SpringDescription class Null safety

Structure that describes a spring's constants.

Used to configure a SpringSimulation.

Constructors

SpringDescription({required double mass, required double stiffness, required double damping})
Creates a spring given the mass, stiffness, and the damping coefficient. [...]
const
SpringDescription.withDampingRatio({required double mass, required double stiffness, double ratio: 1.0})
Creates a spring given the mass (m), stiffness (k), and damping ratio (ζ). The damping ratio is especially useful trying to determining the type of spring to create. A ratio of 1.0 creates a critically damped spring, > 1.0 creates an overdamped spring and < 1.0 an underdamped one. [...]

Properties

damping double
The damping coefficient (c). [...]
final
hashCode int
The hash code for this object. [...]
read-only, inherited
mass double
The mass of the spring (m). The units are arbitrary, but all springs within a system should use the same mass units.
final
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
stiffness double
The spring constant (k). The units of stiffness are M/T², where M is the mass unit used for the value of the mass property, and T is the time unit used for driving the SpringSimulation.
final
