Please Provide Build Instructions + Dockerfile

Greetings team @ProtonWallet!

Hi! I'm Danny and I work with walletscrutiny.com. We verify the reproducibility of Bitcoin apps and devices. We have scrutinized over 6000+ bitcoin-related apps and devices.

I am trying to build from the command line using this Dockerfile, but always wound up with some errors:

RUN flutter pub get

# Expose the terminal for interactive debugging
CMD ["/bin/bash"]

From there I run $ docker build -t proton-build .

Then run:

docker run --rm -it proton-build

Inside the workspace directory I move to ./rust to find the cargo.toml file. I then try to run:

cargo build --target aarch64-linux-android --release --verbose

which results in:

error: failed to parse manifest at `/workspace/rust/Cargo.toml`

Caused by:
  registry index was not found in any configuration: `proton_internal`

From my understanding, this seems to be an internal registry that is causing the build to fail.

Request to provide Dockerfile to build the app

My first request is for the provision for explicit build instructions done via the terminal, and related to this:
The provision of an official Dockerfile that could build the app from source.

We would appreciate it!
