Flutter’s latest 3.10 update introduced an unexpected hurdle when deploying my project to a Windows server. Specifically, I encountered a persistent “404 (Not Found)” error related to the “assets/AssetManifest.smcbin” file. As a result, none of the asset images were displaying on the website.
After some investigation, I discovered a solution to this problem. It turns out that adding the appropriate MIME type for the “.smcbin” file extension is crucial. Specifically, I needed to set the MIME type as “application/octet-stream” for the file. Additionally, it’s important to restart the server’s pool and refresh the browser to ensure the changes take effect. If the issue persists, trying to access the website in an incognito or private browsing mode could help resolve any caching-related problems.
By following these steps, I was able to overcome the asset loading issue and ensure that the asset images were correctly displayed on my Flutter web project deployed on a Windows server.
