Librealm_dart.dylib: No such file or directory

MongoDB Atlas App Services & Realm Realm

I have installed Realm on macOS and plan to develop a Flutter app that will sync with Atlas. To get started, I copied the standard basic example in Dart. The code compiles without issues, but when running it, it complains about a missing library:
librealm_dart.dylib.

I have searched the web for a week, reinstalled everything, including Xcode, but the problem persists. I would greatly appreciate any feedback, as I am stuck and have exhausted all the options I knew.

I found the cause of the issue. The name of one of the directories in the path includes a space. Apparently that causes an issue…

HI @Omid_Ejtemai! Welcome to the MongoDB community!
I am glad you were able to figure it out.
Yes, it looks like it isn’t treating the entire path as a single argument to the touch command (it should be in quotes), so it tries to run the touch command with the path starting at code/my_first_db_app/... .

Good luck playing around with the realm Flutter SDK!

FYI - I reached out to the Flutter SDK team and they will investigate fixing this for an upcoming release.

Thank you for bringing this to our attention!
