У меня возникает следующая проблема, когда я пытаюсь обновить баланс пользователя с помощью Firestore.instance.runTransaction, он выполняется, но затем, когда я пытаюсь выполнить ту же транзакцию для водителя, который собирается получить платеж от пользователя, и он НЕ выполняется.
Я пытался ввести обе транзакции в рамках одной и той же «Firestore.instance.runTransaction», но он явно не выполняет то, что мне нужно, поскольку полученный snapdata получен от пользователя, а не от драйвер.
Firestore.instance.runTransaction((Transaction tran) async {
await tran
.get(Firestore.instance
.collection('users')
.document(currentUser.uid))
.then((DocumentSnapshot snap) {
if (snap.exists) {
//Upgrade Balance of the User
tran.update(
Firestore.instance
.collection('users')
.document(currentUser.uid),
<String, dynamic>{
"Balance": snap.data['Balance'] - actcosto
}).catchError((err) => print(err));
}
});
});
Firestore.instance.runTransaction((Transaction tran) async {
await tran
.get(Firestore.instance
.collection('drivers')
.document(driverInputController.text))
.then((DocumentSnapshot snap) {
if (snap.exists) {
//Upgrade Balance of the driver
tran.update(
Firestore.instance
.collection('drivers')
.document(driverInputController.text),
<String, dynamic>{
"Balance": snap.data['Balance'] + actcosto
}).catchError((err) => print(err));
}
});
});
Я получаю эти ошибки
