How can i perform a rollback on a transactional DB?

hhtokpinar commented 2 years ago

Hi, You can perform a rollback just like below:

  await MyDbModel().batchStart();
  try {
    for (final obj in productList) {
      await obj.save(ignoreBatch: false); // Remember, if you use CRUD methods without the ignoreBatch parameter
                                         // it will be sent default with true, 
                                         // so it causes to perform the action out of the transaction 
    }
    final List<dynamic>? result = await MyDbModel().batchCommit();
  } catch (e) {
    MyDbModel().batchRollback();
  }
