Building

Prerequisites

• The only OS supported for building is Ubuntu 20.04
• A machine with at least 100 GB of Storage

The following prerequisities can be installed with the setup script scripts/setup.sh or manually as described below:

• Flutter 3.0.5 (install manually or with git, do not install with snap)
• Dart SDK Requirement (>=2.17.0, up until <3.0.0)
• Android setup (Android Studio and subsequent dependencies)

Scripted setup

scripts/setup.sh is provided as a tool to set up a stock Ubuntu 20.04 installation for building: download the script and run it anywhere. This script should skip the entire Manual setup section below and prepare you for running. It will set up the stack_wallet repository in ~/projects/stack_wallet and build it there.

Manual setup

After installing the prerequisites listed above, download the code and init the submodules

git clone https://github.com/cypherstack/stack_wallet.git
cd stack_wallet
git submodule update --init --recursive

Install all dependencies listed in each of the plugins in the crypto_plugins folder (eg. flutter_libmonero, flutter_libepiccash ) as of Oct 3rd 2022 that is:

sudo apt-get install unzip automake build-essential file pkg-config git python libtool libtinfo5 cmake openjdk-8-jre-headless libgit2-dev clang libncurses5-dev libncursesw5-dev zlib1g-dev llvm sudo apt-get install debhelper libclang-dev cargo rustc opencl-headers libssl-dev ocl-icd-opencl-dev

Install Rust

cargo install cargo-ndk
rustup target add aarch64-linux-android armv7-linux-androideabi i686-linux-android x86_64-linux-android

sudo apt install libc6-dev-i386
sudo apt install build-essential cmake git libgit2-dev clang libncurses5-dev libncursesw5-dev zlib1g-dev pkg-config llvm 
sudo apt install build-essential debhelper cmake libclang-dev libncurses5-dev clang libncursesw5-dev cargo rustc opencl-headers libssl-dev pkg-config ocl-icd-opencl-dev
sudo apt install unzip automake build-essential file pkg-config git python libtool libtinfo5 cmake openjdk-8-jre-headless

Run prebuild script

cd scripts
./prebuild.sh
// when finished go back to the root directory
cd ..

Remove pre-installed system libraries for the following packages built by cryptography plugins in the crypto_plugins folder: boost iconv libjson-dev libsecret openssl sodium unbound zmq. You can use

sudo apt list --installed | grep boost

for example to find which pre-installed packages you may need to remove with sudo apt remove. Be careful, as some packages (especially boost) are linked to GNOME (GUI) packages: when in doubt, remove -dev packages first like with

sudo apt-get remove '^libboost.*-dev.*'

Building plugins for Android

cd scripts/android/
./build_all.sh
// when finished go back to the root directory
cd ../..

Building plugins for Linux

cd scripts/linux/
./build_all.sh
// when finished go back to the root directory
cd ../..

Running

Android

Plug in your android device or use the emulator available via Android Studio and then run the following commands:

flutter pub get
flutter run android

Note on Emulators: Only x86_64 emulators are supported, x86 emulators will not work

Linux

Plug in your android device or use the emulator available via Android Studio and then run the following commands:

flutter pub get Linux
flutter run linux

Android Studio

Android Studio is the recommended IDE for development, not just for launching on Android devices and emulators but also for Linux desktop development. Install it and configure it as follows:

# setup android studio
sudo apt install -y openjdk-11-jdk
sudo snap install android-studio --classic

Use Tools > SDK Manager to install the SDK Tools > Android SDK (API 30), SDK Tools > NDK, SDK Tools > Android SDK command line tools, and SDK Tools > CMake

Then install the Flutter plugin and restart the IDE. In Android Studio's options for the Flutter language, enable auto format on save to match the project's code style. If you have problems with the Dart SDK, make sure to run flutter in a terminal to download it (use source ~/.bashrc to update your environment variables if you're still using the same terminal from which you ran setup.sh)

Make a Pixel 4 (API 30) x86_64 emulator with 2GB of storage space for emulation
