withConcurrencyControl abstract method
Future<bool>
withConcurrencyControl([
- ConcurrencyControl concurrencyControl = ConcurrencyControl.lastWriteWins
override
Saves the document to the database, resolving conflicts through ConcurrencyControl.
When write operations are executed concurrently, the last writer will win
by default. In this case the result is always true
.
To fail on conflict instead, pass ConcurrencyControl.failOnConflict to
concurrencyControl
. In this case, if the document could not be saved the
result is false
. On success it is true
.
