Properties

alignment → AlignmentGeometry
How to align the image within its bounds.
final
centerSlice → Rect?
The center slice for a nine-patch image.
final
checkTap → bool
Whether to check touches on a full tap (true), or onPanDown (false).
final
color → Color?
If non-null, this color is blended with each image pixel using colorBlendMode.
final
colorBlendMode → BlendMode?
Used to combine color with this image.
final
excludeFromSemantics → bool
Whether to exclude this image from semantics.
final
filterQuality → FilterQuality
Used to set the FilterQuality of the image.
final
fit → BoxFit?
How to inscribe the image into the space allocated during layout.
final
frameBuilder → ImageFrameBuilder?
Run against a real-world image, the previous example renders the following image.
final
gaplessPlayback → bool
Whether to continue showing the old image (true), or briefly show nothing (false), when the image provider changes.
final
hashCode → int
The hash code for this object.
no setterinherited
height → double?
If non-null, require the image to have this height.
final
imagePath → String
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
matchTextDirection → bool
Whether to paint the image in the direction of the TextDirection.
final
offCursor → SystemMouseCursor
Used to set the cursor type while hovering over a transparent portion of the image.
final
onCursor → SystemMouseCursor
Used to set the cursor type while hovering over an opaque portion of the image.
final
onHoverInside → Function?
final
onHoverOutside → Function?
final
onTapInside → Function?
final
onTapOutside → Function?
final
opacityThreshold → double
How opaque a pixel must to be before being recognized as part of the image. This is useful for images that have a partially-transparent border that shouldn't be clickable.
final
package → String?
final
repeat → ImageRepeat
How to paint any portions of the layout bounds not covered by the image.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scale → double?
final
semanticLabel → String?
A Semantic description of the image.
final
updateCursor → bool
Whether to show a different mouse cursor while hovering over the image (true), or prevent the cursor from changing at all while hovering over the image (false).
final
width → double?
If non-null, require the image to have this width.
final
