Cache management
Function overview
With the ZIM SDK, you can query the local cache file size of the currently logged-in user and clear the local cache.
Query cache
After creating a ZIM object and logging in, you can invoke the queryLocalFileCache interface and pass ZIMFileCacheQueryConfig to query the size of the cache for the current user locally.
The query result will be returned through the callback interface ZIMFileCacheQueriedResult.

try{
ZIMFileCacheQueryConfig config = ZIMFileCacheQueryConfig();
config.endTime = 0; // Query the cache size of the current user before this timestamp (UNIX).
// Fill in 0 or a value later than the current time to get the complete cache size of the current user.
ZIMFileCacheQueriedResult result = await ZIM.getInstance()!.queryLocalFileCache(config);
// Query cache result
} on PlatformException catch (onError) {
