Yes, you need to install the Web SDK from https://webdev.dartlang.org/tools/sdk#install to use this package. The two SDKs can coexist. Flutter bundles a stripped down Dart SDK under bin/cache/dart-sdk. Make sure you do not have it in your PATH. Instead put the Web SDK in your PATH. Otherwise when you call the dart or pub commands you will end up using the Flutter versions.
