Symbolicate Flutter crash

Question

While running my app in Android Studio, it crashes with:

F/libc    (28855): Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0 in tid 28898 (1.ui), pid 28855 (nalquest.survey)

I'm also able to reproduce this when debugging the Android project in Android Studio, but I get an opaque stack trace, there, too.

Here are details of my Flutter environment:

[✓] Flutter (Channel stable, 3.13.2, on macOS 13.4.1 22F770820d darwin-arm64, locale en-US)
    • Flutter version 3.13.2 on channel stable at /Users/csabbey/homebrew/Caskroom/flutter/3.3.6/flutter
    • Upstream repository https://github.com/flutter/flutter.git
    • Framework revision ff5b5b5fa6 (3 weeks ago), 2023-08-24 08:12:28 -0500
    • Engine revision b20183e040
    • Dart version 3.1.0
    • DevTools version 2.25.0

I came across flutter symbolize, but to use that, it looks like I'd have to run an obfuscated version of my project, where I generate the debug info for it to use, but I would imagine the unobfuscated version would be symbolicatable.

How can I find the cause of this 'null pointer dereference'?
