Transaction set fails

[ConschiB]

First of all, really happy that transactions are now available in this package! Thanks a lot.

Describe the bug
When executing transaction.set(), the transaction crashes with following message:

'({(QueryDocumentSnapshot<Map<String, Object?>>) => Map<String, Object?> fromFirestore, (Map<String, Object?>) => Map<String, Object?> toFirestore})' is not a subtype of type '({(QueryDocumentSnapshot<Map<String, Object?>>) => dynamic fromFirestore, (dynamic) => Map<String, Object?> toFirestore})'

To Reproduce

await firestore.runTransaction((transaction) async {
    var otherIdDoc= await transaction.get(otherIdReference);
    transaction.update(otherIdReference, {'count': FieldValue.increment(1)});
    transaction.set(docRef, {'testkey': 'testvalue'});
    }

Expected behavior
Expected, that the transaction works.

Do you have the stacktrace and a bit more context around the issue? I can't reproduce it with what you gave us.

Tried both with withConverter and without, yet it's working fine for me.

I don't think I'll be able to move things forward without a more complete example and a stacktrace.

Passing test:

test('regression #77', () async {
  final otherIdReference = await initializeTest('otherId');
  await otherIdReference.set({'count': 0});

  final docRef = await initializeTest('simpleDocument');

  await firestore.runTransaction((transaction) async {
    await transaction.get(otherIdReference);
    transaction.update(otherIdReference, {
      'count': const FieldValue.increment(1),
    });
    transaction.set(docRef, {'testKey': 'testvalue'});
  });

  expect(
    await otherIdReference.get().then((s) => s.data()),
    {'count': 1},
  );

  expect(
    await docRef.get().then((s) => s.data()),
    {'testKey': 'testvalue'},
  );
});
