Appwrite Cloud Functions listDocuments

Hi guys -

I struggle with the cloud functions - I need to get Documents from 2 collections and then send it to the client. But I cannot find any documentation about listDocuments or something. I already tried graphql, but there I always get an error

I think there is just a small Syntax, but I tried long time and I also cannot find anything helpful...

I use appwrite CLI to deploy the function.

this is the error:

TypeScript

[response], {errors: [{message: Syntax Error: Expected :, found Name "collectionId", extensions: {category: graphql}, locations: [{line: 4, column: 11}]}]}
```

this is the code:
```
import 'dart:async';
import 'package:http/http.dart' as http;
import 'package:dart_appwrite/dart_appwrite.dart';

Future<dynamic> main(final context) async {
  final client = Client()
      .setEndpoint(endpoint)
      .setProject(String.fromEnvironment(projectId))
      .setKey(String.fromEnvironment(SecretKey));

  final graphQL = Graphql(client);

  final response = await graphQL.query(
    query: {
      'query': ''' query GetHubsAndPosts {
        databasesListDocuments(
          databaseId: $db_id,
          collectionId: $collectionId
        ) {
          total
          documents {
            _id
            data
          }
        }
      }
    '''
    },
  );

  context.log('[response], $response');

  return response;
}

```

TL;DR

The developer is having trouble with a cloud function in their app and is looking for assistance. They are trying to get documents from two collections but are encountering errors. They have already tried using GraphQL but encountered a syntax error. The developer is using the Appwrite CLI to deploy the function. Solution: The developer is advised to use the Appwrite Dart SDK instead of GraphQL. They are provided with the relevant documentation for using the SDK.

Do you need to use GraphQL? Or you'd be willing to use the dart sdk? Also, I don't see an import for the dart graphql package in your snippet. If you're willing to use the sdk here's the relevant documentation https://appwrite.io/docs/references/cloud/server-dart/databases
