How to get into Dart Docker container's shell?

I'm trying to access the my Dart Docker container's shell

$ docker-compose exec dartserver sh

but I'm getting this error message:

OCI runtime exec failed: exec failed: container_linux.go:380: starting container process caused: exec: "sh": executable file not found in $PATH: unknown

Any idea?

Dockerfile

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"]

The scratch image default don't have shell in it. If you really want to access shell, what I suggest is to use busybox image.

See busybox dockerfile:

FROM scratch
ADD busybox.tar.xz /
CMD ["sh"]

It's also based on scratch, but with shell enable, additionally it's still very small.
