Sheet constructor

const Sheet({ Color? color, double? width, double? height, EdgeInsetsGeometry? margin, EdgeInsetsGeometry? padding, AlignmentGeometry? alignment, Decoration? decoration, Decoration? foregroundDecoration, Clip clipBehavior = Clip.none, BoxConstraints? constraints, Matrix4? transform, AlignmentGeometry? transformAlignment, })

A wrapper for the parameters that pertain to an Animated/Container.

If not provided an initializing color nor decoration, this field defaults to Colors.black so that a Foil.sheet has pixels to which it can mask its gradient.

Note that if provided a decoration, but that Decoration has no color, and no initializing color value was provided either, this Sheet may potentially result in a layer that has no pixels to which a Foil may be masked.

Implementation

const Sheet({
  Color? color,
  this.width,
  this.height,
  this.margin,
  this.padding,
  this.alignment,
  this.decoration,
  this.foregroundDecoration,
  this.clipBehavior = Clip.none,
  this.constraints,
  this.transform,
  this.transformAlignment,
}) : color = (color == null && decoration == null) ? Colors.black : color;
