SwipeCard | 高仿探探、陌陌左右，滑动卡片容器，这个容器是不销毁任何的View，添加几个存在集合，可以循环️的进行展示

I have a swipeable component with an open and close function that I would like to trigger from a child of the component. I don't think using state to do it in this instance would be correct since I want to avoid a re-render while the swipeable component is animating (please correct me if I'm wrong).

I'm using react-native-gesture-handler/swipeable and following their example here

SwipeCard component

I'm new to Google Firebase, React, and Javascript and attempting to make a Tinder Clone. I had trouble with my code and someone on StackOverflow helped me by fixing the errors that popped up in my code, but I'm now stuck figuring out how to store and retrieve (multiple) data from Firebase's database. As far as I can understand, the code creates a query for the collection and then unsub stops the listener? This is the code someone of StackOverflow gave.

This is my first time asking a question on StackOverflow. I am making a school project and I am a beginner at Firebase and JavaScript. I am trying to make a Tinder clone. React is telling me there's an error in this part of my code. At first I had different errors but they were Firebase syntax related and I promptly fixed them but now I don't have a clue on what this error means. My code works on localhost for a split second (I see my application) and then the error appears.

I'm trying to find a solution to my app more than 3 days, but without success.

I need to read the current user e-mail from a SwipeCardView when the user swipe or lick in a button and store it in a variable to be used later. Is there a simple solution to reach this goal?

See my xaml:

I am currently trying to implement a cocoa pod, but when using it I get the error "Cannot call value of non-function type 'SwipeCard'" in the function " func cardStack". It may a silly mistake since I am just learning how to code in swift.

When I create a new fragment in Android Studio by clicking:

and then choosing Kotlin as language for the new fragment, I get following warning that I have to implement two members or make the class abstract. When I make it abstract the program doesn't start, because it can't instanciate the abstract class. When I implement the methods I don't know what I have to put into them and the program doesn't start with the error that they don't override anything:

When I create the Fragment in Java it works, I don't understand it. Here is how I call the fragment from the activity:

Copied java code from diolor/swipecards (GITHUB). Converted it into kotlin with help pf online tools. It had some errors which were corrected but this last one still appears (findViewById) in the OnScroll function.

I have a list of strings that form an item menu created horizontally:

I created a list of item that are scrollable horizontally, and I am trying to render different widgets depending on what button is pressed. The widgets are created in different and independent files. What I need to achieve is to import them widgets depending on what button is pressed. For example, that the widget of "DropDown" is rendered when the button of "DropDown" is pressed on the list. The screen is the following:

Here is the code of the buttons list and where I should import the widgets:
