# Flutter web build, served as static files by nginx.
#
# Dokploy builds this repo with its Dockerfile provider, so the image does the
# whole job: install the Flutter SDK, compile the web bundle, hand the output to
# a web server. Nothing from the build stage survives into the final image but
# build/web.
#
# The SDK comes from the official archive at a pinned version rather than from a
# `flutter:stable` image: those images trail the real stable channel, and the
# one tagged stable ships a Dart older than the SDK floor in pubspec.yaml, so
# `pub get` refuses to resolve. Keep FLUTTER_VERSION in step with the toolchain
# the app is developed against.
