Properties

alignment → AlignmentGeometry
How to align the image within its bounds.
finalinherited
centerSlice → Rect?
The center slice for a nine-patch image.
finalinherited
color → Color?
If non-null, this color is blended with each image pixel using colorBlendMode.
finalinherited
colorBlendMode → BlendMode?
Used to combine color with this image.
finalinherited
errorBuilder → ImageErrorWidgetBuilder?
A builder function that is called if an error occurs during image loading.
finalinherited
excludeFromSemantics → bool
Whether to exclude this image from semantics.
finalinherited
filterQuality → FilterQuality
The rendering quality of the image.
finalinherited
fit → BoxFit?
How to inscribe the image into the space allocated during layout.
finalinherited
frameBuilder → ImageFrameBuilder?
A builder function responsible for creating the widget that represents this image.
finalinherited
gaplessPlayback → bool
Whether to continue showing the old image (true), or briefly show nothing (false), when the image provider changes. The default value is false.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
height → double?
If non-null, require the image to have this height (in logical pixels).
finalinherited
image → ImageProvider<Object>
The image to display.
finalinherited
isAntiAlias → bool
Whether to paint the image with anti-aliasing.
finalinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
loadingBuilder → ImageLoadingBuilder?
A builder that specifies the widget to display to the user while an image is still loading.
finalinherited
matchTextDirection → bool
Whether to paint the image in the direction of the TextDirection.
finalinherited
opacity → Animation<double>?
If non-null, the value from the Animation is multiplied with the opacity of each image pixel before painting onto the canvas.
finalinherited
path → String
final
repeat → ImageRepeat
How to paint any portions of the layout bounds not covered by the image.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
semanticLabel → String?
A Semantic description of the image.
finalinherited
width → double?
If non-null, require the image to have this width (in logical pixels).
