Properties

allowNonCoveringScreenZoom bool
Allows the user to zoom out the child so that it is displayed smaller than the viewports width and height.
finalinherited
clipBehavior Clip
How to clip the content.
final
doubleTapToZoom bool
Allows the user to zoom by double tapping.
finalinherited
doubleTapZoomOutBehaviour DoubleTapZoomOutBehaviour
What should happen when the user double taps to zoom out.
final
hashCode int
The hash code for this object.
no setterinherited
interactionEndFrictionCoefficient double
Changes the deceleration behavior after a gesture.
finalinherited
key Key?
Controls how one widget replaces another widget in the tree.
finalinherited
maxScale double
The maximum allowed scale.
finalinherited
minScale double
The minimum allowed scale.
finalinherited
noMouseDragScroll bool
When true, disables drag scrolling with the mouse. Only mouse wheel zooming, and when enabled scrollbar zooming, is allowed then.
finalinherited
nonCoveringZoomAlignmentHorizontal HorizontalNonCoveringZoomAlign
The horizontal alignment of the non-covering zoom. Non covering zoom is the zoom that happens when the child is smaller than the viewport.
final
nonCoveringZoomAlignmentVertical VerticalNonCoveringZoomAlign
The vertical alignment of the non-covering zoom. Non covering zoom is the zoom that happens when the child is smaller than the viewport.
final
panAxis PanAxis
When set to PanAxis.aligned, panning is only allowed in the horizontal axis or the vertical axis, diagonal panning is not allowed.
finalinherited
panEnabled bool
If false, the user will be prevented from panning.
finalinherited
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
scaleEnabled bool
If false, the user will be prevented from scaling.
finalinherited
scaleFactor double
Determines the amount of scale to be performed per pointer scroll.
finalinherited
showScrollbars bool
Whether to show scrollbars.
finalinherited
transformationController TransformationController?
A TransformationController for the transformation performed on the child.
finalinherited
