Android app (apps/mobile) with Flutter

apps/mobile is a Matrix client for Android on the famedly Matrix Dart SDK, with vodozemac (compiled from Rust during the build) for end-to-end encryption. It speaks the plain Client-Server API and uses the web client's design tokens, fonts and symbol. - Sign in by server name (.well-known), homeserver address or full user ID; sign up with the dummy and registration token stages. Sessions survive restarts: SQLite in private storage, credentials also in the Keystore, both excluded from backups and device transfers. - Room list with unread and mention counts, invites, search and filters. Timeline with grouping, day separators, notices, history on scroll, links, images and files (authenticated media). Sending text, photos, camera shots and files, with Sending/Sent/Read/Not sent and Retry. Typing, receipts, deleting. New rooms and DMs, encrypted by default; joining by address; room info with members, invite, rename, topic, notification level, leave. - Encryption: one-step setup behind a recovery key, verifying a new session with the recovery key (restoring the backup) or another session, emoji verification of people and sessions, reset. Undecryptable messages say why. Session list with verify and sign out. - Notifications while running, and push through UnifiedPush (no Firebase): the distributor's endpoint becomes an event_id_only pusher, the gateway is discovered, and a push starts the app headless to fetch, decrypt and show the event. Make targets: mobile (release APKs per ABI into bin/), mobile-run, mobile-test. Kotlin incremental compilation is off (Windows, project and pub cache on different drives), and Tink's JVM artifact is excluded in favour of tink-android.

+# Warp for Android
+
+A Matrix client for Android, written in Flutter on the famedly
+[Matrix Dart SDK](https://github.com/famedly/matrix-dart-sdk) with
+[vodozemac](https://github.com/matrix-org/vodozemac) for end-to-end
+encryption. It speaks the plain Client-Server API, so it works against any
+Matrix homeserver, not only Warp. The same code is meant to ship to iOS
+later (PLAN.md §8.5); only Android is built and tested today.
+
+It looks like the [web client](../web/README.md): the same tokens (colours,
+radii), the Outfit and Figtree fonts, the Warp symbol.
+
+## What it does
+
+- Sign in with a password, on a server name (`example.org`, found through
+  `/.well-known/matrix/client`), a homeserver address, or a full user ID
+  alone. Sign up when the server allows it, with a registration token when
+  it asks for one.
+- The session survives restarts: sync state, rooms and keys are in SQLite in
+  the app's private storage, and the access token and cached secrets also
+  in the Android Keystore (`flutter_secure_storage`). They are excluded from
+  cloud backups and device transfers, since a restored copy would be a
+  second session with this one's keys.
+- Room list: unread and mention counts, invites first with Join and
+  Decline, a search, and filters for unread, people and rooms.
+- Timeline: grouped messages, day separators, room events as one-line
+  notices, older history on scroll, links that open in the browser, images
+  (full screen with zoom), files saved where you choose. Media is fetched
+  with the access token (authenticated media, Matrix 1.11).
+- Sending: text (`/me` and the SDK's other commands), photos and videos from
+  the gallery or the camera, any file. A message shows at once as
+  *Sending*, then *Sent*, then *Read* once someone else has read it; a
+  failed one says *Not sent*, with Retry and Delete on a long press.
+- Typing notifications, read receipts, deleting messages, editing shown as
+  *edited*.
+- New rooms (end-to-end encrypted by default, public or not), direct
+  messages (encrypted), joining by address. Room info: members with their
+  role and verification shield, invite, rename, topic, notification level,
+  turning encryption on, leaving.
+- End-to-end encryption, on by default:
+  - *Set up encryption* creates cross-signing keys, secret storage and a key
+    backup in one step, behind a recovery key shown once.
+  - A new session verifies itself with the recovery key (which also
+    restores older messages from the backup) or from another session.
+  - Verifying people and sessions by comparing emoji, from room info, the
+    session list, or an incoming request.
+  - A message this session can't decrypt says why, not just "encrypted".
+  - *Reset encryption* for a lost recovery key.
+- Sessions: every session of the account, which are verified, verify one,
+  sign one out.
+- Notifications while the app runs, one per room, opening the room when
+  tapped, and push notifications through
+  [UnifiedPush](https://unifiedpush.org) (below).
+- Settings: display name, avatar, theme (system, light, dark).
+
+**Not yet:** replies, reactions, threads, spaces, voice and video calls,
+QR-code verification, Simplified Sliding Sync (the SDK has no client for
+it, so the app uses `/sync`), a per-message trust shield like the web
+client's.
