I am trying to locate an element on a website and get all of the elements. For that, I use Selenide/Selenium. The element what I am looking for is not locatable by one class, so for that I am trying to locate an element with two class (parent and child). With only Selenide, I can easily locate an element using:

SelenideElement basketIcon = $(By.className("buttons")).$(byClassName("btn-cart"))

this will give me one element for sure. But how can I locate an array of an elements? List productName1 = WebDriverRunner.getWebDriver().findElements(By.className("")); but it is not working, also I've tried so: List productName = WebDriverRunner.getWebDriver().findElements(By.className("buttons")); but here how can I add another class to locate an element? $(byClassName("btn-cart"))? Or is there another method to do that?

I've also tried using ElementsCollection elements = WebDriverRunner.getWebDriver().findElements(By.className("")); but it is not working...

This is what I got from the dev tools as outerHTML for element containing the after pseudo element. i even can't see it there and it is just similar to other elements there who doesn't contain pseudo elements.

I have an app that and I'm attempting to use 3 packages: responsive_framework, flutter_easyloading, and one_context. Problem is, I can't figure out how to nest them correctly since they all must be called from the MaterialApps builder. I know they have to be nested like so: Responsive_framework>>, but I'm having trouble finding the right combination utilizing their initialization methods.
