Upgrade the used version of Flutter to 3.19.1 and all used packages to
their latest version.
For the Android Version of the app, we also had to adjust some files,
because of the "Deprecated imperative apply of Flutter's Gradle
plugins". The steps we had to run for this can be found at
https://docs.flutter.dev/release/breaking-changes/flutter-gradle-plugin-apply
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.
During the review of the submission of the iOS and macOS versions of
FeedDeck we encountered some problems, so that the app was rejected. For
that we had to make the following changes:
- Change the foreground and background color of the "Sign in with Apple"
button. This means we are now using black as foreground and white as
background color.
- Add the "Sign in with Apple" capability to the macOS version, to
handle the sign in within the app as it is done for the iOS version.
- Add description in the "CreateDeck" widget, because it was confusing
for the review and they were thinking that they had to provide their
name.
- Adjust "Release" section in contributing guide.
- Disable "X" datasource, since it is not working after the latest API
adjustments.
- Update "version" key and "msix_config.msix_version" key in
"pubspec.yaml" file.
- Change user in "AddSourceReddit" widget help text.
- Enable macOS App Sandbox.
- Adjust logo for Windows version.
