TypeError on response code 204 - no data

[apstanisic]

Is the error occurring when you update/create your collection or when you update/create role?
Are you providing converter?

I this the problem is here:

 /// directus_response.dart
 /// Constructor that converts [Dio] [Response] to [DirectusResponse].
  DirectusResponse(Response dioResponse, {ItemsConverter? converter}) {
    converter ??= MapItemsConverter();
    var data = dioResponse.data['data'];

    if (data is List) {
      throw DirectusError(message: 'List should use DirectusListResponse.');
    } else if (data is Map<String, Object?>) {
      this.data = converter.fromJson(data);
    } else {
      this.data = data;
    }
  }

If data is not Map or List it simply returns received, but that data does not fit return type, so it throws an error.
Maybe we should set this.data = {"response": data } in else, so it does not return an error, but that might confuse users who expect that returned Map is created item. We can
But I don't know if this should be changed in Dart SDK or in Directus, cause their API reference says that it returns created object. Maybe API should return empty object if no field is allowed to be read?

Can you try this branch? I don't have time today to test it, this is maybe dirty fix. https://github.com/apstanisic/directus-dart/tree/fix-no-data
It simply allows returning nullable values for create/update endpoints.
You can add package directly from GitHub https://stackoverflow.com/questions/54022704/how-to-add-a-package-from-github-in-flutter

With your branch unfortunately the build fails because of a nullable error.

: Error: A value of type 'Future<DirectusResponse<DirectusSettings?>>' can't be returned from a function with return type 'Future<DirectusResponse<DirectusSettings>>' because 'DirectusSettings?' is nullable and 'DirectusSettings' isn't.
../…/settings/settings_handler.dart:24
 - 'Future' is from 'dart:async'.
- 'DirectusResponse' is from 'package:directus/src/data_classes/directus_response.dart' ('../../Tools/flutter/.pub-cache/git/directus-dart-bb639c48a0b71008e0299b63c834a874b9ee5aab/lib/src/data_classes/directus_response.dart').
package:directus/…/data_classes/directus_response.dart:1
- 'DirectusSettings' is from 'package:directus/src/modules/settings/directus_settings.dart' ('../../Tools/flutter/.pub-cache/git/directus-dart-bb639c48a0b71008e0299b63c834a874b9ee5aab/lib/src/modules/settings/directus_settings.dart').
package:directus/…/settings/directus_settings.dart:1
      items.updateOne(data: data, id: '1');

Sadly I currently have no time to look into it myself.
Directus-wise I think it makes sense to return nothing if you dont't even have the permissions to access the item.
Like with readMany you dont get an array of empty objects but an empty array.

Can you check 0.9.1, it should fix it. Reopen if error still exists.
