Box class - assorted_layout_widgets library

Constructors

Box.new({Key? key, bool show = true, Color? color, EdgeInsetsGeometry? padding, double? width, double? height, AlignmentGeometry? alignment, Widget? child, bool removePaddingWhenNoChild = false, Decoration? decoration, DecorationPosition decorationPosition = DecorationPosition.background}): Box is something between a Container and a SizedBox. Unlike a Container it can be made const, so it's good for creating colored boxes, with or without padding:
const
Box.b({Key? key, bool show = true, Color? color, EdgeInsetsGeometry? padding, double? width, double? height, Alignment? alignment, Widget? child, bool removePaddingWhenNoChild = false, Decoration? decoration, DecorationPosition decorationPosition = DecorationPosition.background}): Adding .b to the box will make it blue. Use this for debugging purposes only. This constructor is marked as deprecated so that you don't forget to remove it.
const
Box.g({Key? key, bool show = true, Color? color, EdgeInsetsGeometry? padding, double? width, double? height, Alignment? alignment, Widget? child, bool removePaddingWhenNoChild = false, Decoration? decoration, DecorationPosition decorationPosition = DecorationPosition.background}): Adding .g to the box will make it green. Use this for debugging purposes only. This constructor is marked as deprecated so that you don't forget to remove it.
const
Box.gap(double gap): Creates a square box with gap by gap pixels. This may be used for small gaps between widgets. For example:
const
Box.r({Key? key, bool show = true, Color? color, EdgeInsetsGeometry? padding, double? width, double? height, Alignment? alignment, Widget? child, bool removePaddingWhenNoChild = false, Decoration? decoration, DecorationPosition decorationPosition = DecorationPosition.background}): Adding .r to the box will make it red. Use this for debugging purposes only. This constructor is marked as deprecated so that you don't forget to remove it.
const
Box.rand({Key? key, bool show = true, Color? color, EdgeInsetsGeometry? padding, double? width, double? height, AlignmentGeometry? alignment, Widget? child, bool removePaddingWhenNoChild = false, Decoration? decoration, DecorationPosition decorationPosition = DecorationPosition.background}): Use the Box.rand constructor to see when the widget rebuilds. It will change its color to a random one, whenever its build method is called. This constructor is marked as deprecated so that you don't forget to remove it.
const
Box.y({Key? key, bool show = true, Color? color, EdgeInsetsGeometry? padding, double? width, double? height, Alignment? alignment, Widget? child, bool removePaddingWhenNoChild = false, Decoration? decoration, DecorationPosition decorationPosition = DecorationPosition.background}): Adding .y to the box will make it yellow. Use this for debugging purposes only. This constructor is marked as deprecated so that you don't forget to remove it.

Properties

alignment → AlignmentGeometry?: final
child → Widget?: final
color → Color?: final
decoration → Decoration?: final
decorationPosition → DecorationPosition: final
hashCode → int: The hash code for this object.
no setterinherited
height → double?: final
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited

removePaddingWhenNoChild → bool: final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
show → bool: final
size → Size: Return the width/height of the box, if set. Note this is not the real size of the box, since it ignores the child and the layout.
no setter

Methods

add({double? width, double? height}) → Box: Returns a box with its width or height increased by width or height (or decreased if the given width or height are negative, clamped to zero).
build(BuildContext context) → Widget: Describes the part of the user interface represented by this widget.
override
copyWith({Key? key, bool? show, Color? color, EdgeInsetsGeometry? padding, double? width, double? height, AlignmentGeometry? alignment, bool? random, Decoration? decoration, DecorationPosition? decorationPosition, Widget? child}) → Box: Creates a copy of this Box but with the given fields replaced with the new values.
createElement() → StatelessElement: Creates a StatelessElement to manage this widget's location in the tree.
inherited
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
subtract({double? width, double? height}) → Box: Returns a box with its width or height decreased by width or height (clamped to zero).
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode: Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String: A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String: Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a one-line detailed description of the object.
inherited
toStringShort() → String: A short, textual description of this widget.

Operators

operator +(Object? obj) → Box: You can create boxes by adding a Box to one these types: bool, Color, EdgeInsetsGeometry, AlignmentGeometry, or Widget.
operator ==(Object other) → bool: The equality operator.
