feat(ui): add onReactionLongPress reporting the long-pressed reaction - #2903
Merged
Conversation
Adds a per-reaction long-press callback to StreamMessageItem and StreamMessageListView, reporting the message's BuildContext and a ReactionLongPressDetails so apps can open a reactions sheet. Left null, the chips register no long-press gesture, so the message's own long-press handling (the actions modal) keeps working as before. Points stream_core_flutter at a local path dep for the matching core change; swap back to a git ref before merging. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The chips sit inside the message row's own long-press InkWell, so both recognizers compete. Assert the chip wins when onReactionLongPress is set, and that the message long press still fires when it is not. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Swaps the local path dep for the commit ref on the core branch so CI can resolve it. Re-point at a merged SHA once GetStream/stream-core-flutter#153 lands. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The chips now always claim the long press and open the detail sheet pre-filtered to that reaction, rather than falling through to the message actions modal. Tap gets the same pre-filtering. Rewrites the long-press tests around the new contract and documents the behaviour change in the changelog. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

pre-filtered only for chips mapping to a single reaction; clustered or overflow

Pre-filtering only applies to chips mapping to a single reaction; clustered and overflow chips report null and open unfiltered. Also disambiguates that the chips claiming the long press is what is unconditional, not the sheet. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
GetStream/stream-core-flutter#153 landed on main as 4b7ed86, so the pin moves off the PR branch commit. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The release warning was lost when the dependency went back to a pub constraint; it matters more now that the pin is a git ref again. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Adds

⚠️ Changedchangelog entries. The rationale: a reaction chip's gestures should be about that reaction, not about the message — long-pressing a reaction to get Reply / Edit / Delete reads wrong, and no major chat client does it.Testing
