NillGradients extension

A wrapper for retrieving transparent, empty Gradients appropriate for smooth GradientTweens.

Though all are transparent, consider that some have other properties set as well; such as the start and end angle for sweep both being ~0 or the radius of radial being 0.

The getter asNill is an extended property for an instantiated Gradient. It refers to the static method nillify, which may be called as:

NillGradients.nillify(Type type)
on

Properties

asNill → Gradient
Gradient get asNill => nillify( /* this. */ runtimeType);
no setter

Static Properties

linear → LinearGradient
An empty, transparent LinearGradient.
no setter
radial → RadialGradient
An empty, transparent RadialGradient.
no setter
stepsLinear → LinearSteps
An empty, transparent LinearSteps.
no setter
stepsRadial → RadialSteps
An empty, transparent RadialSteps.
no setter
stepsSweep → SweepSteps
An empty, transparent SweepSteps.
no setter
sweep → SweepGradient
An empty, transparent SweepGradient.
no setter

Static Methods

nillify(Type type) → Gradient?
Returns an empty, transparent Gradient of type matching type if one is available. Otherwise returns null such that asNill might generate a "nill" gradient by Gradient.copyWith(), which itself falls back to RadialGradient if type cannot be matched.
