Project Stucture #
This template uses the following structure:


lib: Contains the Dart code that defines the API of the plugin, and which
calls into the native code using dart:ffi.


src/cpp: Contains the native source code, and a CMakeLists.txt file for building
that source code into a dynamic library.


platform folders (android & ios): Contains the build files for building and bundling
the native code library with the platform application.
