4. Add the language to `lib/entities/language_service.dart` under both `supportedLocales` and `localeCountryCode`. Use the name of the language in the local language and in English in parentheses after for `supportedLocales`. Use the [ISO 3166-1 alpha-3 code](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-3) for `localeCountryCode`. You must choose one country, so choose the country with the most native speakers of this language or is otherwise best associated with this language.
5. Add a relevant flag to `assets/images/flags/XXXX.png`, replacing XXXX with the 3 digit localeCountryCode. The image must be 42x26 pixels with a 3 pixels of transparent margin on all 4 sides. You can resize the flag with [paint.net](https://www.getpaint.net/) to 36x20 pixels, expand the canvas to 42x26 pixels with the flag anchored in the middle, and then manually delete the 3 pixels on each side to make transparent. Or you can use another program like Photoshop.

# Building CakeWallet for Linux
## Requirements and Setup
The following are the system requirements to build CakeWallet for your Linux device.
```
Ubuntu >= 16.04
Flutter 3.10.x
```
## Building CakeWallet on Linux
These steps will help you configure and execute a build of CakeWallet from its source code.
### 1. Installing Package Dependencies
CakeWallet requires some packages to be install on your build system. You may easily install them on your build system with the following command:
`$ sudo apt install build-essential cmake pkg-config git curl autoconf libtool`
> [!WARNING]
>
> ### Check gcc version
>
> It is needed to use gcc 10 or 9 to successfully link dependencies with flutter.\
> To check what gcc version you are using:
>
> ```bash
> $ gcc --version
> $ g++ --version
> ```
>
> If you are using gcc version newer than 10, then you need to downgrade to version 10.4.0:
>
> ```bash
> $ sudo apt install gcc-10 g++-10
> $ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 10
> $ sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-10 10
> ```

### 2. Installing Flutter
Need to install flutter. For this please check section [How to install flutter on Linux](https://docs.flutter.dev/get-started/install/linux).
### 3. Verify Installations
Verify that the Flutter have been correctly installed on your system with the following command:
`$ flutter doctor`
The output of this command will appear like this, indicating successful installations. If there are problems with your installation, they **must** be corrected before proceeding.
```
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, 3.10.x, on Linux, locale en_US.UTF-8)
```
### 4. Acquiring the CakeWallet Source Code
Download CakeWallet source code
`$ git clone https://github.com/cake-tech/cake_wallet.git --branch linux/password-direct-input`
Proceed into the source code before proceeding with the next steps:
`$ cd cake_wallet/scripts/linux/`
To configure some project properties run:
`$ ./cakewallet.sh`
Build the Monero libraries and their dependencies:
`$ ./build_all.sh`
Now the dependencies need to be copied into the CakeWallet project with this command:
`$ ./setup.sh`
It is now time to change back to the base directory of the CakeWallet source code:
`$ cd ../../`
Install Flutter package dependencies with this command:
`$ flutter pub get`
> #### If you will get an error like:
>
> ```
> The plugin `cw_shared_external` requires your app to be migrated to the Android embedding v2. Follow the steps on the migration doc above and re-run
> this command.
> ```
>
> Then need to config Android project settings. For this open `scripts/android` (`$ cd scripts/android`) directory and run followed commands:
>
> ```
> $ source ./app_env.sh cakewallet
> $ ./app_config.sh
> $ cd ../..
> ```
>
> Then re-configure Linux project again. For this open `scripts/linux` (`$cd scripts/linux`) directory and run:
> `$ ./cakewallet.sh`
> and back to project root directory:
> `$ cd ../..`
> and fetch dependecies again
> `$ flutter pub get`
Your CakeWallet binary will be built with some specific keys for iterate with 3rd party services. You may generate these secret keys placeholders with the following command:
`$ flutter packages pub run tool/generate_new_secrets.dart`
We will generate mobx models for the project.
`$ ./model_generator.sh`
Then we need to generate localization files.
`$ flutter packages pub run tool/generate_localization.dart`
### 5. Build!
`$ flutter build linux --release`
Path to executable file will be:
`build/linux/x64/release/bundle/cake_wallet`
> ### Troubleshooting
>
> If you got an error while building the application with `$ flutter build linux --release` command, add `-v` argument to the command (`$ flutter build linux -v --release`) to get details.\
> If you got in flutter build logs: undefined reference to `hid_free_enumeration`, or another error with undefined reference to `hid_*`, then rebuild monero lib without hidapi lib. Check does exists `libhidapi-dev` in your scope and remove it from your scope for build without it.
# Flatpak
For package the built application into flatpak you need fistly to install `flatpak` and `flatpak-builder`:
`$ sudo apt install flatpak flatpak-builder`
Then need to [add flathub](https://flatpak.org/setup/Ubuntu) (or just `$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo`). Then need to install freedesktop runtime and sdk:
`$ flatpak install flathub org.freedesktop.Platform//22.08 org.freedesktop.Sdk//22.08`
To build with using of `flatpak-build` directory run next:
`$ flatpak-builder --force-clean flatpak-build com.cakewallet.CakeWallet.yml`
And then export bundle:
`$ flatpak build-export export flatpak-build`
`$ flatpak build-bundle export cake_wallet.flatpak com.cakewallet.CakeWallet`
Result file: `cake_wallet.flatpak` should be generated in current directory.
For install generated flatpak file use:
`$ flatpak --user install cake_wallet.flatpak`
For run the installed application run:
`$ flatpak run com.cakewallet.CakeWallet`

