how to make scrollView known when hit end list

so i got a problem where my scrollView can infinite scroll until the banner or the container is gone, what i want is when you hit the lest section like number3 you can’t scroll anymore, because i want so the name part doesn’t move the only thing that move is only the chart – end

example of the code:

NewTableScree.tsx:

    const dataDummy = [
    {
        key: 1,
        name: "Tommy",
        chart: "10",
        char2: "20",
        chart3: "30",
        number: "100",
        number2: "2000",
        number3: "2000", 
    },
    {
        key: 2,
        name: "William",
        chart: "10",
        char2: "20",
        chart3: "30",
        number: "100",
        number2: "2000",
        number3: "2000", 
    },
    {
        key: 3,
        name: "Robert",
        chart: "10",
        char2: "20",
        chart3: "30",
        number: "100",

export default NewTabelScreen

if anyone can solved my problem it will be a help Thank you very much.

>Solution :

FlatList has large right margin.

<FlatList
  style={{ 
    width: windowWidth, 
    marginRight: heightPercentageToDP(50) // remove it!
  }}
...

if you remove ‘marginRight’, then it works as expected
