Squash-merge commit. Covers four areas: native video player, chat reliability, multi-tab, and hardening. ## Native video player - Direct HLS playback via `better_native_video_player` (forked from `plug-and-pay/flutter-native-video-player`, patched on `frosty-patches` branch) - Twitch GQL playback token fetching with platform cookie extraction (iOS Swift + Android Kotlin plugins) for authenticated streams - Quality selection (source, 720p, 480p, 360p, 160p, audio-only) persisted per channel - Picture-in-picture: iOS automatic inline PiP, Android auto-PiP on API 31+ guarded against older devices - Latency polling, chat latency sync, stall detection/recovery, startup auto-pause recovery, watchdog timers - **Twitch stitched-ad break detection** (HLS `EXT-X-DATERANGE`) on both platforms, emitting `adBreakChanged` so the host suspends latency/stall recovery and chat sync during ads (program-date-time is unreliable then). Matches `CLASS="twitch-stitched-ad"` / `ID="stitched-ad-"` **and** the `X-TV-TWITCH-AD-*` attribute prefix (the durable signal streamlink/yt-dlp use) - Shared `VideoPlayerInterface` so WebView and native paths are interchangeable via settings toggle - `PlaybackAccessToken` model, `TwitchGqlApi` client ## Chat delay & send reliability - **Optimistic send-finalize**: Twitch acks a sent message with a per-PRIVMSG USERSTATE (not an echo), which it can intermittently drop — more so under a long chat delay. A missing ack no longer shows a false "message may not have been sent" error; the send is finalized optimistically (local echo rendered), and only genuine rejection NOTICEs surface an error. Ack timeout scaled by the chat delay. - **Per-line chat-delay bypass**: control/state lines (USERSTATE/ROOMSTATE/GLOBALUSERSTATE), rejection NOTICEs, the reconnect notice, and untagged server lines bypass the delay so send-acks and PONGs aren't stalled; only displayable chat content is delayed, staying in sync with delayed video. - **Measured chat bottom-bar height**: the message list reflows to the composer's real measured height, fixing the input overlapping messages when a long message expands it (replaces a fixed-constant estimate). - IRC tag parsing handles valueless and escaped tags per the IRCv3 message-tags spec (fixes a recent-messages RangeError on certain tags). ## Chat / multi-tab - Redesigned tab chips: unread dot indicator, chips dim until WebSocket connects - Animated tab options popover replacing `MenuAnchor` (no animation hook in Flutter 3.44) - Simplified `ChatTabs` from `StatefulWidget` to `StatelessWidget` - Focus-current-channel fade bump to 0.55; section-header alpha lifted to match the muted-label tier - `addTab` now calls `setActiveTab` to snapshot outgoing tab's `lastSeenMessageId` — fixes spurious unread dots after adding a tab - `onActivateSourceTab` threaded into `ChatUserModal` so Reply in merged mode switches to the correct source tab's composer ## Bug fixes and hardening - **Reverted the experimental iOS low-latency mode** (5s live-edge join + 1.05x catch-up): AVPlayer can't sustain <~18s on Twitch (declared `TARGETDURATION:6` paces playlist refreshes), and the offset starved the buffer into pause-on-launch. Default join distance restored. - Fork (Android): **cap `BEHIND_LIVE_WINDOW` recovery** so a stream repeatedly falling off the live window can't silently re-prepare forever; emits `error` on exhaustion so the host recovery ladder takes over - Guard all Android `setAutoPipMode` calls with `_autoPipAvailable` — prevents `PlatformException` on Android 8–11; check `_disposed` after `isAutoPipAvailable` await to prevent post-dispose auto-PiP re-enable - Remove `_isInPipMode` guard from `_onPaused` so `_paused` tracks actual state, fixing PiP play/pause toggle getting stuck - Tighten iOS cookie domain check to exact `twitch.tv` / `.twitch.tv` suffix - Invalidate the stored web session token when Twitch rejects it with a 401 (profile card flips back to unlinked; future loads skip the doomed authenticated request), and re-extract the cookie on launch when logged in without a linked session - Send `play_session_id` and `player_backend=mediaplayer` to Usher, matching the web client / streamlink - Fork (iOS): restore program-date-time latency measurement (a prior rev measured distance to the manifest edge, reading ~0s and silently disabling high-latency recovery / chat-delay auto-sync); release platform views on dispose (per-stream view + AVPlayerViewController leak), track the observed AVPlayerItem for KVO removal (sibling-view crash), main-thread seek results, resolve superseded load futures - Fork (Android): clean up method handlers orphaned by PiP-time view disposal (leaked audio-focus listeners), drop the live-offset re-anchoring seekTo on metadata updates (latency creep), restore pre-duck volume, respect user pause in the stall watchdog, resolve superseded load futures - Deep review pass: expire the quality-switch flag so stall recovery isn't disabled for the session, cap latency-driven recovery (clock-skew loop), generation-guard the error overlay, two-strike offline confirmation, controller null-safety on quality switch - Tighten `/me` local-echo match (no longer renders `/meow ...