Issues with adding today extension to flutter app

Question

I wrote an app in Flutter, and I am looking to add a native iOS today extension to it. I added the widget target but when I try to build the build fails because the app extension target can not find specific flutter libraries (which does not make sense since it wouldn't use them anyway).

From what I can gather, the xCode project is trying to include Flutter libraries with all targets?

Here is the error:

ld: warning: directory not found for option '-F/Users/nickmowen/Library/Developer/Xcode/DerivedData/Runner-egikkgpuyfdkbcconodjborapzme/Build/Products/Debug-iphoneos/share'
ld: warning: directory not found for option '-F/Users/nickmowen/Library/Developer/Xcode/DerivedData/Runner-egikkgpuyfdkbcconodjborapzme/Build/Products/Debug-iphoneos/shared_preferences'

ld: framework not found FMDB
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any ideas to fix this? Thanks!

Edit:

Going into Pods and enabling bitcode for each of the flutter libraries in there got rid of a bunch of errors, but then I am getting this error:

ld: '/Users/nickmowen/Library/Android/flutter/bin/cache/artifacts/engine/ios/Flutter.framework/Flutter' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file '/Users/nickmowen/Library/Android/flutter/bin/cache/artifacts/engine/ios/Flutter.framework/Flutter' for architecture arm64

do you use them on your code , because these are not exist on the sandbox by default — mohsen, Mar 18 '19 at 05:27
I use them in the flutter code but not in the today extension. I updated with new info — Nick Mowen, Mar 18 '19 at 05:28
According to Flutter SDK, it doesn't support bit code. You shouldn't enable it. — Sachin Vas, Mar 18 '19 at 05:32
@SachinVas So does that mean I can't use a today extension (which I believe requires bitcode?) — Nick Mowen, Mar 18 '19 at 05:33
I guess you should make them on sandbox before you want to use it — mohsen, Mar 18 '19 at 05:38

This works for me.

Project -> Building Settings -> Enable Bitcode Set to 'NO'

Added new build setting for Enable Bitcode and set to No, and now it works. Thanks. – david72 Aug 01 '19 at 19:29

After fresh added Today Extension, no need to enable bitcode, just overwrite setting in Target: Today Extension:

LIBRARY_SEARCH_PATHS = "";

OTHER_LDFLAGS = ""; or OTHER_LDFLAGS = "-ObjC";

Maybe need clear DerivedData
