deleteDocument abstract method

FutureOr<bool> deleteDocument(
  1. Document document, [
  2. ConcurrencyControl concurrencyControl = ConcurrencyControl.lastWriteWins
])

Deletes a document from this collection, 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 deleted the result is false. On success it is true.

Implementation

FutureOr<bool> deleteDocument(
  Document document, [
  ConcurrencyControl concurrencyControl = ConcurrencyControl.lastWriteWins,
]);
