finalize abstract method
Computes the final value from a populated context
.
This is the last call made with the given context
, so this function may
also choose to clean up resources associated with the aggregate context.
The function must either return a bool
, num
, String
, List<int>
,
BigInt
or null
.
If invoking the function throws a Dart exception, the sql function will result with an error result as well.
Implementation
Object? finalize(AggregateContext<V> context);
