Panic stacktrace is not detailed on some platforms

Report

On Windows and Android, there are not enough frames showing up in the stacktrace. Most of the frames are missing because they cannot be resolved.

On macOS and iOS, the code filenames are not visible because frames in that Rust code don't include the filename information. It would be great to enable filepath information.

Things that don't make any difference:

• Using the default panic hook of Rust without set_hook
• RUST_BACKTRACE=1 /RUST_BACKTRACE=full environment variables

Windows, Android:

macOS, iOS:

Ubuntu:

web: Not handled by Rinf. Handled by wasm_bindgen.

This is the panic handler code. We replace the native panic hook with the std::panic::set_hook function, sending the panic info to Flutter to print it in the CLI(Only in debug mode, of course) with our debug_print! macro.

On Android, if you disable the resolve step by commenting it out, many more unnamed frames appear in the stacktrace, which seem to derive from our Rust code.

This issue can be related to cargokit or missing .pdb files after compilation, but we do need deeper anaylsis.

Steps to Reproduce

Just use panic! anywhere in the Rust code.

System Information

I'm testing on multiple platforms, but they all pass these checks.

rustc --version
protoc --version
flutter doctor

Also, it will be good to print panics to the CLI on the web, too.
