To get user references from authenticated users in FlutterFlow and link that data to text boxes, you can follow these steps. Assuming you're using Firebase for authentication and Firestore for your database, here’s a detailed approach:

Step 1: Set Up Firebase Authentication and Firestore

1. Firebase Authentication: Make sure you have Firebase Authentication set up in your FlutterFlow project. This allows you to authenticate users and get their unique user IDs (UIDs).

2. Firestore Database: Ensure you have a Firestore database set up. You will store user-specific data in this database.

### Step 2: Add User Data to Firestore

When a user registers or logs in, you should create or update a document in Firestore with their UID. Here’s an example of how to structure your user documents:

```json

{

\"users\": {

\"UID12345\": {

\"name\": \"John Doe\",

\"email\": \"john.doe@example.com\",

// Add other user-specific fields here

}

```

### Step 3: Fetch User Data in FlutterFlow

1. Query Firestore: In FlutterFlow, you can query Firestore to fetch the user data based on the authenticated user’s UID. Here’s how you can do it:

- Go to the Firestore Database section in FlutterFlow.

- Create a new collection query for the users collection.

- Use a filter to get the document where the document ID is equal to the authenticated user’s UID.

2. Set Up Variables: Create variables to hold the user data you fetched from Firestore.

Step 4: Link Data to Text Boxes

1. Add Text Boxes: Add text boxes (or any other widgets) to your screen where you want to display user-specific data.

2. Bind Data: Bind the text boxes to the variables holding the user data. This ensures that the text boxes display the correct data fetched from Firestore.

Detailed Steps in FlutterFlow:

1. Create a Firestore Query:

- Go to Firestore Database in FlutterFlow.

- Create a new query for the users collection.

- Set the query filter to match the authenticated user’s UID.

- Use the Document ID field and set it to the current user’s UID. You can access the authenticated user’s UID using authUser.uid.

2. Create Variables to Store User Data:

- Go to Variables in FlutterFlow.

- Create new variables to store user data (e.g., userName, userEmail).

3. Bind Query Results to Variables:

- In the query result settings, map the Firestore document fields to your FlutterFlow variables.

4. Bind Variables to Widgets:

- For each text box (or other widget) where you want to display user data, bind the widget’s value to the corresponding variable.

### Example:

If you have a text box for the user’s name:

1. Add a text box to your screen.

2. Bind the text box’s value to the userName variable you created earlier.

3. Make sure the query runs when the screen loads or when needed to ensure the latest data is fetched and displayed.

Sample Firestore Query in FlutterFlow:

- Collection: users

- Filter: Document ID is equal to authUser.uid

- Result Mapping: Map Firestore fields to FlutterFlow variables (e.g., name to userName, email to userEmail).

By following these steps, you can easily link authenticated user data from Firestore to text boxes or other widgets in your FlutterFlow app. This makes it straightforward to display personalized data for each user. If you have specific issues or need further details on any step, feel free to ask!
