# Test for changed transitive import but unchanged direct import.
# Currently (before the fix for it) this happens:
#   First compile:
#     * a: hash(a.dart, foo=path/to/foo=3.12) - new and saved.
#     * b: hash(b.dart) - new and saved
#     * c: hash(c.dart) - new and saved
#     (technically "package:foo/nomatter.dart" is saved too but that's not
#     important here)
#   Second compile:
#     * a: hash(a.dart) - new and saved
#     * b: hash(b.dart) - loaded from cache but invalidated because of c, saved
#     * c: hash(c.dart) - loaded but changed (so "new") and saved
#   Third compile:
#     * a: hash(a.dart, foo=path/to/foo=3.12) - loaded from cache
#     * b: hash(b.dart) - loaded from cache
#     * c: hash(c.dart) - loaded from cache
#   At the third compile stuff no longer fits together though.
