) → Offset
Multiplication operator.
inherited
operator +(Offset other) → Offset
Binary addition operator.
inherited
operator -(Offset other) → Offset
Binary subtraction operator.
inherited
operator /(double operand) → Offset
Division operator.
inherited
operator <(OffsetBase other) → bool
Less-than operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are smaller than the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.
inherited
operator <=(OffsetBase other) → bool
Less-than-or-equal-to operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are smaller than or equal to the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.
inherited
operator ==(Object other) → bool
Compares two Offsets for equality.
inherited
operator >(OffsetBase other) → bool
Greater-than operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are bigger than the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.
inherited
operator >=(OffsetBase other) → bool
Greater-than-or-equal-to operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are bigger than or equal to the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.
inherited
operator unary-() → Offset
Unary negation operator.
inherited
operator ~/(double operand) → Offset
Integer (truncating) division operator.
