# angularGradient(_:center:startAngle:endAngle:)

An angular gradient, which applies the color function as the
angle changes between the start and end angles, and anchored to
a relative center point within the filled shape.

```
@export(implementation) static func angularGradient(_ gradient: AnyGradient, center: UnitPoint = .center, startAngle: Angle, endAngle: Angle) -> some ShapeStyle
```

## Parameters

`gradient`

The gradient to use for filling the shape, providing the
colors and their relative stop locations.

`center`

The relative center of the gradient, mapped from the unit
space into the bounding rectangle of the filled shape.

`startAngle`

The angle that marks the beginning of the gradient.

`endAngle`

The angle that marks the end of the gradient.

## Discussion

An angular gradient is also known as a “conic” gradient. If
`endAngle - startAngle > 2π`, the gradient only draws the last complete
turn. If `endAngle - startAngle < 2π`, the gradient fills the missing
area with the colors defined by gradient stop locations at `0` and `1`,
transitioning between the two halfway across the missing area.

For example, an angular gradient used as a background:

```
ContentView()
    .background(.angularGradient(.red.gradient))
```

For information about how to use shape styles, see `ShapeStyle`.
