fdb 1.3.0

Flutter Debug Bridge - CLI for AI agents to interact with running Flutter apps on device. Launch, reload, screenshot, inspect widget tree, filter logs.

1.3.0

New commands

• fdb syslog — streams native system logs (iOS Console / Android logcat) for the running app
• fdb native-tap — performs a native in-process tap; also available as fdb tap --at x,y for absolute coordinate targeting

Improvements

• fdb describe now surfaces off-screen children of GridView and ListView that were previously hidden
• App death is now detected and surfaces an APP_DIED error immediately instead of hanging
• .fdb/ state directory is now auto-located by walking up the directory tree, so fdb commands work from any subdirectory of the project
• fdb status returns RUNNING=true when a launch was interrupted but the app is still alive via VM URI fallback
• fdb.app_pid is now stored separately from fdb.pid for accurate app liveness detection

Fixes

• Session directory walk-up no longer escapes to a parent .fdb/ that has no vm_uri.txt when the local PID is stale
• fdb status VM URI fallback works correctly when launch is interrupted

1.2.1

Fixes

• fdb logs now keeps recent VM-service log lines readable through unexpected app crashes by running the log collector as a real entrypoint with serialized flushes

1.2.0

New commands

• fdb doctor - pre-flight health checks for the app process, VM service, fdb_helper, platform tools, and stored device state
• fdb double-tap - double-tap widgets by selector or absolute coordinates
• fdb scroll-to - scroll until a target widget becomes visible, including lazy lists
• fdb wait - wait for widget and route presence or absence without shell polling loops

Improvements

• fdb tap and fdb longpress now support absolute coordinate targeting via --at x,y
• Reload and restart completion now use VM lifecycle events for more reliable detection, including macOS reload handling
• Test automation gained a stricter verify pipeline plus more robust deep-link and double-tap smoke coverage

Fixes

• Android test app now registers the fdbtest:// URL scheme so deep-link smoke tests exercise the real Android flow

1.1.7

New

• fdb screenshot now supports all platforms: macOS (screencapture), Linux X11 (xdotool+import), physical iOS / Windows / Linux Wayland (via fdb_helper VM extension), and web (Chrome DevTools Protocol)
• fdb_helper: new ext.fdb.screenshot VM extension — renders the Flutter surface to PNG and returns base64; used as fallback on platforms with no native capture CLI
• Screenshots are automatically downscaled so the longest side fits within 1200px (preserving aspect ratio), using the pure-Dart image package; pass --full to get native resolution

Fixes

• Screenshot: fdb launch now writes .fdb/platform.txt so screenshot dispatches to the correct backend without probing live tools at capture time
• Screenshot: Android and iOS simulator now targeted by explicit device ID (no more booted heuristic that breaks with multiple simulators)
• devices.dart: safe cast for emulator field (as bool? ?? false) to avoid crash on unexpected flutter devices output
• extractDevicesJson deduplicated into process_utils.dart (was copied in both launch.dart and devices.dart)
• Fix CI release: fdb_helper/CHANGELOG.md missing 1.1.6 entry caused GitHub release to not be created despite pub.dev publish succeeding

1.1.6

Fixes

• SKILL.md state files section corrected: paths are <project>/.fdb/ (not /tmp/) since 1.1.0
• SKILL.md screenshot default path corrected to <project>/.fdb/screenshot.png
• doc/README.agents.md screenshot default path corrected to <project>/.fdb/screenshot.png

Improvements

• README: updated Flutter MCP server description to accurately reflect its current capabilities (runtime introspection, not just static analysis)
• README: comparison table "Device interaction" row now enumerates fdb's full interactive command set and correctly characterises the MCP server as read-only
• README: fdb describe command annotated with (requires fdb_helper) in the commands table

1.1.5

Fixes

• Fix CI publish: fdb 1.1.4 was published but fdb_helper was not due to missing CHANGELOG entry

