Updates user data, if there is a logged in user.

```dart
final res = await supabase.auth.update(
  UserAttributes(data: {'hello': 'world'})
);

final error = res.error;
```

## Notes

It's generally better to store user data in a table inside your public schema (i.e. `public.users`).
Use the `update()` method if you have data which rarely changes or is specific only to the logged in user.

## Examples

### Update a user's metadata.

```dart
final res = await supabase.auth.update(
  UserAttributes(data: {'hello': 'world'})
);

final error = res.error;
```
