当使用发布 apk 时，Dart AOT 编译器 (TFA) 删除了一些代码

Question

我想给一些朋友一个我的项目的 apk 版本来测试它。 在我的 IDE 上，我的项目运行良好，可能存在一些错误，但主要概念是可行的。

他们报告了一些在我这边没有发生的错误，所以我尝试了 release apk，当我触发 some specifics methods 时出现此错误：

[ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: Attempt to execute code removed by Dart AOT
compiler (TFA)

this is the error message

触发此错误的方法有：

Future askFriends(String friendName) async {
    print("Send FRIENDS Request");
    print(friendName);
    await _fs
        .collection("Users")
        .document(await pbd.getEmail(friendName))
        .collection("FriendsRequest")
        .document(await pbd.getUserName())
        .setData({
      "profilPicture": await pbd.getProfilePicture(),
      "friendName": await pbd.getUserName(),
      "friendEmail": currentUserEmail,
    });
  }

void acceptFriends(String friendName, String profilPicture) async {
    var reference = randomAlphaNumeric(20);
    String friendEmail = await pbd.getEmail(friendName);
    String userName = await pbd.getUserName();
    print("ADD FRIENDS");
    await _fs
        .collection("Users")
        .document(currentUserEmail)
        .collection("FriendsRequest")
        .document(friendName)
        .delete();
    await _fs
        .collection("Users")
        .document(friendEmail)
        .collection("Friends")
        .document(userName)
        .setData({
      "profilPicture": await pbd.getProfilePicture(),
      "friendName": userName,
      "friendEmail": currentUserEmail,
      "chatReference": reference,
    });
    await _fs
        .collection("Users")
        .document(currentUserEmail)
        .collection("Friends")
        .document(friendName)
        .setData({
      "profilPicture": profilPicture,
      "friendName": friendName,
      "friendEmail": friendEmail,
      "chatReference": reference,
    });
    _fs.collection("PrivateChat").document(reference).setData({
      "users": [userName, friendName]
    });
    _fs.collection("Users").document(currentUserEmail).updateData({
      "friends": await pbd.getUserFriendsNumber(currentUserEmail) + 1,
    });
    _fs.collection("Users").document(friendEmail).updateData({
      "friends": await pbd.getUserFriendsNumber(friendEmail) + 1,
    });
  }

同样在运行“Flutter run --release -v”时 关于它只返回的 AOT：

在 firestore 上写入 read 不是问题，因为 apk 中使用的许多方法都使用 Cloud Firestore 并且完全可以。

Flutter doctor

My Pubspec.yaml

Build.grade[APP-level]

Build.grade[Project-level]

我在网上只发现了一个类似的问题： Attempt to execute code removed by Dart AOT compiler (TFA), how to troubleshoot this issue

所以我尝试删除构建目录，flutter clean，flutter pub缓存修复，重新创建一个新的flutter项目，导入我项目的所有组件。改变flutter的通道。

另外写“Flutter clean”给这个警告。

Failed to remove build. A program may still be using a file in the directory or the directory itself. To find and stop such a program, see:
https://superuser.com/questions/1333118/cant-delete-empty-folder-because-it-is-used

我已按照说明进行操作，但没有任何改变。

谢谢你帮助我。

好的，所以我通过以下方式解决了这个问题：

-将颤振通道更改为稳定

-更改内部版本号

-更改具体方法：

似乎（cloud firestore 有一些问题（与 IDE 上的项目没有提供相同的结果）。

之前的方法：

Future askFriends(String friendName) async {
    print("Send FRIENDS Request");
    print(friendName);
    await _fs
        .collection("Users")
        .document(await pbd.getEmail(friendName))
        .collection("FriendsRequest")
        .document(await pbd.getUserName())
        .setData({
      "profilPicture": await pbd.getProfilePicture(),
      "friendName": await pbd.getUserName(),
      "friendEmail": currentUserEmail,
    });
  }

void acceptFriends(String friendName, String profilPicture) async {
    var reference = randomAlphaNumeric(20);
    String friendEmail = await pbd.getEmail(friendName);
    String userName = await pbd.getUserName();
    print("ADD FRIENDS");
    await _fs
        .collection("Users")
        .document(currentUserEmail)
        .collection("FriendsRequest")
        .document(friendName)
        .delete();
    await _fs
        .collection("Users")
        .document(friendEmail)
        .collection("Friends")
        .document(userName)
        .setData({
      "profilPicture": await pbd.getProfilePicture(),
      "friendName": userName,
      "friendEmail": currentUserEmail,
      "chatReference": reference,
    });
    await _fs
        .collection("Users")
        .document(currentUserEmail)
        .collection("Friends")
        .document(friendName)
        .setData({
      "profilPicture": profilPicture,
      "friendName": friendName,
      "friendEmail": friendEmail,
      "chatReference": reference,
    });
    _fs.collection("PrivateChat").document(reference).setData({
      "users": [userName, friendName]
    });
    _fs.collection("Users").document(currentUserEmail).updateData({
      "friends": await pbd.getUserFriendsNumber(currentUserEmail) + 1,
    });
    _fs.collection("Users").document(friendEmail).updateData({
      "friends": await pbd.getUserFriendsNumber(friendEmail) + 1,
    });
  }

现在的方法：

Future askFriends(String friendName) async {
    print("Send FRIENDS Request");
    String userName = await pbd.getUserName();
    String friendEmail = await pbd.getEmail(friendName);
    String profilPicture = await pbd.getProfilePicture();
    print(friendName);
    await _fs
        .collection("Users")
        .document(friendEmail)
        .collection("FriendsRequest")
        .document(userName)
        .setData({
      "profilPicture": profilPicture,
      "friendName": userName,
      "friendEmail": currentUserEmail,
    });
  }

void acceptFriends(String friendName, String profilPicture) async {
    var reference = randomAlphaNumeric(20);
    String friendEmail = await pbd.getEmail(friendName);
    String userName = await pbd.getUserName();
    String userProfilPicture = await pbd.getProfilePicture();
    int userFriends = await pbd.getUserFriendsNumber(currentUserEmail);
    int friendFriends = await pbd.getUserFriendsNumber(friendEmail);
    print("ADD FRIENDS");
    await _fs
        .collection("Users")
        .document(currentUserEmail)
        .collection("FriendsRequest")
        .document(friendName)
        .delete();
    await _fs
        .collection("Users")
        .document(friendEmail)
        .collection("Friends")
        .document(userName)
        .setData({
      "profilPicture": userProfilPicture,
      "friendName": userName,
      "friendEmail": currentUserEmail,
      "chatReference": reference,
    });
    await _fs
        .collection("Users")
        .document(currentUserEmail)
        .collection("Friends")
        .document(friendName)
        .setData({
      "profilPicture": profilPicture,
      "friendName": friendName,
      "friendEmail": friendEmail,
      "chatReference": reference,
    });
    _fs.collection("PrivateChat").document(reference).setData({
      "users": [userName, friendName]
    });
    _fs.collection("Users").document(currentUserEmail).updateData({
      "friends": userFriends + 1,
    });
    _fs.collection("Users").document(friendEmail).updateData({
      "friends": friendFriends + 1,
    });
  }
