Enum Gradient 

pub enum Gradient {
    Linear(LinearGradient),
    Radial(RadialGradient),
    Sweep(SweepGradient),
}

The three gradients and how they tile. Any of the three.

Variants

Linear(LinearGradient)

Along a line.

Radial(RadialGradient)

Round a centre.

Sweep(SweepGradient)

Turning round a centre.

Implementations

impl Gradient

pub fn colors(&self) -> &[Color]

The colours.

pub fn stops(&self) -> Option<&[f32]>

The stops as given.

pub fn tile_mode(&self) -> TileMode

What happens past the ends.

pub fn rotation(&self) -> f32

The turn about the box’s centre, in radians clockwise.

pub fn resolved_stops(&self) -> Vec<f32>

The stops in use: the ones given when there is one per colour, otherwise the colours spread evenly from 0 to 1 (gradient.dart’s _impliedStops).

pub fn sample(&self, t: f32) -> Color

The colour at t, between the colours either side of it, the end colours held past the stops. What the renderer bakes into its ramp; t is already tiled.

pub fn resolve(&self, direction: TextDirection) -> Gradient

The same gradient with its start and end made physical for direction.

pub fn scale(&self, factor: f32) -> Gradient

Every colour’s opacity times factor — the reference’s Gradient.scale, which is how a gradient on one side of a transition arrives or leaves.

pub fn lerp( a: Option<&Gradient>, b: Option<&Gradient>, t: f32, ) -> Option<Gradient>

The gradient t of the way to other (gradient.dart’s Gradient.lerp): two of the same kind with as many colours travel colour by colour, stop by stop and point by point; anything else fades one out and the other in.
