We're using Flutter at work for one of our applications, so I can 
answer that.

The Flutter project is divided in two parts: engine and 
framework. The engine is written in a mix of C++, Java and 
Objective-C where Java and Objective-C are respectively used to 
access the platform APIs. The framework (what Flutter apps are 
directly using) is written in pure Dart.
Flutter is using a technique called system channels which is 
basically an RPC-like thing that marshals method calls to/from 
C/C++/Java/Objective-C from/to C++ and Dart. It's slower than 
calling the method from the same language.

I believe Flutter will be framework of choice for their upcoming 
Fuchsia OS, but currently Dart is very much a second class 
citizen on Android (unlike Kotlin), just like it is on iOS. 
Fortunately, Google have done a stellar job of creating good dev 
experience by providing a solid CLI and editor plugins that 
abstract the platform differences.