` as an action); clear pending send text on disconnect ## Web / docs - Remove stale Cloudflare Images binding from `wrangler.jsonc` (covered by `images.unoptimized: true`) - Correct `web/AGENTS.md` Cache Components claim (feature not enabled) - Repo and agent config cleanup ## Test plan - [x] `flutter analyze` — clean (frosty + plugin lib) - [x] `flutter test` — 319/319 pass (adds `ChatLatencySync`, `StreamInfoPoller`, video timing invariants, `PlaybackAccessToken`, IRC tag parsing) - [x] Android plugin Kotlin compiles against the bumped fork rev - [ ] Native player plays live streams on iOS and Android - [ ] Quality switching works and persists across channel reopens - [ ] PiP enters/exits correctly; pause/resume toggle in PiP window works - [ ] Audio-only mode does not crash on Android < API 31 - [ ] Sending under a long synced chat delay no longer shows a false "may not have been sent" error - [ ] Long composer text reflows the message list (no input/message overlap) - [ ] Multi-tab: adding a tab does not mark previous tab as unread - [ ] Merged chat: Reply from user modal targets the correct tab's composer 🤖 Generated with [Claude Code](https://claude.com/claude-code)

## Code Opinions
|
|
|
|
- Package imports (`import 'package:frosty/...'`), not relative imports
|
|
- Trailing commas always
|
|
- Single quotes
|
|
- Extract related/grouped logic (state, reactions, actions) into dedicated stores when it improves readability — keep widgets focused on rendering
|
|
|
|
## Infrastructure Checklist
|
|
|
|
When creating new infrastructure (screens, API clients, stores), use exploration findings as a **checklist** — systematically verify each convention is followed before writing code.
|
|
|
|
## Never
|
|
|
|
- Never edit `.g.dart` files directly — always regenerate with `dart run build_runner build`
|
|
|

# Project
|
|
|
|
Flutter mobile app for browsing Twitch on iOS and Android. Uses MobX for state management with code generation.
|
|
|
|
## Commands
|
|
|
|
```bash
|
|
flutter pub get # Install dependencies
|
|
flutter run --dart-define=clientId=ID --dart-define=secret=SECRET # Run with Twitch credentials
|
|
flutter analyze # Static analysis (run after changes)
|
|
flutter test # Run tests (if changes touch testable logic)
|
|
dart run build_runner build # Regenerate .g.dart files (MobX/JSON models)
|
|
dart run build_runner build --delete-conflicting-outputs # Same, but clears stale outputs
|
|
```
|
|
|
|
## Source Structure
|
|
|
|
- `lib/apis/` — API services (all extend `BaseApiClient`)
|
|
- `lib/models/` — Data models (`@JsonSerializable` with `.g.dart` codegen)
|
|
- `lib/screens/{feature}/` — Feature screens with co-located `stores/` subdirectories
|
|
- `lib/stores/` — Global stores only (e.g., `global_assets_store.dart`)
|
|
- `lib/services/` — App-level services
|
|
- `lib/widgets/` — Shared widgets
|
|
- `lib/utils/` — Utility functions
|
|
|
|
## Architecture
|
|
|
|
- Feature stores live in `lib/screens/{feature}/stores/` — don't create new top-level store files (only `lib/stores/` holds global stores)
|
|
- All API services extend `BaseApiClient` (`lib/apis/base_api_client.dart`) — don't create standalone API classes
|
|
- MobX stores use a generated mixin pattern — see `lib/screens/settings/stores/auth_store.dart` for the canonical example
|
|
|
|
## Gotchas
|
|
|
|
- After changing MobX stores or `@JsonSerializable` models, regenerate with `dart run build_runner build`. Never edit `.g.dart` files directly. Commit `.g.dart` files to source control.
|
|
- The secure storage cleanup in `main.dart` looks unnecessary but handles an Android/iOS edge case where secure storage persists after uninstall. Don't remove it.
|
|
|
|
## Testing
|
|
|
|
- `flutter test` runs all tests; `flutter test test/path/to/file.dart` for a single file
|
|
- HTTP mocking: `http_mock_adapter` (`DioAdapter`) — use full URLs in `onGet`/`onPost`
|
|
- General mocking: `mocktail` (no codegen required)
|
|
- Fixtures live in `test/fixtures/` (e.g., `irc_messages.dart`, `api_responses.dart`)
