letSetOrNull<T> function
Let's you convert input to a Set type if possible, or returns null if
the conversion cannot be performed.
If filterNulls is true, the returned set will not contain any null
values. If nullFallback is provided, it will be used as a fallback value
for null values.
Implementation
Set<T>? letSetOrNull<T>(
dynamic input, {
bool filterNulls = false,
T? nullFallback,
}) {
return letIterableOrNull<T>(
input,
filterNulls: filterNulls,
nullFallback: nullFallback,
)?.toSet();
}
