Flutter Development Environment

A simple Nix setup for Flutter development with Android testing options.

Key Features

• Flutter and Dart SDK development environment
• Android SDK with build tools
• Two options for testing Android apps:
  • Standard Android Emulator (using default.nix)
  • Waydroid for native Wayland support (using flake.nix)

Quick Start

Method 1: Android Emulator (recommended for most cases)

# Build and run the emulator
nix-build default.nix
./result/bin/run-test-emulator

Method 2: Flutter + Waydroid (for Wayland environments)

# Setup in NixOS configuration.nix
virtualisation.waydroid.enable = true;

# Enter development environment
nix develop

# Start Waydroid
sudo waydroid init -s GAPPS -f
sudo systemctl start waydroid-container
waydroid session start
waydroid show-full-ui

Flutter Workflow

# Create new project
flutter create my_app
cd my_app

# Build your app
flutter build apk

# Install on Android Emulator
adb install build/app/outputs/flutter-apk/app-release.apk

# Or install on Waydroid
waydroid app install build/app/outputs/flutter-apk/app-release.apk

Troubleshooting

Android Emulator Issues

If you have problems with the emulator:

• Try with JDK8 instead of JDK17 if the AVD manager fails
• Ensure KVM is enabled: sudo modprobe kvm
• Check virtualization is enabled in BIOS/UEFI

Waydroid Issues

For GPU performance problems:

echo "ro.hardware.gralloc=default
ro.hardware.egl=swiftshader" | sudo tee -a /var/lib/waydroid/waydroid_base.prop
