Flutter how to create a loop in else if - flutter

Question

i got a chart that display months (in french) when i go below the month == 1, i would like to go back to my current month and not see my 'error'.
Is there a method to make it ?
String numericToStringMonth(int month) {
if (month < 1 || month > 12) {
return 'error';
} else if (month == 1) {
return 'Janvier';
} else if (month == 2) {
return 'Février';
} else if (month == 3) {
return 'Mars';
} else if (month == 4) {
return 'Avril';
} else if (month == 5) {
return 'Mai';
} else if (month == 6) {
return 'Juin';
} else if (month == 7) {
return 'Juillet';
} else if (month == 8) {
return 'Août';
} else if (month == 9) {
return 'Septembre';
} else if (month == 10) {
return 'Octobre';
} else if (month == 11) {
return 'Novembre';
} else if (month == 12) {
return 'Décembre';
} else {
return 'error';
}
}

String numericToStringMonth(int month) {
// make list of months for easier access
List<String> months = [
'Janvier',
'Février',
'Mars',
'Avril',
'Mai',
'Juin',
'Juillet',
'Août',
'Septembre',
'Octobre',
'Novembre',
'Décembre'
];
int currentMonth = month - 1;
try {
if (currentMonth > 11) {
throw Exception('Month must be between 1 and 12');
} else if (currentMonth < 0) {
// setting month to the first one when value goes below 0, add your logic here
currentMonth = 1;
}
return months[currentMonth];
} catch (e) {
print(e);
}
return '';
}
