I was hoping someone could help me figure this out, i'm a newbie when it comes to coding.

I've made a form and a background in two seperate files. What i'm trying to achieve is:

1. Merge both files, wherein the form should be on the middle-right side of the screen and I want the background to stay like it is, it should keep changing both the images and background colour.
2. In the form, my scrollbar is going out of the div which has a border-radius, I want it to stay inside.
3. In the form, if you look at the dropdown menu, the bottom arrow isn't properly aligned, how can I move it towards it's left so it's visible properly.

I've tried a few solutions already, but either I mess up the background or the form's alignment changes. Please have a look at the following code for both the files and hopefully help a brother out.

I've also attached their Codepen links: (i) For the background: (ii) For the form:

Thanks in advance. I have a state array as below.

I need to add an item to state array, I came across that we need not do state mutation. How do i set state with prevState.

I am learning about carousel in flutter. I want to give the carousel image the full screen width. But the width is automatically taken by the carousel itself. Is there any way to give the image the full screen width inside carousel? Here I have used both carousel_pro and carousel_slider, neither works as I expected. Please help.

I have this API: https://newsapi.org/v2/everything?q=supercars&apiKey=[MyApiKey]

I'd like to create a view that displays them with some information. I have to iterate on the articles array.

I'd like to replicate the api's info in my views tag. How can I do that? I can access the single info, but can't replicate all the news. With this syntax only the "Lamborgini Sian" news gets shown.

I am trying to 1st divide up four-letter words based upon the last two letters of the word (suffix) and 2nd count up how many words I have for each of these endings.

I have a list containing 3,164 words called filtered and I have sorted them by their suffixes, which doesn't seem much of a help.

(I want to create a dictionary that takes the suffix as a key and the words as a list but I don't know where to begin!) It would be something like:

OUTPUT:

dic = {'ab': ['Ahab', 'Arab', 'Saab, ...]; 'al': ['Aral', 'Baal', ...]}

and so on. Would that be possible?

Have anyone idea what cause this error? It occur when I try getJSONArray from server output e.g.:

output:

{"iActualJoinRequests":"4","jaPassengers":"[{\"id\":\"98747406\",\"name\":\"adam\",\"surname\":\"hfdd\",\"age\":\"2\",\"latitude\":\"54.2113448\",\"longitude\":\"16.1876282\",\"origin\":\"koszalin\",\"destination\":\"sian\u00f3w\",\"ride_id\":\"262243421\",\"date\":\"2017-05-25 18:13:00\"}]"}

I want to join two data sources, orders and customers:
