Widgets

ZSMigrateTipView

A native iOS widget that encourages users with active StoreKit subscriptions to migrate to web billing for savings. The view is completely autonomous and self-contained:

• Automatically shows only when applicable (user has StoreKit subscription but no web entitlement)
• Handles its own checkout flow internally
• Manages expansion/collapse animations
• Dismisses itself when complete or cancelled
• Returns empty view on Android or when not applicable

Usage:

ZSMigrateTipView(
  backgroundColor: Theme.of(context).colorScheme.surface,
  userId: 'user123',
)

Properties:

• backgroundColor - Background color for the tip view
• userId - Your app's user identifier

Note: This widget requires no callbacks or state management. It's a "set it and forget it" component that handles everything internally.

How It Works

This plugin is a thin Dart wrapper around the native ZeroSettleKit (iOS) and ZeroSettle-Android SDKs. On iOS, the plugin pulls ZeroSettleKit via Swift Package Manager. On Android, it declares an exact-pinned Maven coord (io.zerosettle:zerosettle-android:1.0.0 + …-ui:1.0.0); adopter apps resolve from Maven Central at build time.

Local development against an in-tree Android SDK

For plugin development against an unpublished ZeroSettle-Android checkout, use mavenLocal() publishing — the conventional Android multi-repo workflow.

From the ZeroSettle-Android checkout, after every SDK source change:

cd /path/to/ZeroSettle-Android
./gradlew :core:publishToMavenLocal :ui:publishToMavenLocal

This produces ~/.m2/repository/io/zerosettle/zerosettle-android/1.0.0/... and …-ui/1.0.0/.... The plugin's android/build.gradle already lists mavenLocal() first in its repositories, so the in-tree build will pick up the locally-published artifacts.

When the SDK version on main differs from the published Maven Central version, the plugin's pinned coord (1.0.0) needs a matching local publish for resolution to succeed; otherwise builds fall through to Maven Central as normal.

Why not composite-build / includeBuild? Composite-build couples the AGP version across all repos (you'd need plugin / example / SDK all on the same AGP line). The plugin and the SDK ship on independent release cadences; mavenLocal keeps them decoupled. Production resolution is also identical to dev resolution (both go through the Maven coord), reducing "works in dev, fails in prod" surprises.
