Deprecate the unflag APIs since the backend endpoint is no longer supported by andremion · Pull Request #6661 · GetStream/stream-chat-android

andremion · 2026-08-25T15:46:22Z

Goal

The backend endpoint POST /moderation/unflag is deprecated and is a no-op. The SDK still exposes public APIs that call it, so an integrator can call something that silently does nothing.

This PR marks those APIs as deprecated. The removal happens in the next major version.

Resolves AND-1448

Implementation

Added @Deprecated (WARNING level) to the public APIs that reach the endpoint:

ChatClient.unflagUser and ChatClient.unflagMessage
MessageListController.unflagUser and MessageListController.ErrorEvent.UnflagUserError
Compose MessageListViewModel.unflagUser
XML MessageListViewModel.Event.UnflagUser

Added @Suppress("DEPRECATION") where the SDK itself still routes through them, so the build stays free of new warnings: MessageListController.unflagUser, Compose MessageListViewModel.unflagUser, XML MessageListViewModel.onEvent, the errorEventHandler in MessageListView, and ChatClientModerationApiTests.

ChatApi, MoshiChatApi and ModerationApi are internal, so they are left as they are. They get removed together with the public APIs.

No behaviour changes. The .api dumps are unchanged, since the validator does not record annotations.

Testing

./gradlew spotlessApply apiDump (no .api changes)
./gradlew detekt
./gradlew :stream-chat-android-client:testDebugUnitTest --tests '*ChatClientModerationApiTests*' --tests '*MoshiChatApiTest*'

Summary by CodeRabbit

Bug Fixes
- Clarified that unflagging users and messages is no longer supported by the backend.
- Existing unflag actions remain available but have no effect.
Deprecations
- Added deprecation warnings across moderation and message-list APIs.
- Unflagging functionality is planned for removal in the next major release.

…oint The backend no longer supports un-flagging, so these calls do nothing. Mark the public APIs as deprecated and suppress the warning at the internal call sites. They get removed in the next major version.

Walkthrough

The change deprecates client, Compose, and UI unflag APIs and related events because backend un-flagging is unsupported. Existing implementations remain available, while internal consumers and moderation tests suppress deprecation warnings.

Changes

Unflag API deprecation

Layer / File(s)	Summary
Client moderation API deprecations `stream-chat-android-client/.../ChatClient.kt`, `stream-chat-android-client/.../ChatClientModerationApiTests.kt`	`unflagUser` and `unflagMessage` now include deprecation warnings. Moderation API tests suppress these warnings.
Compose and common UI deprecations `stream-chat-android-compose/.../MessageListViewModel.kt`, `stream-chat-android-ui-common/.../MessageListController.kt`	Compose and common UI unflag methods and related error events now include deprecation warnings.
UI deprecation handling `stream-chat-android-ui-components/.../MessageListView.kt`, `stream-chat-android-ui-components/.../MessageListViewModel.kt`	UI event handling suppresses warnings for deprecated unflag events and error events.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to 024d3

This change marks unsupported unflag APIs for removal in a future major release without changing current behavior. No actionable merge-blocking risk remains beyond normal checks and review.

Poem

I’m a rabbit with a warning to share,
Unflag paths now signal, “handle with care.”
The calls still remain, though their future is brief,
Tests hush the warnings and hop past the grief,
While UI events mark the old trail bare.

Explanation

The description clearly explains the goal, implementation, affected APIs, expected behavior, and testing. It omits the UI changes, contributor checklist, reviewer checklist, and GIF template sections, but these omissions are non-critical for this non-visual API deprecation.
