It is now possible import and export decks. Decks can be imported from
OPML files. For each import a new deck is created. If the OPML file
contains nested `outline` tags, we will create one column for each
parent `outline` tag. Otherwise we will create a column named `Unknown`
and all sources to this column. When a deck is exported we will create
one `outline` tag for each column with it's sources as siblings.
Update Flutter to Version 3.24.0 and replace the deprecated `background`
and `onBackground` colors with `surface` and `onSurface`. Within this
migration we also adjusted the `onSecondary` color, so that the apps
look as before the update.
We have to add in-app purchases for the iOS, macOS and Android store, so
that users can also get the premium features of the app without using
Stripe for payments.
The in-app purchases are only enabled when a user uses the app with the
default Supabase environment or with the Supabase environment provided
during build time. If a user uses his own Supabase instance, he will not
be able to upgrade to the premium tier via in-app purchases.
We are using RevenueCat for in-app purchases, which automatically sends
all the events for a user to the "revenuecat-webhooks-v1" edge function.
Depending on the received event we can then upgrade / downgrade the
users profile. To be able to use RevenueCat as an additional provider to
Stripe we also had to add a new "subscriptionProvider" provider column
to the "profiles" table, which stores the information via which provider
a user upgraded his account.
The settings page now contains an info section, which is used to show
the current app version via the "package_info_plus" package, the link to
our website, the link to our GitHub repository and the link to our X
account.
