CameraControls class Widgets

Feeds pointer, scroll, and keyboard input to a CameraController.

Wrap the widget showing the scene (typically a SceneView). Drag rotates or looks, a two-finger gesture pinches to dolly and moves to pan, the scroll wheel dollies, and while focused the keyboard drives movement. The controller must be attached to a scene node (with a CameraComponent) so it can drive that node; this widget only forwards input to it.

This is one input adapter, not the only way to drive a controller: the controller's own intent methods (orbitBy, dollyBy, look, ...) can be called from any source, so an application with its own input handling can skip this widget.

Constructors

CameraControls({Key? key, required CameraController controller, bool enabled = true, bool autofocus = true, required Widget child})
Wraps child, routing its input to controller.
const

Properties

autofocus → bool
Whether to take keyboard focus on mount so keys work without a click.
final
child → Widget
The widget showing the scene.
final
controller → CameraController
The controller to drive. Attach the same instance to a scene node.
final
enabled → bool
Whether input is forwarded. When false the child still shows but input is ignored (and held keys are released).
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
