I used Carousel_Slider package in my flutter app and faced an issue?

I used Carousel_Slider package to build an image slider for my flutter app and I copied the parts of the code that I needed .SO after runnig the app I faced an issue that says ...
: Error: The value 'null' can't be assigned to a variable of type 'List' because 'List' is not nullable.
carousel_slider.dart:59
'List' is from 'dart:core'.
'Widget' is from 'package:flutter/src/widgets/framework.dart' ('../../Documents/flutter/packages/flutter/lib/src/widgets/framework.dart').
framework.dart:1
: items = null,

based on error logs ,
the List that you are giving in CarouselSlider Widget is null,
print your list in build to check what is the value of List that used in CarouselSlider.

Why can't my flutter tests run on Codemagic?

I have written three simple integration tests that are located in a test directory. I run work on Windows and I use an Android emulator. They always fail on Codemagic (macOS Standard VM, 2.3GHz Quad Core / 8GB). I don't know why but it uses this flag to run the tests:
flutter test --machine
And even with the
--machine flag the tests run perfectly on my machine.
Now here are the logs when running on my machine:

from the log your error is this one (you can find it in Codemagic UI too)
MissingPluginException(No implementation found for method getApplicationDocumentsDirectory on channel plugins.flutter.io/path_provider_macos)
Seems you need to fix your unit tests that using path_provider package since they can't be run on macOS. Maybe this link https://pub.dev/packages/path_provider#testing will be helpful

Why does this not work with flutter?

After reading https://github.com/dart-lang/sdk/issues/29543#issuecomment-298888237 I think you might want to try adding a pubspec dependency on convert: "^2.0.1". Does that help?
