# Flutter (https://flutter.dev) Developement 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.
