# Dockerfile.flutter-ci — Flutter SDK image for CI use.
#
# Built on top of the official Dart Docker image and installs a pinned Flutter
# SDK release. Used by .woodpecker/android.yml to run `flutter analyze` and
# `flutter test` without downloading the SDK on every CI run.
#
# To build and push (replace TAG with the Flutter SDK version, e.g. 3.32.0):
#
#   docker build --build-arg FLUTTER_VERSION=3.32.0 \
#     -t codeberg.org/snonux/player/flutter-ci:3.32.0 \
#     -f Dockerfile.flutter-ci .
#   docker push codeberg.org/snonux/player/flutter-ci:3.32.0
#
# Update .woodpecker/android.yml to reference the new tag when upgrading.
