snappy constant

SpringDescription const snappy

Tension 750, friction 50. RK4 settle ~480ms. Focus, resize, drag transition, scrim, layout transforms. Barely underdamped (ζ=0.91) — very subtle overshoot then settle. Most common spring for interactive elements.

Implementation

static const snappy = SpringDescription(mass: 1, stiffness: 750, damping: 50);
