Struct BackdropKey 

pub struct BackdropKey(/* private fields */);

Flutter’s BackdropKey: backdrop filters sharing a key in one frame sample the backdrop once, as it is when the first of them is reached, instead of each sampling what the filters before it drew. A backend may reuse that one capture for all of them.
