I'm trying to firestore documents through react native app, but facing the following issue

Here is the code

constructor() {

    super();

    this.ref = firebase.firestore().collection('todos');

  }

and we are triggering button click

addTodo() {

      this.ref.add({

        title: this.state.textInput,

        complete: false,

      });

    }

we are facing this issue

Error: Firestore: The caller does not have permission to execute the specified operation. (firestore/permission-denied).
Error: Firestore: The caller does not have permission to execute the specified operation. (firestore/permission-denied).

If this error occurs when you run addTodo() it means that the user doesn't have permission to write to the todos collection. Access to Firestore data is controlled through its server-side security rules.

To simply allow anyone to write to todos use a rule such as this:

service cloud.firestore {

  match /databases/{database}/documents {

    match /todos/{document=**} {

      allow read, write: if true;

    }

  }

}

But I highly recommend you read the documentation so that you can write more secure rules that match the needs of your app.
