Failed to load dynamic library 'JavaScriptCore.framework/JavaScriptCore'
Versions: platform: macOS release (crash report collected from user), some devices.
Error:
Failed to load dynamic library 'JavaScriptCore.framework/JavaScriptCore': dlopen(JavaScriptCore.framework/JavaScriptCore, 1): no suitable image found. Did find:
file system relative paths not allowed in hardened programs

Others: According to this blog
The file path misses the / on the front and thus is a relative path. But that is forbidden for library loading for applications using hardened runtime, which is more strict for improved security.
I also encountered this problem. It seems that this library is no longer maintained? It's been over a year and still hasn't been closed.
The chaldea-center/flutter_js folk changed DynamicLibrary loading:
- ? DynamicLibrary.open('JavaScriptCore.framework/JavaScriptCore')
+ // or use:
+ // DynamicLibrary.open('/System/Library/Frameworks/JavaScriptCore.framework/JavaScriptCore')
+ ? DynamicLibrary.process()
In iOS/macOS, DynamicLibrary.process() should include all global symbols which should contains JavaScriptCore, also you can specify the absolute path /System/Library/Frameworks/JavaScriptCore.framework/JavaScriptCore.
Tested on macOS 14.2.1 and iOS 17.3.1, the above two open methods are both working.
If any other iOS/macOS/simulator version didn't support these two methods or have to specific absolute path, you can share your system version and solution here to help others.

I will change it and I will submit a patch version with the change
