First I have to convert the integer to time (which I've managed to do so far) and then I want to schedule a notification on that time. You see that checkbox, When someone taps then alarm is set. So I don't multiple alarms. And most importantly I can't flutter default time picker (That works) but I can't use since I'm setting the alarm with my default time picker.
Now I want to take that value and convert that to time and set a notification on that time. Thanks everyone in advance Alarm App Screen
I've tried flutter local notifications package but I can't seem to figure out how can I take the integer value and set it to schedule notification.enter image description here

I am creating an app where it will send you a local notification every 20 minutes. The problem I am having is once the app goes into background mode, the timer which triggers the function to run which executes some code then sends the user a notification won't run. Is there any alternative way of doing this? This timer runs on a loop, reseting its self every 20 minutes and running a function.
Thanks
Sure. Check out the documentation for UILocalNotification. You can set a fireDate to the exact second when you want the notification to go off. It also has parameters you can use to specify a repeat interval.
You cannot force the user to activate the app to run your function. Once the user taps the notification and your app becomes active, you can then perform all the logic you require (perhaps also including dealing with past "missed" notifications) .
I have set localnotications to fire 3 times everyday using UILocalnotification class in iPhone. notications are getting triggered correctly. I want to show the list of notications which will fire today. I am saving timings of all notications in text format into my database. How can I resolve it?
i'm looking at displaying the current time in HH:mm format, and ive been checking around for the best way to do this.
Most examples have a Timer being executed every second, updating a textlabel for example.
Now, i'm imagining that this might drain a bit of battery if it's to run every second, which seems like overkill if all i'm displaying is hours and minutes. On the other hand, i don't want the minute-switch to happen 30 seconds later than the actual minute switch...
Is there some way to get a call when the phone clock changes minute or something like that?
Don't worry about the battery. NSTimer exists for this purpose. Use it!
Here's an idea:
Calculate the time interval between now and the next minute start
schedule a one off NSTimer to fire after that time interval
update the display when it fires
Go back to step 1.
I am making one application in which the location needs to be updated after every 2 hours from background, i have implemented CLLocationManager and it is working absolutely fine and is calling , however if i implement timer from background for certain time interval it didn't work and if i put the app in sleep mode for that few seconds like 300, it awakes twice or thrice not more than that,when the home button is pressed i stopped the location and after sleep it again start the location update and then again stop ,so how it is possible to get the proper location update after 2 hours plz help
You can use UILocalNotification for updating the Location every 2 hours..
Instances of UILocalNotification represent notifications that an application can schedule for presentation to its users at specific dates and times. The operating system is responsible for delivering the notification at the proper time; the application does not have to be running for this to happen.
I've got an iPhone application, and I'd like it to reset its state every time the user leaves it, i.e. the home button is pressed. By "reset its state" I mean that the application should start as if it was started for the first time, and not resume from where the user left it. How can I implement this?

As you said, you theoretically could set that Boolean value in the info.plist file. However, you lose a lot of information like this. I recommend storing initial values in your app and load them every time te app starts. Tie your UI to those values.