# Building CakeWallet for Windows
## Requirements and Setup
The following are the system requirements to build CakeWallet for your Windows PC.
```
Windows 10 or later (64-bit), x86-64 based
Flutter 3 or above
```
## Building CakeWallet on Windows
These steps will help you configure and execute a build of CakeWallet from its source code.
### 1. Installing Package Dependencies
For build CakeWallet windows application from sources you will be needed to have:
> [Install Flutter]Follow installation guide (https://docs.flutter.dev/get-started/install/windows) and install do not miss to dev tools (install https://docs.flutter.dev/get-started/install/windows/desktop#development-tools) which are required for windows desktop development (need to install Git for Windows and Visual Studio 2022). Then install `Desktop development with C++` packages via GUI Visual Studio 2022, or Visual Studio Build Tools 2022 including: `C++ Build Tools core features`, `C++ 2022 Redistributable Update`, `C++ core desktop features`, `MVC v143 - VS 2022 C++ x64/x86 build tools`, `C++ CMake tools for Windwos`, `Testing tools core features - Build Tools`, `C++ AddressSanitizer`.
> [Install WSL] for building monero dependencies need to install Windows WSL (https://learn.microsoft.com/en-us/windows/wsl/install) and required packages for WSL (Ubuntu):
`$ sudo apt update `
`$ sudo apt build-essential cmake gcc-mingw-w64 g++-mingw-w64 autoconf libtool pkg-config`
### 2. Pull CakeWallet source code
You can downlaod CakeWallet source code from our [GitHub repository](github.com/cake-tech/cake_wallet) via git by following next command:
`$ git clone https://github.com/cake-tech/cake_wallet.git --branch MrCyjaneK-cyjan-monerodart`
OR you can download it as [Zip archive](https://github.com/cake-tech/cake_wallet/archive/refs/heads/MrCyjaneK-cyjan-monerodart.zip)
### 3. Build Monero, Monero_c and their dependencies
For use monero in the application need to build Monero wrapper - Monero_C which will be used by monero.dart package. For that need to run shell (bash - typically same named utility should be available after WSL is enabled in your system) with previously installed WSL, then change current directory to the application project directory with your used shell and then change current directory to `scripts/windows`: `$ cd scripts/windows`. Run build script: `$ ./build_all.sh`.
### 4. Configure and build CakeWallet application
To configure the application open directory where you have downloaded or unarchived CakeWallet sources and run `cakewallet.bat`.
Or if you used WSL and have active shell session you can run `$ ./cakewallet.sh` script in `scripts/windows` which will run `cakewallet.bat` in WSL.
After execution of `cakewallet.bat` you should to get `Cake Wallet.zip` in project root directory which will contains `CakeWallet.exe` file and another needed files for run the application. Now you can extract files from `Cake Wallet.zip` archive and run the application.
