physics library

Simple one-dimensional physics simulations, such as springs, friction, and gravity, for use in user interface animations.

To use, import package:flutter/physics.dart.

Classes

BoundedFrictionSimulation: A FrictionSimulation that clamps the modeled particle to a specific range of values.
ClampedSimulation: A simulation that applies limits to another simulation. [...]
FrictionSimulation: A simulation that applies a drag to slow a particle down. [...]
GravitySimulation: A simulation that applies a constant accelerating force. [...]
ScrollSpringSimulation: A SpringSimulation where the value of x is guaranteed to have exactly the end value when the simulation isDone().
Simulation: The base class for all simulations. [...]
SpringDescription: Structure that describes a spring's constants. [...]
SpringSimulation: A spring simulation. [...]
Tolerance: Structure that specifies maximum allowable magnitudes for distances, durations, and velocity differences to be considered equal.

nearEqual(double a, double b, double epsilon) → bool: Whether two doubles are within a given distance of each other. [...]
nearZero(double a, double epsilon) → bool: Whether a double is within a given distance of zero. [...]

SpringType: The kind of spring solution that the SpringSimulation is using to simulate the spring. [...]
