validateIntegrity method

@override VerificationContext validateIntegrity(Insertable<Group> instance, { bool isInserting = false, })

Validates that the given entity can be inserted into this table, meaning that it respects all constraints (nullability, text length, etc.).

Implementation

@override
VerificationContext validateIntegrity(
  Insertable<Group> instance, {
  bool isInserting = false,
}) {
  final context = VerificationContext();
  final data = instance.toColumns(true);
  if (data.containsKey('group_id')) {
    context.handle(

      groupId.isAcceptableOrUnknown(data['group_id']!, _groupIdMeta),
    );
  } else if (isInserting) {
    context.missing(_groupIdMeta);
  }
  if (data.containsKey('display_name')) {
