EffectWidget class

A widget that applies given Effect to a Widget. This widget is hardly used directly. Instead, use the extension methods provided by the effects to apply them to a Widget.

This widget does a parent lookup to find the EffectQuery widget to get the animation value. If no EffectQuery is found, the animation value is 1.

If an animation value is found, the Effect.lerp method is called to interpolate between two Effects. The resulting Effect is then applied to the child by calling Effect.apply.
