Properties
- alignment → Alignment?
-
The alignment of the child's origin, relative to the size of the box.
final
- alignPanAxis → bool
-
This property is deprecated, please use panAxis instead.
final
-
args
→ Map<
String, dynamic> -
finalinherited
- boundaryMargin → EdgeInsets
-
A margin for the visible boundaries of the child.
final
- child → JsonWidgetData
-
The child Widget that is transformed by InteractiveViewer.
final
- clipBehavior → Clip
-
If set to Clip.none, the child may extend beyond the size of the InteractiveViewer,
but it will not receive gestures in these areas.
Be sure that the InteractiveViewer is the desired size when using Clip.none.
final
- constrained → bool
-
Whether the normal size constraints at this point in the widget tree are
applied to the child.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- interactionEndFrictionCoefficient → dynamic
-
Changes the deceleration behavior after a gesture.
final
- maxScale → double
-
The maximum allowed scale.
final
- minScale → double
-
The minimum allowed scale.
final
- onInteractionEnd → (void Function(ScaleEndDetails)?)
-
Called when the user ends a pan or scale gesture on the widget.
final
- onInteractionStart → (void Function(ScaleStartDetails)?)
-
Called when the user begins a pan or scale gesture on the widget.
final
- onInteractionUpdate → (void Function(ScaleUpdateDetails)?)
-
Called when the user updates a pan or scale gesture on the widget.
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.
final
- panEnabled → bool
-
If false, the user will be prevented from panning.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- scaleEnabled → bool
-
If false, the user will be prevented from scaling.
final
- scaleFactor → double
-
Determines the amount of scale to be performed per pointer scroll.
final
- trackpadScrollCausesScale → bool
-
Whether scrolling up/down on a trackpad should cause scaling instead of
panning.
final
- transformationController → TransformationController?
-
A TransformationController for the transformation performed on the
child.
final
Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toJson(
) → Map< String, dynamic> -
Abstract function that concrete classes must implement. This must encode
the internal data model to a JSON compatible representation.
override
-
toString(
) → String -
Returns the string encoded JSON representation for this class. This will
remove all null values and empty collections from the returned string.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
