removeEntryFor method

@override Future<void> removeEntryFor(String key)

Remove the commit entry for key, if one exists. The log holds at most one entry per atKey, so at most one entry is removed; removing none is not an error. Used by the skipCommit write paths: a write that must leave no commit entry also scrubs the key's previous entry, otherwise sync would keep serving a stale entry for a record whose latest change was deliberately uncommitted.

key takes the same form that commit accepts on the same backend.

Implementation

@override
Future<void> removeEntryFor(String key) async => purgeSync(key);
