Struct Tolerance 

pub struct Tolerance {
    pub velocity: f64,
    pub distance: f64,
}

The velocity/distance thresholds below which a ballistic simulation is considered settled — Flutter’s Tolerance, produced by toleranceFor.

Fields

velocity: f64

Velocity (px/s) below which motion counts as stopped.

distance: f64

Distance (logical px) below which position counts as arrived.

Implementations

impl Tolerance

pub fn for_device_pixel_ratio(dpr: f64) -> Tolerance

Flutter’s toleranceFor formula exactly: velocity tolerance tightens (and distance tolerance loosens) as dpr grows, since a physical pixel covers less logical distance on a denser screen.
