Appium Flutter Driver can't detect the port of Dart VM Service, so a Session can't be started properly

[BelalNayzak]

Description

I'm trying to establish a connection (session) between my Flutter App and Appium server but the Appium Flutter Driver always tries to listen on a different port from the correct port that is shown in the Flutter logs when I start the app, so the session fails!

---

Steps to Reproduce

1. Clean Slate (Kill All Old Processes):
Ensure no old processes are running that could interfere. Open a terminal and run:
killall -9 dart flutter node appium || true

2. Start Emulator/Device
Make sure your Android emulator is running and unlocked. Verify it's connected with:
adb devices

3. Start the Flutter App
In a new terminal, navigate to the project root and run the app with service auth codes disabled:
flutter run --debug --disable-service-auth-codes

4. Find the Dart VM Service URL
Wait until the app launched and check the output logs the and find the Dart VM Service URL. It's like that...
A Dart VM Service on sdk gphone64 arm64 is available at: http://127.0.0.1:60693/
Leave this terminal running.

5. Start the Appium Server
appium
Then wait until you see the log message [Appium] Appium REST http interface listener started on http://0.0.0.0:4723.

6. Activate Python Environment and Run Tests
In a final terminal, navigate to the project root, activate the virtual environment, and run the tests:

// Navigate to the project root first
cd /path/to/appium_testing_poc

// Activate venv
source tests_flutter/venv/bin/activate

// Go to tests directory
cd tests_flutter

// Run the tests
python run_tests.py

---

Expected Behavior

A session between appium server and my app get established properly and the tests get executed.

---

Actual Behavior

All the tests fails since the session is not not established properly. The appium server tries to listen on a different port than the Dart VM Service works on (check the logs below).

In your driver method...

@pytest.fixture(scope="session")
def driver_android():
"""Setup Android driver for testing"""
options = UiAutomator2Options()
options.platform_name = Config.ANDROID_PLATFORM_NAME
options.device_name = Config.ANDROID_DEVICE_NAME
options.app_package = Config.ANDROID_APP_PACKAGE
options.app_activity = Config.ANDROID_APP_ACTIVITY
options.automation_name = "Flutter"
options.no_reset = True
options.max_retry_count = "20"

driver = webdriver.Remote(Config.APPIUM_SERVER_URL, options=options)
driver.implicitly_wait(30)

yield driver

driver.quit()

Use the APK path instead of package name when launching the app for the first time. If you don’t want to reset the application afterward, you can switch to using the package name or bundle ID. I believe the lack of APK path is causing the issue of dart VM not connecting.

[KazuCocoa]

        # Use the fixed port for Flutter VM service
        options.set_capability("appium:flutterServiceUrl", f"ws://127.0.0.1:{Config.FLUTTER_VM_SERVICE_PORT}/ws")

What is this capability? Do you mean appium:observatoryWsUri? https://github.com/appium/appium-flutter-driver?tab=readme-ov-file#capabilities

Also, sharing the adb logcat result would help since the URL depends on adb logcat output.

[BelalNayzak]

@Zubairahmdfaraz with the app path and it works, Thanks!
My another approach is what if need to test with the AppPackage / BundleId, I need to be able to test applications even if I don't have the .apk or .app files of this application.

@KazuCocoa will try with the capability you mentioned and refer to you again, may be it's a missmatch of the capability name, Thanks to noting that.
