Unhelpful error messages in Custom Functions section

[stefanlenoach]

Has your issue been reported?

• I have searched the existing issues and confirm it has not been reported.
• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

I'm trying to write a custom function that turns a LatLng into a city name. When I try to run my function in the custom function section I get an incomprehensible error that just says "Error in - distance". I don't use the word distance at all in the function

Expected Behavior

More useful/debug-able error messages in the custom functions section.

Steps To Reproduce

1. Create a new custom function.
2. Make the input a LatLng named latlng and the return type a string
3. Add these imports:
   import 'dart:async'; import 'package:geocoder/geocoder.dart'; import 'package:geolocator/geolocator.dart';
4. Paste this code into the function:

  final addresses = await Geocoder.local.findAddressesFromCoordinates(coordinates);

  if (addresses.isNotEmpty) {
    final first = addresses.first;
    return first.locality;
  }

  return null;

Try saving the code.

Context

I just want a working custom function that turns the LatLng into a city name. But at a higher level it seems the error messages given for the custom functions section is very lacking.

Hi @stefanlenoach. Sorry for the slow response.

I can't reproduce the issue - when I follow the steps it saves it fine. Can you add a screenshot or a video?

However, I see a couple of issues with your function:

• You can't add imports to custom functions - all custom code has to go between MODIFY CODE ONLY BELOW THIS LINE and MODIFY CODE ONLY ABOVE THIS LINE.
• You can't use await in custom functions, they have to be synchronous.

BTW you can do all of the above in custom actions.
