completed property
Provides a Future which will be completed once the transaction has completed.
The future will error if an error occurs on the transaction or if the transaction is aborted.
Implementation
Future<Database> get completed {
var completer = new Completer<Database>();
this.onComplete.first.then((_) {
completer.complete(db);
});
this.onError.first.then((e) {
completer.completeError(e);
});
this.onAbort.first.then((e) {
// Avoid completing twice if an error occurs.
if (!completer.isCompleted) {
completer.completeError(e);
}
});
return completer.future;
}
