There's been a C dart FFI for years. Communicating with whichever other system shouldn't be any harder than the next language. None of those would be my first choice though. The less platform specific code you write, the fewer platform specific issues you'll be dealing with. Plus xamarin isn't native anywhere.
With Flutter apps using the AOT, performance should already be good. Here's an interesting real world comparison between libsass (a C library) and dartsass.

s C/C++ code is compiled with LLVM, and any Dart code is AOT-compiled into native code. The app runs using the native instruction set (no interpreter is involved).
> Can I access platform services and APIs like sensors and local storage?
> Yes. Flutter gives developers out-of-the-box access to some platform-specific services and APIs from the operating system. However, we want to avoid the “lowest common denominator” problem with most cross-platform APIs, so we do not intend to build cross-platform APIs for all native services and APIs.
> A number of platform services and APIs have ready-made packages available in the Pub repository. Using an existing package is easy.
> Finally, we encourage developers to use Flutter’s asynchronous message passing system to create your own integrations with platform and third-party APIs. Developers can expose as much or as little of the platform APIs as they need, and build layers of abstractions that are a best fit for their project.
