Right now I have a notification set up with local_notifications, problem is, it has the same body every single day.
How do I create daily notifications where the body is, for example, a random string from a list that is new each day?
This seems very common to have in apps, I have despite of that not found anything helpful so far.
Personally, I would save a variable with todays date using SharedPreferences and the DateTime package. Then, every time that you need to push a notification, I would compare today's date with the date that you've stored in Shared Preferences, and then return a random string from your list. Like so:
// call this when you want to send an notification
void pushDailyNotification(List<String> appStrings, SharedPreferences prefs) async {
final random = Random();
// random index from your list of strings
int todayString = appStrings[random.nextInt(appStrings.length)];
String savedDate = prefs.getString('date') ?? DateTime.now().toString();
int today = DateTime.now().day;
if(today != DateTime.tryParse(savedDate).day){
// if the date that you've saved isn't the same as today's, its a new day, so return a new random string
String newNotificationBody = appStrings[random.nextInt(appStrings.length)];
await flutterLocalNotificationsPlugin.show(
0, "It's a new day!", newNotificationBody, platformChannelSpecifics,
payload: 'item x');
prefs.setString('date', DateTime.now().toString());
// save today's date for next time
}
else {
// show a notification with the same body as last time
await flutterLocalNotificationsPlugin.show(
0, "It's a new day!", appStrings[todayString], platformChannelSpecifics,
payload: 'item x');
}
}
This may not fit with the exact setup of your project, but I hope this gives you an idea of what you could do. Use SharedPreferences and Random to help you.
