This sample builds a native library for adding and multiplying. It then uses the recorded usages feature to tree-shake unused libraries out.

Usage:

Keep all:

dart --enable-experiment=native-assets,record-use build bin/drop_dylib_recording_all.dart

The lib/ folder now contains both libraries

./bin/drop_dylib_recording_all/drop_dylib_recording_all.exe add

Prints Hello world: 7!

Treeshake using calls:

dart --enable-experiment=native-assets,record-use build bin/drop_dylib_recording_calls.dart

The lib/ folder now contains only the add library.

./bin/drop_dylib_recording_calls/drop_dylib_recording_calls.exe

Prints Hello world: 7!

Treeshake using instances:

dart --enable-experiment=native-assets,record-use build bin/drop_dylib_recording_instances.dart

The lib/ folder now contains only the add library.

./bin/drop_dylib_recording_calls/drop_dylib_recording_instances.exe

Prints Hello world: 7!
