  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.auth != null;
    }
  }
}

to

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if true;
    }
  }
}

but i have the same error.

Answer 1

Inside projectFolder/android/app/src/main/AndroidManifest.xml add the following:

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Answer 2

According to this post , there is an error with your app accessing the internet. Please check your network connection:

Check that you have the proper internet permissions in the androidManifest file (suggested by Abhishek Dutt).

If you are using an emulator, check if the emulator can access the internet using this post.

Answer 3

After several I realized that the problem was not only under MacOs but with emulators. And by digging further I realized that it is AppCheck that I activated on the project which does not accept all the requests of the Debug mode under the emulator.

Answer 4

As mentioned in the docs https://firebase.google.com/docs/app-check/flutter/debug-provider

  await FirebaseAppCheck.instance.activate(
    // Set androidProvider to `AndroidProvider.debug`
    androidProvider: AndroidProvider.debug,   );

Your app will print a local debug token to the debug output when Firebase tries to send a request to the backend. For example:

D DebugAppCheckProvider: Enter this debug secret into the allow list in
the Firebase Console for your project: 123a4567-b89c-12d3-e456-789012345678

enter image description here

In the App Check section of the Firebase console, choose Manage debug tokens from your app's overflow menu. Then, register the debug token you logged in the previous step.

Firebase console

After you register the token, Firebase backend services will accept it as valid.
