normalizeNotes function
Normalizes notes map for older API versions (maybe not needed with JSON serialization). Kept for parity if specific API endpoints require this format.
Implementation
Map<String, dynamic> normalizeNotes(Map<String, dynamic>? notes) {
if (notes == null) {
return {};
}
final normalized = <String, dynamic>{};
notes.forEach((key, value) {
normalized['notes[$key]'] = value;
});
return normalized;
}
