Same error here with Flutter 1.20.2.

It works after downgrading to Flutter 1.17.5.

rohansingh commented 3 years ago

Same issue with Flutter 1.20.2. I won't pretend to understand the underlying issue, but I was able to workaround it by reverting to a pre-FFI revision (0575e585b3c6ed421e218eded97f461e12a370c4).

soyangel commented 3 years ago

Does the workaround mentioned on https://github.com/flutter/flutter/issues/62853 works with this plugin?

I'm trying with a modified pubspec.yaml including with the "platforms:" section but get the same error.

kozw commented 3 years ago

That issue is definitely related. However the problem is not pubspec.yaml, but the podspec which has changed significantly since Flutter 1.20. Still looking for a solution though.

vishnukvmd commented 3 years ago

Downgrading Flutter to 1.19.0-4.3.pre solved this for me (I had to say goodbye to a few nice things, but better them than libsodium).

@kozw What is weird is that the example app you've been kind enough to provide works well with Flutter 1.20.4 (stable). But my application freezes with (dlsym(RTLD_DEFAULT, sodium_init): symbol not found). Copying the missing elements from the example's Podfile, did not help.

kozw commented 3 years ago

You most likely get a warning that the Podfile is out of date. When you remove the podfile in example/ios folder, it will be regenerated with something different in flutter 1.20 and you'll get the same error.

It's still a mystery to me would I need to do to fix this.

kozw commented 3 years ago

Scratch that previous comment. Just had a brainwave and flutter_sodium now seems to work with flutter 1.20.

Please try 0.1.5 available in pub.dev.

rohansingh commented 3 years ago

Hmm, 0.1.5 fails to build on Android:

My bad, fixed in 0.1.6. All should be good now.

rohansingh commented 3 years ago

Just confirming, 0.1.6 works beautifully. Thanks so much!

kozw commented 3 years ago

Good to hear, enjoy!

nailkhasipov commented 3 years ago

Also confirmed that 0.1.6 works perfectly with Flutter 1.22.0 beta. Thanks! 🎉
