I really don't know what the problem is. But since I want to take data from my Cloud Firestore and want to display it in the app, it doesn't work. I get the error message:

W/Firestore( 8928): (24.4.1) [WatchStream]: (aab9534) Stream closed with status: Status{code=PERMISSION_DENIED, description=Cloud Firestore API has not been used in project 416187152002 before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/firestore.googleapis.com/overview?project=416187152002 then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry., cause=null}.

Rules:

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

The data I want to query

I would like the message to go away and the problem resolved.

There are 3 possible points of failure in my opinion and those are with solutions:

1. Check whether your firestore database API is enabled for this follow:
   • Goto firestore and select your project
   • click on Firestore database from the build dropdown situated at the left side
   • If you are able to see your database then consider your API is enabled if not you will see the create database button hit create with your required options then it will be automatically enabled.
2. If you have enabled the API earlier and are still seeing this error check that your service account has the necessary permissions to access the firestore db this can be verified by:
   • Goto cloud console IAM and click on view by roles
   • Check whether Firebase Admin SDK Administrator Service Agent has a service account which is something like firebase-adminsdk-@<project_id>.iam.gserviceaccount.com and has exact project id as your firebase project id.
3. Check on the App Engine Settings page to ensure it's not disabled for your project as it's required to run firestore db.

Also consider adding one document manually to the db then try after some time

If all these didn't work consider contacting firebase support

My mistake was that I used an outdated google-services.json file. This bug has been keeping me busy 10 hours a day for two days now without finding a solution. I tried all of them, but nothing worked. If you re-paste google-services.json it probably still won't work because you have to run flutter clear afterwards and then flutter get packages. I hope I could help you
