Pull request overview
This PR introduces a cross-platform “user messaging” feature (Radiance-backed durable messages) to Lantern, including a Flutter presentation host (snackbar), a repository/controller layer, and native (Android/iOS/macOS + Go core/FFI) bridging to pull/refresh/acknowledge messages while keeping localized campaign copy out of logs/events.
Changes:
- Added Flutter user-message domain model, controller/repository, route-safety observer, and a
UserMessageHostthat presents durable messages viaSnackBarand acknowledges only after visible. - Implemented native + FFI bridges for
currentUserMessage,refreshUserMessages, andacknowledgeUserMessageacross Dart platform/FFI services, Go core, and Android/iOS/macOS handlers. - Added extensive unit/widget/integration tests and passed app version into Radiance initialization via env overrides.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
_presentation is never cleared when the message expires between the claim and the timer setup.
Line 159 reads the clock again after claimForPresentation already accepted the message. If expiresAt falls between those two clock reads, untilExpiration <= Duration.zero and line 161 calls _expireBeforePresentation, then line 162 returns. That early return skips the feature.closed.then registration, so _presentation keeps the stale value.
After that, _scheduleAttempt takes the presentation != null branch at line 100 and _attemptPresentation returns at line 121. The host then never presents another message for the rest of the session.
Register the closed handler before the expiration check. _expireBeforePresentation calls feature.close(), so the handler runs and clears _presentation.

- final untilExpiration = message.expiresAt.difference(_now);
- if (untilExpiration <= Duration.zero) {
- _expireBeforePresentation(presentation);

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Release the semantics handle in a tear-down.
Line 337 calls semantics.dispose() at the end of the test body. If any expect between lines 333 and 336 fails, that line never runs and the semantics handle stays open. Later tests in this file then run with semantics enabled, which can produce failures that hide the original one. The other resources in this test already use addTearDown.
💚 Proposed fix
- final semantics = tester.ensureSemantics();
+ final semantics = tester.ensureSemantics();
+ addTearDown(semantics.dispose);Then remove the trailing call:
expect(tester.takeException(), isNull);
- semantics.dispose();
