toJson method
Only the sections present — the merge unit on the attacher side.
Implementation
Map<String, Object?> toJson() => {
if (baseUrl != null) 'baseUrl': baseUrl,
if (environment != null) 'environment': environment,
if (links != null) 'links': [for (var link in links!) link.toJson()],
if (connections != null)
'connections': [for (var c in connections!) c.toJson()],
if (config != null) 'config': config,
};
