Failed to load dynamic library 'rive_native.dll' in test

[Zigotote]

Description

I upgraded Rive to 0.14.0-dev.10 to display a RiveWidgetBuilder. The app works but my tests are broken with the message Failed to load dynamic library 'rive_native.dll'.

I used rive 0.13.1 because of another problem in tests, described in this issue : #354.

Steps To Reproduce

Steps to reproduce the behavior:

1. Create an app with a RiveWidgetBuilder
2. Create a simple test file with

testWidgets("should display page", (tester) async {
    await tester.pumpWidget(MyRiveWidget());
    await tester.pumpAndSettle();
});

3. Run the test and you should see the message

The following ArgumentError was thrown building MyRiveWidget:
Invalid argument(s): Failed to load dynamic library 'rive_native.dll': error code 126

Source .riv/.rev file

Reproduced with this file : https://rive.app/marketplace/2997-6322-darklight-switch/
But I suppose it can be reproduced with any rive file

Expected behavior

The tests should run

Before running flutter test, can you first run:
dart run rive_native:setup --verbose --clean --platform windows

That will download the native libs. We automatically run this when doing flutter run as part of the Windows Makefile, but we can't (unless there is a way we don't know) do that automatically for flutter test.

I tried but it doesn't fix the tests, I have the same error message with error code 126
