Hi,

Included example app crashes on iOS:

Unable to reproduce on iPhoneX with flutter beta. Assuming you're trying to debug example app as-is to device?

[soyangel]

I'm just compiling from example dir with:

flutter build its

and then Archive - Product - export as Ad hoc from Xcode. Same as with my other Flutter apps that work (e.g. the real app I'm using this library on that it's working ok with a version previous to FFI).

Maybe I have to set some option on Xcode so it links the .a?

Running on iPhone 7 with iOS: 13.4.1
Xcode: 11.4.1

Yes, so debug mode seems to work just fine. Release mode not so much, I'm running into a white screen without any error logging whatsoever. Investigating.

Possibly related: dart-lang/native#897

[kozw]

I've just pushed an update that might fix the function lookup failure in release mode. Does this work for you?

[soyangel]

It works great here.

Thanks for your work!
