 name: source_maps

-# Note! This version number is referenced directly in the pub source code in
-# lib/src/barback.dart. Pub implicitly places a version constraint on
-# source_maps to ensure users only select a version of source_maps that works
-# with their current version of pub.
-#
-# When the minor version is upgraded, you *must* update that version constraint
-# in pub to stay in sync with this.
