base_ property
Base is the branch to start FROM. Empty means the repository's default — resolve it on the machine, since the machine is the one holding the clone.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? base_;
