SpringDescription class
Structure that describes a spring's constants.
Used to configure a SpringSimulation.
Constructors
- SpringDescription({double mass, double stiffness, double damping })
-
Creates a spring given the mass, stiffness, and the damping coefficient. [...]
const
- SpringDescription.withDampingRatio({double mass, 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
- 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
- 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
- hashCode → int
-
The hash code for this object. [...]

- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
toString(
) → String -
Returns a string representation of this object.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed. [...]

dynamic other) → bool -
The equality operator. [...]
