WidgetBridge

Typed, atomic handoff of data and images from a Kotlin Multiplatform app to its home-screen widgets: Jetpack Glance on Android, WidgetKit on iOS. The widget extension never links Kotlin.

Start here

1. Setup, Android: a Glance receiver and the read-inside-the-composition rule.
2. Setup, iOS: the App Group on both targets and the Swift package.
3. The quickstart on the README, then when to publish.

Guides

• How it works: generations, the pointer, the redraw request.
• Feed format and reader rules: the on-disk contract both readers implement.
• When to publish: debounce, foreground, and the pre-encode fingerprint pattern.
• Recipes: Lock Screen family, several widgets from one feed, localized payloads, a word-of-the-day timeline.
• FAQ and known issues.
• Stability and versions.

Reference

• API reference (Dokka), binary API tracked in widgetbridge/api.
