Click on notification should open the email

[bedhub]

When clicking on a notification i expect that the tuta app opens so that i can read the content of the email that i have received the notification for.

AC

• Click on notification opens the app and selects the corresponding mail in the list.
• Mail can be displayed before synchronization is done
• Works on Web, iOS, Android and Desktop app
• Mail instance is not loaded again.
• In case the mail has been deleted we show a info message (SnackBar) that the mail has been deleted.

Notes

What should happen if the mail has not been loaded yet?

 Option1: Wait for synchronization and then select the mail  Option2: Load the mail before synchronization, event if it is not in the list.

→ Try option 2

What happens if the mail has been moved to different folder or deleted?

Option1: In case the email cannot be loaded show a non blocking snackbar. Option2: We have the mail already available in the notification, we could reuse the loaded entity and use that to load MailDetails.

→ Try option 2
