MouseTracker moved to rendering
Summary
#MouseTracker
and related symbols are moved from the gestures
package, resulting in error messages such as undefined classes or methods. Import them from rendering
package instead.
Context
#Prior to this change MouseTracker
was part of the gestures
package. This brought troubles when we found out that code related to MouseTracker
often wanted to import from the rendering
package.
Since MouseTracker
turned out to be more connected to rendering
than gestures
, we have moved it and its related code to rendering
.
Description of change
#The file mouse_tracking.dart
has been moved from the gestures
package to rendering
. All symbols in the said file have been moved without keeping backward compatibility.
Migration guide
#If you see error of "Undefined class" or "Undefined name" of the following symbols:
MouseDetectorAnnotationFinder
MouseTracker
MouseTrackerAnnotation
PointerEnterEventListener
PointerExitEventListener
PointerHoverEventListener
You should add the following import:
import 'package:flutter/rendering.dart';
Timeline
#Landed in version: 1.16.3
In stable release: 1.17
