cc again @johnmccutchan @jason-simmons @jonahwilliams, because you all had input on the original pr to get debug symbols included in app bundles a year ago (this is the last piece, if it lands)


// AGP handles stripping debug symbols from native libraries, so we default
// to not stripping on Android.
extraGenSnapshotOptions.add('--no-strip');

I don't think this is the right change to make. stripping dart shouldn't be related to stripping the native code

Hmm, I agree they are two different tasks. But do you think these symbols are not useful to app stores?

not sure I understand, libapp.so isn't really a native library. You should leave this as is.

Summarizing offline discussion with @jonahwilliams - libapp.so isn't a true native library, and app stores would therefore not be able to make use of libapp.so.sym. By default the dart stack traces are not obfuscated (so the symbols are useless).

There is an opt in feature that developers can use (--split-debug-info) which removes this information from libapp.so. But even in this case, the app store wouldn't be able to understand the produced symbol file, because libapp.so is not a true native library. So the file would be useless in either case.

A small piece of #162464 that I
wanted to land anyways.

Looks like getting this into a working state by resolving conflicts in the ui was optimistic, will get this out of draft when the tools tests are passing

Relands #162464
Fixes #170664

The only test that failed last time was `Linux_pixel_7pro
android_obfuscate_test`, and I ran it locally (`flutter test
test/integration.shard/android_obfuscate_test.dart `) to both repro the
failure and verify it passes on this branch with the additional changes.

Also does some stuff in the FGP:

The reason we failed the tests last time was we were bundling of the
libapp.so code into a jar in the aar case, instead of simply including
it as its own file in the source sets. I let gemini go on that part,
modifying it to no longer pack as a jar, but it looks correct to me. Now
that the `libapp.so` file is simply included in this case, AGP is able
to strip it (it's not hidden inside a jar).

Because this changes the FGP build process for add to app, I manually
verified that the add to app flow isn't broken for including a flutter
module both as source and as an aar.

flutter-zl pushed a commit to flutter-zl/flutter that referenced this pull request Feb 10, 2026
…lutter#181275)

Relands flutter#162464
Fixes flutter#170664

The only test that failed last time was `Linux_pixel_7pro
android_obfuscate_test`, and I ran it locally (`flutter test
test/integration.shard/android_obfuscate_test.dart `) to both repro the
failure and verify it passes on this branch with the additional changes.

Also does some stuff in the FGP:

The reason we failed the tests last time was we were bundling of the
libapp.so code into a jar in the aar case, instead of simply including
it as its own file in the source sets. I let gemini go on that part,
modifying it to no longer pack as a jar, but it looks correct to me. Now
that the `libapp.so` file is simply included in this case, AGP is able
to strip it (it's not hidden inside a jar).

Because this changes the FGP build process for add to app, I manually
verified that the add to app flow isn't broken for including a flutter
module both as source and as an aar.
