MouseCursorResolver<R extends BaseTouchResponse> typedef
MouseCursorResolver<R extends BaseTouchResponse> =
MouseCursor Function(FlTouchEvent, R?)
It gives you the happened FlTouchEvent and existed R
data at the event's location,
then you should provide a MouseCursor to change the cursor at the event's location.
For example you can pass the SystemMouseCursors.click to change the mouse cursor to click.
Implementation
typedef MouseCursorResolver<R extends BaseTouchResponse> = MouseCursor Function(
FlTouchEvent,
R?,
);
