existId method

Future<bool> existId(
  1. String idField
)

Checks if a document with the given ID exists in the collection. This method validates the ID format and checks for document existence. The idField should be a valid MongoDB ObjectId string representation. Parameters:

  • idField - String representation of the MongoDB ObjectId Returns true if the document exists, false if it doesn't exist or if the ID format is invalid. Example:
bool exists = await collection.existId('507f1f77bcf86cd799439011');
if (exists) {
  print('Document found');
}

Implementation

Future<bool> existId(String idField) async {
  var id = ObjectId.tryParse(idField);
  return existOid(id);
}
