CSA Flutter Demo

Simple showcase for Flutter on Codesphere using the default Flutter Application template.

Development Setup

Prerequisites

• Flutter SDK (>=3.0.0)
• Dart SDK (>=3.0.0)

Running the Application locally

cd demo_app
flutter pub get
flutter run -d web-server --web-port 8080

App will be available at http://localhost:8080

Buiding the WebApp

cd demo_app
flutter clean && flutter pub get
flutter build web

The built app can be found and served from demo_app/build/web, e.g. with simple webserver.

Building the Android APK

cd demo_app
nix develop --extra-experimental-features nix-command --extra-experimental-features flakes

This will create a Nix devShell environment with Flutter and the Android SDK installed. The Android SDK has various configuration option, like the API levels, which are containing in the Nix flake flake.nix.

When in the devShell:

cd demo_app
flutter build apk --release
