# Flutter (https://flutter.dev) Development Environment for Linux
# ===============================================================
#
# This environment passes all Linux Flutter Doctor checks and is sufficient
# for building Android applications and running Flutter tests.
#
# To build iOS applications, a Mac development environment is necessary.
#
# This includes applications and sdks that are needed only by the CI system
# for performing pushes to production, and so this image is quite a bit larger
# than strictly needed for just building Flutter apps.

# Last manual update 2020-10-05 (changing this comment will re-build image)

# Note: updating past stretch (Debian 9) will bump Java past version 8,
# which will break the Android SDK.
