model/particlemodel library

Particle data model and physics logic.

This library defines the Particle class and helper functions for calculating velocity and simulating particle behavior.

Classes

Particle

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

Functions

computeVelocity(Offset currentVelocity, Offset defaultVelocity, double speedThreshold) → Offset

Computes the velocity with gradual decay to return to the default velocity.

createMockParticle({Offset? position, Offset? velocity, Color? color, double? size}) → Particle

Utility function to create a mock particle for testing.
