id property
ID is the environment's name, which is also its identity — an environment is derived from the apps that target it, so it has no id of its own.
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? id;
