adb_kit

A typed Dart wrapper around the Android Debug Bridge (adb). Built so Flutter desktop apps, CLI tools, or test harnesses can drive any feature of adb without dropping into shell-string concatenation.

Used by the adb_vision example Flutter desktop app — a full GUI for ADB.

Features

• Process runner — AdbRunner spawns adb once per call, streams stdout/stderr line-by-line, supports cancellation, timeouts, and per-device -s <serial> binding. Every invocation is observable through an AdbObserver callback.
• Device management — adb devices -l parsing, polling stream, connect, disconnect, pair, tcpip, wait-for-*, reconnect, root/unroot, remount, sideload.
• Connection — forward / reverse lists and edits, mdns.
• Packages — pm list packages with the full flag set, install / install-multiple / uninstall with typed InstallOptions, clear, enable/disable/hide/suspend, grant/revoke, AOT compile.
• Activity manager — am start / broadcast / startservice driven by a typed IntentSpec, plus force-stop, kill, kill-all, user switching, current focused activity/window, stack/task lists.
• Input injection — typed InputService with tap, swipe, dragAndDrop, text, keyEvent, motionEvent, plus a CoordinateMapper that translates widget-space coordinates to device-space respecting orientation. KEYCODE_* constants on KeyCode.
• Screen — screencap (single PNG and continuous stream), screenrecord with all flags, save-to-file helpers. Mirror loop is the fallback backend for live mirroring; an scrcpy backend is left as an integration point because it requires a native H.264 decoder.
• Displays — dumpsys display parser, secondary-display simulation via overlay_display_devices, wm size/wm density/wm rotation.
• Logcat — streaming tail with LogcatFilter (buffers, priority, tags, format, pid, uid), parsed LogLine records, snapshot, clear, buffer-size APIs.
• Files — ls -la parser, push / pull, mkdir, rm, mv, cp, chmod, chown, cat, find, df, du.
• Shell — one-shot exec with timeouts and an interactive shell handle for PTY-style use.
• Settings — settings list/get/put/delete for system|secure|global plus convenience presets (disable animations, dark mode, force RTL).
• Props — getprop (parsed map), setprop.
• Network — svc wifi/data/bluetooth/nfc, cmd connectivity airplane-mode, ip addr/route, ping, netstat.
• Power — typed reboot targets (normal / bootloader / recovery / sideload / fastboot), screen on/off, wake, deviceidle.
• Dumpsys — typed BatteryInfo plus convenience wrappers for window/activity/meminfo/cpuinfo/gfxinfo/netstats/connectivity/wifi/telephony/location/notification/input/package/usagestats/thermal/alarm/dropbox.
• Scripts — JSON-serialisable Script model, ScriptRecorder for capturing manual interactions, ScriptPlayer with playback events, speed control, loops, wait_for, assert, and ${var} interpolation.
• Backup / restore — adb backup/adb restore (legacy).

Install

dependencies:
  adb_kit: ^0.1.0

Usage

import 'package:adb_kit/adb_kit.dart';

final adb = AdbKit(adbPath: 'adb', observer: (e) => print(e.runtimeType));

await adb.version();              // throws if adb is not on PATH
final devs = await adb.devices.list();
final serial = devs.first.serial;

// Tap on the screen.
await adb.input.tap(serial, x: 540, y: 1200);

// Stream logcat.
final stream = adb.logcat.tail(serial);
final sub = stream.listen(print);
await Future<void>.delayed(const Duration(seconds: 5));
await sub.cancel();

// Run a JSON script.
const json = '''
{
  "name": "demo",
  "steps": [
    {"type": "tap", "x": 540, "y": 1200, "delay_ms": 0},
    {"type": "wait", "ms": 500},
    {"type": "text", "value": "hello"}
  ]
}''';
await for (final event in adb.scripts.play(serial, Script.decode(json))) {
  print(event);
}

Tests

dart test

The unit tests cover device parsing, package parsing, coordinate mapping, script roundtrip, shell quoting, and intent argument rendering.

Coverage map

The full ADB surface from the ADB Vision spec is implemented as follows:

Out of scope (yet)

• scrcpy H.264 backend — needs a native decoder plugin. Use ScreenService.mirror() (screencap polling) for a portable fallback.
• OCR / view-hierarchy / pixel-RGB asserts — stubbed, expand ScriptPlayer._assert to add more kinds.

❤️ Support this package

adb_kit is maintained as a free, open-source library. The Android platform-tools surface keeps shifting — new pm flags, cmd subcommands, permission model tweaks every release — and keeping this package's typed API in lockstep takes ongoing work. If it's saving your team time on a paid project (test farms, kiosk fleets, QA automation, desktop tooling), please consider sponsoring its maintenance.

Other ways to help, even without money:

• ⭐ Star the GitHub repo — visibility is what brings new contributors.
• 🐛 File issues when an adb command misbehaves — paste the command, the device fingerprint (getprop ro.build.fingerprint), and the package version.
• 🔌 Submit PRs — the example/ ADB Vision app is a good way to add new flows (mirror backends, view-hierarchy inspector, OCR asserts) without touching the core library.
• 🧪 Test on weird devices — vendor-skinned Androids and emulator variants are where the parsers break first; reports help.
