HI @CU23051955-2 ,

This can be easily achieved with collection and index of the current news item.

Although Power Apps doesn't support gesture/swipe controls for this yet, you can easily add navigation buttons to cycle through the news items while respecting filters. Here's how you can implement it:
Your Scenario:
You have a Gallery that displays filtered news items (from SharePoint).

You have a Detail Screen that shows one selected item.

You want Next and Previous buttons on the Detail Screen to navigate through the gallery-filtered list.

Step 1: Generate a Row Index number for Sharepoint News data source if not done already:
Example :

With(
    {
        prodCountRow: Filter(
            'Sales Data',
            StartsWith(
                'Product Name',
                txtSearchProduct.Value
            )
        )
    },
    ForAll(
        Sequence(CountRows(prodCountRow)),
        Patch(
            Last(
                FirstN(
                    prodCountRow,
                    ThisRecord.Value
                )
            ),
            {ProdRowNumber: Value}
        )
    )
)

Step 2: Track Current Item in a Variable:
On selecting a gallery item:

Set(varCurrentNewsID, ThisItem.ID);
Navigate(DetailScreen, ScreenTransition.Fade)

Step 3: Load Current item in the Detail Screen:
Set the item property of your form or detail controls on the DetailScreen to:

LookUp(colFilteredNews, ID = varCurrentNewsID)

Step 4: Add "Next" and "Previous" Buttons: (Here colFilteredNews is a sample collection storing news data)
OnSelect of Previous :

Set(
    varCurrentIndex,
    LookUp(colFilteredNews, ID = varCurrentNewsID, Index)
);
If(
    varCurrentIndex > 1,
    Set(varCurrentNewsID, LookUp(colFilteredNews, Index = varCurrentIndex - 1, ID))
)

OnSelect of Next:

Set(
    varCurrentIndex,
    LookUp(colFilteredNews, ID = varCurrentNewsID, Index)
);
If(
    varCurrentIndex < CountRows(colFilteredNews),
    Set(varCurrentNewsID, LookUp(colFilteredNews, Index = varCurrentIndex + 1, ID))
)

Bonus Tip:
1. You can style your Next/Previous buttons using Power Apps standard Fluent icons: ChevronRight, ChevronLeft etc.
2. Disable the buttons conditionally:
Display mode of Next button:

If(varCurrentIndex >= CountRows(colFilteredNews), DisplayMode.Disabled, DisplayMode.Edit)

Display mode of Previous button:

If(varCurrentIndex <= 1, DisplayMode.Disabled, DisplayMode.Edit)

3. You can optionally show current position like:

"News " & varCurrentIndex & " of " & CountRows(colFilteredNews)

Please give the mentioned solution a try and let me know whether it works for you.
