cursor property Null safety
final
The mouse cursor for mouse pointers that are hovering over the region.
When a mouse enters the region, its cursor will be changed to the cursor. When the mouse leaves the region, the cursor will be decided by the region found at the new location.
The cursor defaults to MouseCursor.defer, deferring the choice of cursor to the next region behind it in hit-test order.
Implementation
final MouseCursor cursor;
