deviceEventDispatcher property Null safety
read / write
An object to which real device events should be routed.
Normally, device events are silently dropped. However, if this property is set to a non-null value, then the events will be routed to its HitTestDispatcher.dispatchEvent method instead.
Events dispatched by TestGesture are not affected by this.
Implementation
HitTestDispatcher? deviceEventDispatcher;
