Building app for Linux musl? about sdk

[mark-dropbear]

Just to let you know you don't need to use Alpine and you can go even more minimal just by using the built in Dockerfile that already comes with dart create -t server-shelf but pasting here for reference as well.

# Use latest stable channel SDK.
FROM dart:stable AS build

# Resolve app dependencies.
WORKDIR /app
COPY pubspec.* ./
RUN dart pub get

# Copy app source code (except anything in .dockerignore) and AOT compile app.
COPY . .
RUN dart compile exe bin/server.dart -o bin/server

# Build minimal serving image from AOT-compiled `/server`
# and the pre-built AOT-runtime in the `/runtime/` directory of the base image.
FROM scratch
COPY --from=build /runtime/ /
COPY --from=build /app/bin/server /app/bin/

# Start server.
EXPOSE 8080
CMD ["/app/bin/server"]

You need to use Dart SDK which is built for Alpine, i.e. https://pkgs.alpinelinux.org/package/edge/testing/x86_64/dart-sdk. That would contain Dart runtime which links against musl.
