Constructors

ImageDrawable({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, required Image image, String? tag, Rect? sourceRect, bool flipped = false, double opacity = 1, double blurSigma = 0, ImageDrawableShape shape = ImageDrawableShape.rectangle, bool erasable = true})
Creates an ImageDrawable with the given image.
ImageDrawable.fittedToSize({required Offset position, required Size size, double rotationAngle = 0, Set<ObjectDrawableAssist> assists = const <ObjectDrawableAssist>{}, Map<ObjectDrawableAssist, Paint> assistPaints = const <ObjectDrawableAssist, Paint>{}, bool locked = false, bool hidden = false, required Image image, String? tag, Rect? sourceRect, bool flipped = false, double opacity = 1, double blurSigma = 0, ImageDrawableShape shape = ImageDrawableShape.rectangle, bool erasable = true})
Creates an ImageDrawable with the given image, and calculates the scale based on the given size. The scale will be calculated such that the size of the drawable fits into the provided size.

Properties

assistPaints → Map<ObjectDrawableAssist, Paint>
The paint to be used for each assist type.

Whether free-style erasing can affect this image.
final
flipped → bool
Whether the image is flipped or not.

opacity → double
The opacity used to draw the image, between 0 (transparent) and 1 (opaque).
final
position → Offset
The location of the object to be painted.
finalinherited
rotationAngle → double
The rotation of the object to be painted in radians.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scale → double
The scale of the object to be painted.
finalinherited
shape → ImageDrawableShape
The shape used to clip this image.
final
sourceRect → Rect
The source pixels from image that are drawn.
final
tag → String?
An optional application-defined tag for identifying this image.
