在过去的几天里，我一直在尝试让AppCheck在Flutter中正常工作，同时使用AndroidProvider.playIntegrity，但我一直得到权限错误。由于AppCheck Firestore已经设置为enforced，当我使用AndroidProvider.debug时（插入调试令牌后），一切都很好。当我停止使用调试时，这就是问题所在。
错误信息

W/Firestore( 5050): (24.4.1) [Firestore]: Listen for Query(target=Query(users/abc123/foo order by __name__);limitType=LIMIT_TO_FIRST) failed: Status{code=PERMISSION_DENIED, description=Missing or insufficient permissions., cause=null}

• • 主省道**

WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();

// Trying to use AndroidProvider.playIntegrity
await FirebaseAppCheck.instance.activate();

// Works fine in debug
// await FirebaseAppCheck.instance.activate(
//   androidProvider: AndroidProvider.debug
// );

• • Firestore规则**（用于开发目的）

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
  
    function isAuth() {
      return request.auth != null;
    }
    
    function isDev() {
      return isAuth() && request.auth.token.email in [
        'testemail@gmail.com'
      ];
    }

    match /{document=**} {
      allow read, write: if isDev();
    }
  }
}

我想可能是缺少了一些依赖项，所以我尝试在我的build. gradle文件中添加

dependencies {
    ...

    // Tried enabling this but nothing really happened so I commented it out
    // implementation 'com.google.firebase:firebase-appcheck-playintegrity'

    ...
}

因为它被添加到Android指令中，但最终注解掉了，因为它什么也没做。
然后，也许它需要是一个实际的版本，所以我创建了一个阿尔法版本在播放控制台，并获得批准后，我下载了应用程序，似乎我仍然不能连接到Firestore。
项目设置和AppCheck PlayIntegrity中的SHA-256指纹取自调试证书、应用签名密钥（Play控制台）和上传密钥（Play控制台）。

• • 顺便说一句，**我将compileSdkVersion设置为33，将targetSdkVersion设置为31。它们应该相同吗？