+
+## Push notifications
+
+Warp doesn't use Firebase. Push goes through UnifiedPush: the user installs
+a *distributor* app, such as [ntfy](https://ntfy.sh), and turns on *Push
+notifications* in Settings. The distributor gives the app an endpoint,
+which becomes a Matrix pusher on the homeserver. When something notifies,
+the homeserver posts to the distributor's Matrix gateway, the distributor
+wakes the app, and the app fetches the event, decrypts it if it can, and
+shows it.
+
+- Pushes are `event_id_only`: the gateway and the distributor never see
+  message content, in encrypted rooms or not.
+- The gateway is found with UnifiedPush's discovery
+  (`GET <endpoint origin>/_matrix/push/v1/notify`; ntfy has one). A
+  distributor without one goes through UnifiedPush's public gateway,
+  `matrix.gateway.unifiedpush.org`.
+- The homeserver needs `push.enabled` (the default); see
+  [docs/push.md](../../docs/push.md). It accepts any gateway URL with the
+  path `/_matrix/push/v1/notify`.
+- Without a distributor the app is still notified, but only while Android
+  keeps it running.
+
+## Build and run
+
+You need:
+
+- Flutter 3.44 or later (Dart 3.12).
+- The Android SDK with an NDK and CMake (Android Studio installs them).
+- Rust, with the Android targets: vodozemac is compiled from source during
+  the build.
+
+  ```bash
+  rustup target add aarch64-linux-android armv7-linux-androideabi x86_64-linux-android i686-linux-android
+  ```
+
+Then:
+
+| Command | What |
+|---|---|
+| `make mobile` | release APKs, one per ABI, to `bin/warp-android-<abi>.apk` |
+| `make mobile-run` | run on a connected phone or emulator (`ARGS=--release` for a release build) |
+| `make mobile-test` | `flutter analyze` and the unit tests |
+
+The first build compiles the Rust crate and takes a few minutes; later
+builds reuse it.
+
+Release builds are signed with the key in `android/key.properties`
+(`storeFile`, `storePassword`, `keyAlias`, `keyPassword`; not committed).
+Without that file they are signed with the debug key, which is fine for
+trying a release build and not for distributing one.
+
+### Against a local homeserver
+
+Debug builds may use plain HTTP, release builds only HTTPS. From the
+emulator, the host machine is `10.0.2.2`:
+
+```bash
+WARP_SERVER_NAME=dev.local WARP_PRIVATE_KEY=./keys/dev.key ./bin/warp generate-keys
+WARP_SERVER_NAME=dev.local WARP_PRIVATE_KEY=./keys/dev.key WARP_REGISTRATION_ENABLED=true ./bin/warp serve
+```
+
+and sign up on the server `http://10.0.2.2:8008`.
+
+### Windows notes
+
+- `android/gradle.properties` turns off Kotlin's incremental compilation:
+  with the project and the pub cache on different drives, plugins fail to
+  compile with "different roots".
+- `flutter test` builds the native code of every dependency for the host,
+  including `webcrypto` (pulled in by UnifiedPush's Linux support). Its
+  build needs CMake 3.13 or later; if Visual Studio's developer environment
+  puts an older CMake first (Visual Studio 2017 ships 3.12), the build fails
+  with "does not appear to contain CMakeLists.txt". Android builds use the
+  Android SDK's CMake and are not affected.
+
+## Layout
+
+| Path | What |
+|---|---|
+| `lib/main.dart` | start-up: notifications, the client, push; a push alone starts the app without UI (`--unifiedpush-bg`) |
+| `lib/app.dart` | the app shell: signed in or not, prompts the SDK raises (password, verification requests), opening rooms from notifications |
+| `lib/matrix/` | everything around the SDK: the client and homeserver discovery (`client.dart`), the timeline projection, media, encryption setup, notifications, push |
+| `lib/screens/` | sign-in, sign-up, room list, room, room info, settings, encryption, sessions |
+| `lib/widgets/` | message bubbles, avatars, new chat, verification, password prompts |
+| `lib/theme.dart` | the design tokens as a Flutter theme |
+| `test/` | the timeline projection, formatting |
+| `assets/` | the brand fonts (as TTF: Flutter can't load woff2) and the symbol |
+| `tool/icons/` | launcher icon sources; `dart run flutter_launcher_icons` regenerates the icons |
+
+The SDK's objects change in place, as matrix-js-sdk's do in the web client.
+Screens watch a counter bumped on every sync (`syncProvider` in
+`lib/state.dart`) and read the client again.
