- The only OS supported for building Android and Linux desktop is Ubuntu 20.04. Windows builds require using Ubuntu 20.04 on WSL2. macOS builds for itself and iOS. Advanced users may also be able to build on other Debian-based distributions like Linux Mint.
The following instructions are for building and running on a Linux host. Alternatively, see the [Mac](#mac-host) and/or [Windows](#windows-host) section. This entire section (except for the Android Studio section) needs to be completed in WSL if building on a Windows host.
Install Flutter 3.19.6 by [following their guide](https://docs.flutter.dev/get-started/install/linux/desktop?tab=download#install-the-flutter-sdk). You can also clone https://github.com/flutter/flutter, check out the `3.19.6` tag, and add its `flutter/bin` folder to your PATH as in
Install Android Studio. Follow instructions here [https://developer.android.com/studio/install#linux](https://developer.android.com/studio/install#linux) or install via snap:
Then in `File > Settings > Plugins`, install the **Flutter** and **Dart** plugins and restart the IDE. In `File > Settings > Languages & Frameworks > Flutter > Editor`, 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`). Run `flutter doctor` to install any missing dependencies and review and agree to any license agreements.
To build coinlib on Linux, you will need `docker` (see [installation instructions](https://docs.docker.com/engine/install/ubuntu/)) or [`podman`](https://podman.io/docs/installation) (`sudo apt-get -y install podman`)
##### Remove system packages (may be needed for building flutter_libmonero)
[`flutter_libmonero`](https://github.com/cypherstack/flutter_libmonero) may have issues building due to conflicts with system packages: if so, follow this section.
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.*'
```
<!-- TODO: configure compiler to prefer built over system libraries. Should already use them? -->
Note on Emulators: Only x86_64 emulators are supported, x86 emulators will not work. You should [configure KVM](https://help.ubuntu.com/community/KVM/Installation) for much better performance.
XCode, Homebrew and several homebrew packages, Rust, and Flutter are required for Mac development with the Flutter SDK. Multiple IDEs may work, but Android Studio is recommended.
Download and install Xcode at https://developer.apple.com/xcode/, register your device (Mac or iPhone), and enable developer mode for your device as applicable. After installing XCode, make sure commandline tools are installed with `xcode-select --install`.
Download and install [Rust](https://www.rust-lang.org/tools/install). [Rustup](https://rustup.rs/) is recommended for Rust setup. Use `rustc` to confirm successful installation. Install toolchains 1.67.1 and 1.72.0 and `cbindgen` and `cargo-lipo` too. You will also have to add the platform target(s) `aarch64-apple-ios` and/or `aarch64-apple-darwin`. You can use the command(s):
Optionally download [Android Studio](https://developer.android.com/studio) as an IDE and activate its Dart and Flutter plugins. VS Code may work as an alternative, but this is not recommended.
Install [Flutter](https://docs.flutter.dev/get-started/install) 3.16.8 on your Mac host by following [these instructions](https://docs.flutter.dev/get-started/install/macos). Run `flutter doctor` in a terminal to confirm its installation.
Visual Studio is required for Windows development with the Flutter SDK. Download it at https://visualstudio.microsoft.com/downloads/ and install the "Desktop development with C++", "Linux development with C++", and "Visual C++ build tools" workloads. You may also need the Windows 10, 11, and/or Universal SDK workloads depending on your Windows version.
Set up Ubuntu 20.04 in WSL2. Follow the entire Linux host section in the WSL2 Ubuntu 20.04 host to get set up to build. The Android Studio section may be skipped in WSL (it's only needed on the Windows host).
The WSL2 host may optionally be navigated to the `stack_wallet` repository on the Windows host in order to build the plugins in-place and skip the next section in which you copy the `dll`s from WSL2 to Windows. Then build windows `dll` libraries by running the following script on the WSL2 Ubuntu 20.04 host:
-`stack_wallet/scripts/windows/build_all.sh`
Copy the resulting `dll`s to their respective positions on the Windows host:
Install Flutter 3.19.6 on your Windows host (not in WSL2) by [following their guide](https://docs.flutter.dev/get-started/install/windows/desktop?tab=download#install-the-flutter-sdk) or by cloning https://github.com/flutter/flutter, checking out the `3.19.6` tag, and adding its `flutter/bin` folder to your PATH as in
```bat
@echo off
set "FLUTTER_DIR=%USERPROFILE%\development\flutter"
Install [Rust](https://www.rust-lang.org/tools/install) on the Windows host (not in WSL2). Download the installer from [rustup.rs](https://rustup.rs), make sure it works on the commandline (you may need to open a new terminal), and install the following versions:
Install the Windows SDK: https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/ You may need to install the [Windows 10 SDK](https://developer.microsoft.com/en-us/windows/downloads/sdk-archive/), which can be installed [by Visual Studio](https://stackoverflow.com/a/73923899) (`Tools > Get Tools and Features... > Modify > Individual Components > Windows 10 SDK`).
or [download the package](https://www.nuget.org/packages/Microsoft.Windows.CppWinRT/2.0.210806.1) and [manually install it](https://github.com/Baseflow/flutter-permission-handler/issues/1025#issuecomment-1518576722) by placing it in `flutter/bin` with [nuget.exe](https://dist.nuget.org/win-x86-commandline/latest/nuget.exe) and installing by running `nuget install Microsoft.Windows.CppWinRT -Version 2.0.210806.1` in the root `stack_wallet` folder.
<!-- TODO: script this NuGet and WinCppRT installation -->
Certain test wallet parameter and API key template files must be created in order to run Stack Wallet on Windows. These can be created by script using PowerShell on the Windows host as in
Run with `-v` or `--verbose` to see a more detailed error. Certain exceptions (like missing a plugin library) may not report quality errors without `verbose`, especially on Windows.
To test Tor usage, run Stack Wallet from Android Studio. Click the Flutter DevTools icon in the Run tab (next to the Hot Reload and Hot Restart buttons) and navigate to the Network tab. Connections using Tor will show as `GET InternetAddress('127.0.0.1', IPv4) 101 ws`. Connections outside of Tor will show the destination address directly (although some Tor requests may also show the destination address directly, check the Headers take for *eg.*`{localPort: 59940, remoteAddress: 127.0.0.1, remotePort: 6725}`. `localPort` should match your Tor port.
