validateIntegrity method
- Insertable<
CacheRow> instance, { - bool isInserting = false,
override

Implementation
@override
VerificationContext validateIntegrity(
Insertable<CacheRow> instance, {
bool isInserting = false,
}) {
final context = VerificationContext();
final data = instance.toColumns(true);
if (data.containsKey('checksum')) {
context.handle(
_checksumMeta,
checksum.isAcceptableOrUnknown(data['checksum']!, _checksumMeta),
);
} else if (isInserting) {
context.missing(_checksumMeta);
}
return context;
