How to bundle native macos executable with a flutter app? - flutter

Question

I want to bundle a native console program for macos written in Rust, into a Flutter app.
The Flutter app needs to call this program from Dart with something like this:
Process.runSync("./myconsoleapp", ["argument1", "argument2"]);
The Flutter app can't seem to find myconsoleapp.
Is there a way to embed myconsoleapp into the Flutter app, and make it executable? I tried manually adding and it didn't work.

Answer 1

Flutter for windows simply bundle project.exe along with a bunch of other files into a directory in (build\windows\runner\debug\). No one can stops you from adding your files to that directory.
In your dart code, simply start a new process from the newly added file:
var exePath =
p.join(p.dirname(Platform.resolvedExecutable), 'myFile.exe');
var result = await Process.run(exePath);

Answer 2

It can't find your executable because there is no relationship between ./--which is the current directory in the environment your app was launched from--and your application's location. If you want to access something bundled in your application you should be using NSBundle's pathForResource:ofType: to get the path to it (either via a method channel, or FFI).
Is there a way to embed myconsoleapp into the Flutter app,
You would add it as a bundled resource via Xcode. (There's nothing Flutter-specific about this step.)
and make it executable?
Presumably the product of your Rust build process is already executable.
