No preview window on Windows 10, Flutter 3.24, Monarch 2.2.7

[kylenoteboom]

I run execute monarch init and monarch run in a fresh project (simple template from the flutter CLI that creates a new project :

flutter create monarch_test
cd monarch_test
monarch init
monarch run

Monarch does start and prepare and attach to stories, but no preview window pops up with the Monarch UI. Selecting a different story or preview device doesn't make the preview window appear either.

Monarch --version output:

Monarch version 2.2.7

Monarch modules:
- cli: 3.0.5
- controller: 1.4.2
- platform_app: 2.3.1
- preview_api: 2.4.1

flutter --version output:

flutter --version

An initial look at the verbose logs indicated MSBuild missing, but installing that explicitly and additing its bin directory to the PATH didn't appear to change this behaviour.

I wasn't able to make much of the verbose logs yet, but please do find them attached:

log_monarch_cli.log

Aside: a preview version (likely Flutter 3.19) worked fine on the exact same Windows installation, but I've not (yet) invested the time to try and get that working again.

As I mentioned, Flutter 3.19 does work. This required downgrading environment.sdk to ^3.3.0 and the monarch package to ^3.0.0 in pubspec.yaml. Additionally, I had to use monarch_cli (not sure that's the correct name, but it's the executable in the binary release the guide on the website directs users to download) to version 2.2.3.

log_monarch_cli.log

No comparison of the logs on my end yet, though.

I'll run it soon to see what's going on. Thank you for the report.

Fixed. I had to upgrade the dart sdk on the windows build machine. Monarch on Windows should work with Flutter 3.24.2.
