startTransaction abstract method

FutureOr<void> startTransaction(
  1. Future run(
    1. QueryDelegate
    )
)

Start a transaction, which we assume implements QueryDelegate, and call run with the transaction.

If run completes with an error, rollback. Otherwise, commit.

The returned future should complete once the transaction has been commited or was rolled back.

Implementation

FutureOr<void> startTransaction(Future Function(QueryDelegate) run);
