0.5.4 Exception after upload to Google Play

[mrcsh]

The Android version of my application is throwing the following exception after updating to 0.5.4
(ios seems to be unaffected)

Unsupported operation: package:webcrypto cannot be used from scripts or `flutter test` unless `flutter pub run webcrypto:setup` has been run for the current root project.

The error does not happen in debug mode on the simulator nor when running in release mode.
My guess is the upload process is stripping some symbols that is causing the failure?

Reverting to 0.5.3 resolved the issue for now.

Comes from here:

webcrypto.dart/lib/src/boringssl/lookup/lookup.dart

Line 34 in 5e6d20f

library = DynamicLibrary.open('libwebcrypto.so');

Either:

• DynamicLibrary.open fails because libwebcrypto.so isn't found, or,
• Symbols are stripped so that when it looks for them it throws an ArgumentError.

It's been a while since I tested how this code works. Never tried releasing it.

To be clear, I won't dive into this anytime soon. I don't have time and can't reproduce.

If you can reproduce please consider bisecting the git history between the two releases: 0.5.3...0.5.4

Or test what happens before/after: c0c3a1b maybe LTO had some impact.

You can just use a git dependency on this repository to test out a few different versions (might require you to do a dependency_override too).

Hi, this is biting our android build as well. I'm getting the same "unsupported operation" exception in my console using v0.5.4 when we run Hash.sha1.digestBytes() (likely other webcrypto operations as well but that's the one I noticed).

It is reproducible every time for me, so easy enough to track down. I did a git bisect using dependency overrides in my project's pubspec, and the LTO commit you mentioned, c0c3a1b, is the culprit. The previous commit, 29aad7a, is fine.

As mentioned, 0.5.3 is working well, so we'll stick with that until this can be fixed. Thanks.

Edit: I forgot to mention that this exception is happening for me in debug mode as well as the simulator, which is different than @mrcsh's scenario.

Filed a PR to disable LTO on Android.

That'll probably adversely affect the binary size. But, hehe, if it was removing all symbols that might be acceptable.
