AcceleraxLayer class

A Layer in an XL. These by themselves are not Widgets.

Each Layer serves as a blueprint for transformations to its child within its parent and contains all the animatable properties. Keep in mind that axes will depend on device orientation.

The xOffset, yOffset, xRotation, yRotation, and zRotationByX are reactionary to their respective axes when it comes to AccelerometerEvents.

The zRotationByGyro, however, is a secondary Z-axis "spin" factor whose core value is derived from GyroscopeEvents.

  • This means that samples from the gyroscope for Z-axis "spins" with this property, according to Normalization.samplingRate, will spike but return to 0 immediately once the device has finished "spinning".

Properties

child → Widget
The widget below this widget in the tree.
finalinherited
debugTypicalAncestorWidgetClass → Type
Describes the RenderObjectWidget that is typically used to set up the ParentData that applyParentData will write to.
no setterinherited
debugTypicalAncestorWidgetDescription → String
Describes the RenderObjectWidget that is typically used to set up the ParentData that applyParentData will write to.
no setterinherited
dimensionalOffset → double
The intensity of the 3D change in perspective activated by enable3d. Defaults to 0.001.
finalinherited
enable3d → bool
Whether the child should be transformed with a 3D perspective effect.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
offset → Offset
The offset at which to paint the child in the parent's coordinate system.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
xOffset → double
How much the child should translate on the horizontal axis when a pointer event occurs.
finalinherited
xRotation → double
How much the child should rotate on the X-axis when a pointer event occurs. The nature of the rotation is up-down.
finalinherited
yOffset → double
How much the child should translate on the vertical axis when a pointer event occurs.
finalinherited
yRotation → double
How much the child should rotate on the Y-axis when a pointer event occurs. The nature of the rotation is left-right.
finalinherited
zRotation → double
How much the child should rotate on the Z-axis when a horizontal pointer event occurs.
finalinherited
zRotationByGyro → double
How much the child should spin on the z axis when a z-axis gyroscope movement is sampled.
