Getting started

Requirements and installation

Requires Dart 3.4 or later (before Dart 4).

Add the package to your Dart project:

dart pub add appium_driver

Server URL

The default server URL is http://127.0.0.1:4723/, matching Appium 2 and 3. For a server configured with another base path, pass its URL explicitly, including the trailing slash (for example, http://127.0.0.1:4723/wd/hub/).

Examples and session cleanup

See the example and functional tests for usage.

Call driver.quit() to end the session and close the client's connection, or driver.quit(closeSession: false) to disconnect while keeping the server session.

Appium compatibility

Protocol

The client uses the W3C protocol (WebDriverSpec.W3c or Auto). WebDriverSpec.JsonWire is unsupported and throws UnsupportedError.

Session discovery and logs

Session discovery and log retrieval use /appium/sessions, /se/log/types, and /se/log, with fallback to the older endpoints only when the server reports an unknown command or method. Appium 3 session discovery requires starting the server with --allow-insecure='*:session_discovery'.

Legacy device endpoints

Other legacy device endpoints depend on the installed Appium driver and version. Appium 3 removed several of these endpoints; use the corresponding driver mobile: execute methods where needed, for example:

await driver.execute('mobile: pressKey', [{'keycode': 66}]);

See the Appium 3 endpoint migration guide.

API notes and migration

Nullable attributes

Element attribute lookups return String?: an absent attribute is null, distinct from the literal string 'null'.

Android keycode modifiers

pressKeycodeWithBitmasks and longPressKeycodeWithBitmasks accept integer metastate and flags bitmasks:

await driver.device.pressKeycodeWithBitmasks(66, metastate: 1 | 2, flags: 32);

The original pressKeycode and longPressKeycode methods still accept lists, but are deprecated. Existing calls remain valid:

await driver.device.pressKeycode(66, metastate: [1, 2], flags: [32]);

List entries are combined with bitwise OR before sending. Empty lists produce zero, and omitted or null arguments are not sent.

Supported commands

WebDriver commands

See the webdriver.dart API reference.

Some W3C actions
- https://pub.flutter-io.cn/documentation/webdriver/latest/webdriver.io/Mouse-class.html
- https://github.com/google/webdriver.dart/blob/6d7943ef098d3c938b1f4da5a8590fe827f3dd80/lib/src/handler/w3c/mouse.dart

Appium actions

The client supports W3C commands such as finding elements, clicking, and sending keys. The list below tracks client implementations; availability on the server depends on the Appium version and installed driver. See Appium compatibility for limitations.

Not planned or low priority

Most of the commands below are available via extension commands, starting with mobile: in https://github.com/appium/appium-uiautomator2-driver, for example. Thus, they would not be implemented.
