Getting 'No gulpfile' found exception when installing appium dependencies. about appium-flutter-driver

[shibupanda]

@ahashmi24 I don't think now patch version is required as Appium 1.16.0 support Appium flutter driver beta.

Please update the flutter driver dependency to latest in package.json and do npm install.

I tried the same what suggested. However, I am still getting same issue:

[email protected] prepare /usr/local/lib/node_modules/appium
gulp prepublish

[22:50:23] No gulpfile found
npm ERR! code ELIFECYCLE
npm ERR! errno 1

npm ERR! Failed at the [email protected] prepare script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

is it possible to push these fixes to appium beta?

@ahashmi24 are you able to start Appium 1.16.0 successfully even after getting above error. If yes then please try to execute the script and check once.

@shibupanda
I have updated appium-flutter-driver version manual by below command:
npm install -g appium-flutter-driver

Now, it is showing :

Ahmers-MacBook-Pro:~ vikasvipul$ npm ls -g appium-flutter-driver
/usr/local/lib

However, the "waitFor" flutter command behaves as previously.

@ahashmi24 could you please share complete Appium logs using gist.

[ahashmi24]

@shibupanda
Please find the gist for the same:
https://gist.github.com/ahashmi24/788098b5ee41bb8cba9e3640c2fc0f91

Code snippet:
driver.context("FLUTTER");
FlutterElement buttonToOpenCalendar = find.byValueKey("button"); // intentionally I used incorrect value key
driver.executeScript("flutter:waitFor", buttonToOpenCalendar);

@ahashmi24 looks like it's a existing driver not the latest one. Please install correctly.
One suggestion it may work for you. Please delete the existing appium-flutter-driver from node modules and please install the latest driver in the same node modules directory without -g.

@truongsinh any idea when the flutter driver latest version will come up with appium bundle.

@shibupanda @ahashmi24
Yes, firstly, 1.16.0 of appium already include appium-flutter-driver, so we no longer need the patch version. I will update README.

Can you try remove and re-install appium? This seems to be the error from appium package.

@shibupanda @truongsinh
I have tried installing appium beta version (npm install -g appium@beta) and could see the latest appium-flutter-driver version which is coming with appium beta bundle.

Ahmers-MacBook-Pro:~ vikasvipul$ appium -v
1.16.0-beta.3
Ahmers-MacBook-Pro:~ vikasvipul$ npm ls -g appium-flutter-driver
/usr/local/lib

However, waitFor command still stuck when an element is not present on the screen or passing an invalid locator.

Hi @ahashmi24
We have already updated in README and in nodejs example that from now onward there is one more argument need to pass in wait commands. Needs to be added in other examples as well.

Could you please try below code for java.
driver.executeScript("flutter:waitFor", find.text("I can enter text"), new HashMap<String, Object>() {{
put("durationMilliseconds", 100);
}});

[ahashmi24]

@shibupanda
It's throwing an exception "org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: durationMilliseconds is not a valid options (WARNING: The server did not provide any stacktrace information)"

After adding below code snippet:

driver.executeScript("flutter:waitFor", find.byValueKey("button"), new HashMap<String, Object>(){{
put("durationMilliseconds", 100);}});

@shibupanda

I got it, below syntax is working fine for me:

driver.executeScript("flutter:waitFor", find.byValueKey("button"), 1);

Hence, closing this issue.
