onSnapChanged property

Stream<SnapChangedInfo> onSnapChanged

Indicates that the snap candidate used by the GeometryEditor has changed.

The snap candidate may change when the pointer is moved close to or away from an existing snappable geometry or geometry guide. When this change results in a different snap candidate, or the edit position becoming unsnapped, this event fires.

Implementation

Stream<SnapChangedInfo> get onSnapChanged =>
    _snapChangedStreamController.stream;
