Sheet class Null safety

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.

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. [...]

Properties

alignment AlignmentGeometry?
See Container.alignment.
final
clipBehavior Clip
Default is Clip.none which allows visual overflow.
Clipping has performance implications. See also: Container.clipBehavior.
final
color Color?
Background color. 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. [...]
final
constraints BoxConstraints?
Constrain dimensions.
final
decoration Decoration?
A Decoration, likely a BoxDecoration or ShapeDecoration, to apply as a background. This can define color, shape, border and more.
final
foregroundDecoration Decoration?
A Decoration, likely a BoxDecoration, to apply as a decoration in the front layer of presentation.
final
hashCode int
The hash code for this object. [...]
read-only, inherited
height double?
Provide intrinsic dimensions.
final
margin EdgeInsetsGeometry?
EdgeInsets to apply on the outside edge, condensing the space available to the container and content within it.
final
padding EdgeInsetsGeometry?
EdgeInsets to apply on the inner edge, padding the content within.
final
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
transform Matrix4?
A Matrix4 is a complex array of 0s or other values that describe how to translate, rotate, offset, shift perspective, or otherwise transform the widget.
final
transformAlignment AlignmentGeometry?
If providing a transform, optionally specify how to align it.
final
width double?
Provide intrinsic dimensions.
