-# 📰 NEWS
-- The layout of this repo changed a bit.
-- I now provide 2 versions of the engine, one debug version and one release version.
-- flutter-pi loads `libflutter_engine.so.debug`, or `libflutter_engine.so.release` if `--release` was given via cmdline.
-- if `libflutter_engine.so.debug` or `libflutter_engine.so.release` could not be found by flutter-pi, it will try to load `libflutter_engine.so`.
-- don't forget to delete your old `libflutter_engine.so`, since it's not overwritten when copying the new libraries
-- `gen_snapshot_linux_x64` is for building the `app.so` to run your App in release mode. The binary must be executed on a Linux x64 machine. (If you're on Windows, just use WSL). Instructions WIP
