A widget that wraps child with scroll-wheel and on-screen +/− zoom controls that operate a Camera without rebuilding the child.

Constructors

GameCameraControls({Key? key, required Camera camera, required Widget child, double zoomStep = 0.1, double scrollZoomFactor = 0.1, bool showZoomLevel = false, bool enablePan = true, bool enablePinch = true}): Controls for camera over child: buttons and scroll steps of 0.1, mouse-drag pan and pinch zoom on, the zoom readout off, unless told otherwise. Every zoom is clamped to the camera's minZoom..maxZoom.
const

final
enablePan → bool: Enable mouse-drag to pan the camera (desktop).
final
enablePinch → bool: Enable two-finger pinch to zoom (touch).
final
hashCode → int: The hash code for this object.

runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
scrollZoomFactor → double: Zoom added (scrolling up) or taken away (scrolling down) per scroll event, whatever the event's size (mouse-wheel / trackpad).
final
showZoomLevel → bool: When true, displays the current zoom level between the +/− buttons.

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.
