Emulation (Android Studio)​

Welcome to the Karter project! To contribute you need to configure your environment for Flutter and Android development.

Prerequisites​

Before starting, ensure you have the following installed:

  • Flutter SDK: Version 3.19.0 or higher.
  • Android Studio: Latest version for SDK and Emulator management.
  • Fedora/Linux Tools: If you are on Fedora, install the build dependencies: 
    sudo dnf install clang cmake ninja-build pkgconf-pkg-config gtk3-devel liblzma-devel

1. Android Toolchain Configuration​

Flutter requires specific Android components.

Install Command-line Tools​

  1. Open Android Studio.
  2. Go to Settings > Languages & Frameworks > Android SDK.
  3. Select the SDK Tools tab.
  4. Check Android SDK Command-line Tools (latest) and click Apply.

Accept Licenses​

Run the following command in your terminal and accept all prompts:

flutter doctor --android-licenses

Real Devices​

If you have a physical Android device, scrcpy is the fastest way to develop. It mirrors your phone to your desktop with zero lag and minimal CPU usage.

Enable USB Debugging on your phone.

Install scrcpy:

sudo dnf install scrcpy
``

Connect your phone and run:

```bash
scrcpy --always-on-top --show-touches

Emulation (No Android Studio)​

If you prefer a virtual device but want to avoid opening Android Studio:

Create an AVD: Use avdmanager create avd -n KarterDevice -k "system-images;android-34;google_apis;x86_64".

emulator -avd KarterDevice -netdelay none -netspeed full