1.1.4

Improvements

• Renamed skill from interacting-with-flutter-apps to using-fdb for better discoverability on skills.sh

1.1.3

Improvements

• fdb_helper is now published to pub.dev — add it as fdb_helper: ^1.1.3 instead of a git path reference

1.1.2

New commands

• fdb shared-prefs get|get-all|set|remove|clear — read/write/clear SharedPreferences from the CLI via a VM service extension in fdb_helper

Fixes

• fdb deeplink now uses the session device ID to detect platform instead of probing all connected devices — fixes misrouting to Android when both Android and iOS are connected but the session is on iOS

Improvements

• Smoke test extended with test:clean and test:shared-prefs tasks covering all sub-commands

1.1.1

Improvements

• fdb_helper install instructions now reference pub.dev (fdb_helper: ^X.Y.Z) instead of a git path reference
• Releasing skill updated to track all 9 version-bearing files

1.1.0

Fixes

• Fix developer.log() output not appearing in fdb logs — flutter run never forwards developer.log() to stdout; a background log collector now subscribes to the VM service Logging stream and appends events directly to the log file

Improvements

• Session state moved from /tmp/fdb_*.txt to <project>/.fdb/ — multiple projects can run simultaneously without interfering with each other
• .fdb/ is automatically added to the project's .gitignore on first launch
• FVM support: launch auto-detects .fvm/flutter_sdk/bin/flutter; override with --flutter-sdk <path>
• --project flag on launch is now optional — defaults to CWD (agents running from the project directory need not pass it)
• Log collector self-cleans on SIGTERM, SIGINT, and when flutter run exits

1.0.1

Fixes

• Fix dartdoc angle bracket warnings in describe.dart and vm_service.dart
• Fix deeplink smoke test — register fdbtest:// URL scheme in test app Info.plist
• Fix back smoke test — restart app to reset UI state before navigation test

Improvements

• Add example/example.md for pub.dev Example tab
• Replace mermaid code block with pre-rendered SVG diagram (renders on pub.dev)
• Add dart pub global activate fdb install option to README
• Add release skill and CI publish workflow

1.0.0

New commands

• fdb back — navigate back via Navigator.maybePop(), handles dialogs and root detection
• fdb longpress — long-press widgets, reuses tap infrastructure with configurable duration
• fdb swipe — swipe gestures for PageView/Dismissible with widget targeting and smart defaults
• fdb describe — compact screen snapshot with interactive element refs (@1, @2...) for agent navigation
• fdb devices — list connected devices
• fdb deeplink — open deep link URLs on device
• fdb skill — print SKILL.md for AI agent consumption

Describe command

• Shows only hittable, topmost-layer widgets (filters obscured/background route elements)
• Gesture info on GestureDetector/InkWell: (tap), (tap,horizontalDrag), (tap,longPress)
• Extracts text from all children, tooltips, and icon semantic labels
• Filters framework widgets and Unicode PUA icon codepoints
• Ref-based tapping: fdb tap @3 taps the 3rd interactive element from last describe
• Shows deepest route name and Scaffold title

Fixes

• Error propagation: specific error messages instead of "Server error"
• --text tap: walks to hittable ancestor when Text widget itself isn't in hit-test path
• --index ordering: user widgets before framework widgets (Overlay, IndexedStack, _Theater)
• --key tap: ancestor walk for KeyMatcher/TypeMatcher, not just TextMatcher
• --help / -h: prints to stdout with exit 0, no "ERROR:" prefix
• Swipe velocity: process-relative Stopwatch timestamps for VelocityTracker fling detection
• Screenshot: defaults to 1x logical resolution (~180KB vs ~1MB), --full for native
• Screenshot: supports --output=path equals syntax, fixes Android shell escaping
• Skill command: resolves SKILL.md via package URI for global installs

0.1.0

• Initial release
• CLI commands: launch, status, reload, restart, kill, logs, tree, screenshot, select, selected, tap, input, scroll
• fdb_helper package for Flutter app integration
