FFI will not run in release mode unless the Testability flag is set (IOS)

[EPADDO]

Hello,
I have some C which I have used the FFI interface to reference C functions. It works perfectly in debug mode on IOS14 device and it also works perfectly on the release mode but only if I enable the testability flag. No matter what else is tried inclusive of changing the strip style to non global, the method cannot be found for the C routine. In addition, it is not C++ code so I cant specify the attribute flag.
It seems that the symbols are stripped out that references the method. Is there any other work around for this?
Tried calling: call(Pointer: address=0x122f0e160, 32, Pointer: address=0x282a955c0)
#0 Object.noSuchMethod (dart:core-patch/object_patch.dart:38)
dart-archive/ffi#1 _objectNoSuchMethod (dart:core-patch/object_patch.dart:85)
dart-archive/ffi#2 speex_enc_dec.encodeAudio (package:rapid_app/speex_enc_dec.dart:166)
dart-archive/ffi#3 onStart. (package:rapid_app/main.dart:430)
dart-archive/ffi#4 _RootZone.runUnaryGuarded (dart:async/zone.dart:1593)

Regards David.

Did you use flutter create --template=plugin_ffi --platform=ios?

Trying to use FFI from scratch often has issues with bundling (see the existing iOS issues on the Flutter repository). That is why we have created that template. Please use that template.

Thank-you. I shall try that method and revert back.

Hello, that has fixed the issue. I do have one question though, these flags were not honoured and I needed to set some of the defines manually in the c code s.compiler_flags
the -D flags are not used when the plugin compiles.
