About crate-type = ["staticlib"]

It would be nice if flutter_rust_bridge added the option to have rust only generate static libraries (using the ffi.DynamicLibrary.executable load symbol within flutter).

Hi, firstly, may I know why do you need that?

In addition, flutter_rust_bridge does not restrict any ways of building/linking. Thus, it is possible to tweak the underlying cargokit for your need.

On desktop OS, it is sometimes necessary to protect cryptographic algorithms using VMProtect. In case of using dynamic link libraries, symbols are always exposed. Using VMProtect after linking a static library to the main program is a bit safer（Even if the parameters of the symbols are figured out, you can't simply take the dynamic library and use it directly）.

I see. Feel free to ask questions if the proposed methods above does not work!
