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
constrained → bool
Whether the normal size constraints at this point in the widget tree are applied to the child.
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

Methods

createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → BetterInteractiveViewerState<BetterInteractiveViewer>
Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A short, textual description of this widget.
