我已经试着调试这个问题近8天了。尝试了我在互联网/堆栈溢出/github上能找到的一切，仍然在同样的问题上。我已经完成了所有基本的故障排除(清洁，分解pod等)，甚至添加了googleservice信息。
在调试模式和android发布模式下没有问题。它只出现在iOS发布模式下的测试飞行和应用商店连接，但在模拟器/调试模式下工作。下面是堆栈跟踪:

下面也将是受影响的代码。我试图找出问题，当我评论docRef.get()方法时，它不再在试飞中崩溃了:
Future<List<dbResults>> results({
required String collectionKey,
required String documentKey,
required int count,
}) async {
FirebaseFirestore firestore = FirebaseFirestore.instance;
DocumentReference docRef =
firestore.collection(collectionKey).doc(documentKey);
List<dbResults> databaseResults = [];
await docRef.get().then((datasnapshot) {
if (datasnapshot.exists) {
try {
datbaseResults = datasnapshot.get('results');
// Additional Logic Here which won't even matter as
// it throws on docRef.get() itself (tried and tested)
}
} catch (_) {
if (kDebugMode) {
print("Error fetching game database results.");
}
}
}
});
return databaseResults;
}
颤振:3.3.9
Pubspec:
Cloud Firestore : 4.1.0
Firebase Core: 2.3.0
任何帮助将不胜感激!
我已经用尽了在线资源，提交了+30个构建只是为了解决这个问题。
我设法通过在执行查询之前对传递给函数的参数添加条件检查来修复它，如果它们不是空的。
只是有点奇怪，因为上面的函数甚至没有在应用程序启动时被调用，似乎Swift试图在应用程序启动和崩溃时调用该函数，但在Android发布和调试模式下，一切都是正常的。
对于所有和我在同一条船上的其他开发者，请从我的错误中吸取教训
也感谢Ali Nabel的帮助!
