How do you properly implement request cancellation using Dio's own CancelToken, such as cancelling a search request the moment a user genuinely types a brand new different search query?

Dio's CancelToken lets you properly cancel an in progress network request at any given point, and passing that specific token into your request call and later calling its own cancel method causes that particular in progress request to genuinely be aborted, which is especially useful for a scenario like a live search feature, where you genuinely want to properly cancel a previous now genuinely outdated search request the very moment a user types a brand new different query, avoiding the possibility of an older, now genuinely stale response accidentally arriving after and incorrectly overwriting a considerably newer, more genuinely relevant result.

CancelToken cancelToken = CancelToken();
dio.get(url, cancelToken: cancelToken);

// When a new search begins
cancelToken.cancel('New search initiated');
