ObjectGroupDrawable class

A transformable group of object drawables.

The child drawables use coordinates local to the center of the group. Create groups from painter-coordinate drawables with ObjectGroupDrawable.fromDrawables.

Constructors

ObjectGroupDrawable.fromDrawables({required Iterable<ObjectDrawable> drawables, double maxWidth = double.infinity, double rotationAngle = 0, double scale = 1, Set<ObjectDrawableAssist> assists = const <ObjectDrawableAssist>{}, Map<ObjectDrawableAssist, Paint> assistPaints = const <ObjectDrawableAssist, Paint>{}, bool locked = false, bool hidden = false})

Creates a group from drawables positioned in painter coordinates.

factory

ObjectGroupDrawable.fromLocalDrawables({required Iterable<ObjectDrawable> drawables, required Offset position, double rotationAngle = 0, double scale = 1, Set<ObjectDrawableAssist> assists = const <ObjectDrawableAssist>{}, Map<ObjectDrawableAssist, Paint> assistPaints = const <ObjectDrawableAssist, Paint>{}, bool locked = false, bool hidden = false})

Creates a group from children already expressed in group-local space.

Properties

assistPaints → Map<ObjectDrawableAssist, Paint>

The paint to be used for each assist type.

final, inherited

assists → Set<ObjectDrawableAssist>

The current assist lines the object has.

final, inherited

drawables → List<ObjectDrawable>

The objects contained by this group, in paint order.

final

erasable → bool

Whether free-style erasing can affect this drawable.

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

hidden → bool

Whether the drawable is hidden or not.

final, inherited

isHidden → bool

no setter, inherited

isNotHidden → bool

no setter, inherited

locked → bool

Defines if the object drawable is locked or not. If it is locked, it won't be movable, scalable or re-sizable using the UI.

final, inherited

min_scale → double

no setter, inherited

position → Offset

The location of the object to be painted.

final, inherited

rotationAngle → double

The rotation of the object to be painted in radians.

final, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

scale → double

The scale of the object to be painted.

Methods

copyWith({bool? hidden, Set<ObjectDrawableAssist>? assists, Map<ObjectDrawableAssist, Paint>? assistPaints, Offset? position, double? rotation, double? scale, bool? locked}) → ObjectGroupDrawable

Compares two ObjectDrawables for equality. Creates a copy of this but with the given fields replaced with the new values.

override

draw(Canvas canvas, Size size) → void

Draws the object on the provided canvas of size size.

override

drawAssists(Canvas canvas, Size size) → void

Draws any assist lines that the object has on canvas with size.

inherited

drawObject(Canvas canvas, Size size) → void

Abstract method to draw the object.

override

getSize({double minWidth = 0.0, double maxWidth = double.infinity}) → Size

Abstract method to get the size of the rendered object.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

toWorldDrawables() → List<ObjectDrawable>

Returns the children transformed back into painter coordinates.

Operators

operator ==(Object other) → bool

The equality operator.
