C++ doesn't have a stable ABI (for example, it varies by compiler), so we can't directly interop with it. However, it would be possible to parse a C++ API, code-gen C compatible bindings for the API (using `extern "C"`), then generate Dart bindings that look like the C++ API, but actually invoke the C glue code.
The goal of this project is to add C++ as a new experimental language in FFIgen. FFIgen already uses libclang to parse C/ObjC APIs, so the parsing logic just needs to be extended to parse C++ APIs. Then the AST needs to be extended to be able to represent C++ language features. Finally, the code generator needs to be extended to support generating C code to wrap the C++ API, and Dart code to interact with the C API.

A good proposal for this project will explore the various language features of C++, describe how that feature can be most closely represented in Dart, and what the C glue code looks like to support that feature. The more language features we can translate, the better the final product will be.
