Hi, is there a way to use the Android Studio debugger when using Dart FFI in a Flutter app?

Hi Facundo,

I'm not familiar with setting up the Android Studio Debugger.

These are the two things I do:

- use the Dart debugger for Dart code

- use GDB (or the VSCode C++ plugin with GDB integration) on the dart executable for debugging C++ code (in which the Dart stack frames show up as unknown code).

What exactly are you trying to debug? C++ code? Dart code? Or the FFI bindings (e.g. do you get segmentation faults on the de boundary)?

And can you test your code in Dart standalone? (that makes debugging native code easier, since you don't have to deal with Android simulators etc.)

Kind regards,

Hello Daco,

First of all, thanks for answering so quickly. To be more specific, I'm trying to do a Flutter app, wich uses a C++ backend for signal processing. To achieve that, I'm passing my C++ backend pointers with the data to process, and I'd like to be able to debug that backend, look into local variables and do more than just debug with log messages.

I'm familiar with the VS Code debugger and the Android Studio debugger, but in both, when running the Flutter app I can only debug the Dart front end, and not get into the C++ implementation.

Thanks for any help you can provide.

Regards,

Facundo Farall
