Fix / Notification - Prevent notification if user is already declared or has set absence

[NyraSama]

🗒️NOTES

Currently we receive a notification everyday at 9 o clock. But if we do our declaration at 8 o clock we want to not have any notification.

In order to achieve this result, we expose native methods that we will create in Swift and Kotlin

scheduleNotification{Platform}(timestamp, title, message) // timestamp: string ISO8601

We then schedule two months worth of notifications from flutter, when the app is launched, or when a new declaration occured.

🏁PREREQUISITES

• [x] DOR
• [ ] DOD

📜CONTEXT (User Story)

As a user

I want to receive a daily notification only if i am not already declared

In order to not forget to declare me

🪳STEPS TO REPRODUCE

• Step 1: Connect to mobile app before 9 a.m
• Step 2: Do your daily declaration
• Step 3: Leave the app
• Step 4: Wait to receive a notification around 9 a.m

🪜STEPS FOR A FIX

Swift

• [x] Step 1: Create a new Swift method in the channel:
  • scheduleNotificationSwift(timestamp: String, title: String, message: String) With the timestamp following ISO8601
• [x] Step 2: Create a new Swift method in the channel:
  • cancelAllNotificationsSwift()
• [x] Step 3: Create a method on the Flutter Side that is triggered on launch (and on declarations) which executes the following pseudocode:
• [x] Additional Step: Exclude public holidays in metropolitan France.

  cancelAllNotificationsSwift()
  declaredDates <- getDeclaredDates() // from repo
  for i <- 1..60
  currentDay <- addDays(today(), i)
  if currentDay in declaredDates
      continue
  timestamp <- timestampFrom(addHours(currentDay, 8))
  scheduleNotificationSwift(timestamp, title, message)

Kotlin

• [x] Step 4: Create a new Kotlin method in the channel:
  • scheduleNotificationKotlin(timestamp: String, title: String, message: String) With the timestamp following ISO8601
• [ ] Step 5: Create a new Swift method in the channel:
  • cancelAllNotificationsKotlin()
• [ ] Step 6: Modify the flutter method to conditionally use the correct platform

  if Platform.isAndroid
  cancelAllNotificationsKotlin()
  if Platform.isIOS
  cancelAllNotificationsSwift()
  ...
  if Platform.isAndroid
  scheduleNotificationKotlin(...)
  if Platform.isIOS
  scheduleNotificationSwift(...)

✅ACCEPTANCE CRITERIA

• ⛔Notification doesn't appear a day where the user have done his declaration
