I have a database of items, now I need to update the pictures in 10,000 records in the database, I make an API request, I receive an answer, but I just cannot process the answer correctly.

I received result:

I am trying to implement a barcode scanner app in Flutter where the camera can be embedded as a widget rather than making it fullscreen.

So I went with the flutter_qr_mobile_vision package as we can use the native camera features and also restricting the camera preview size.

But the above package gives only the barcode string which is detected by the MLKit and not the barcode details like bounding box, barcode type, and other information, so I took the source code of the above package and made some changes so that I get the bounding box which can be used to overlay a graphic on the detected barcode(s).

The code for what im trying to do can be found here

Now I'm facing two problems while using these changes (Android implementation only as of now)

1. When I'm trying to overlay the bounding box on top of the barcode, results are inconsistent across multiple devices.

For example:

Works fine on oneplus in fullscreen

Same code output on Redmi 5

I have kept the camera resolution by default as (1280 x 720) for all the devices and scaling the output as well before overlaying

I'm trying to understand what is causing this on different devices

1. Now If I try to resize the widget height of the camera preview, the results are inconsistent on oneplus as well

I feel this is something to do with the scaling part but im not sure.

Below code is for camera preview and overlay graphic

How do I set a custom value for environmental-variable in case if display has cutouts?

Assuming that browser supports ENV

If I set:

I have a simple task: I have an image and an array of points. For each point I want to slice boxes out of the image.

I can do this in a for loop, but for thousands of points it is very slow, so I need to do this without loops. I'm trying to broadcast arrays to the slice values. Here's some minimal code that illustrates the problem:

I'm trying to determine the position of the DisplayCutout(notch).

The Android Developer Blog, state the following:

In Android P we added APIs to let you manage how your app uses the display cutout area, as well as to check for the presence of cutouts and get their positions.

So I tried getting the position of the cutout, this is the only way I was able to get it:

I am creating an Android App in which I am showing a floating view on top of all apps by using a service and Window Manager. I am trying to add WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES in my Window Manager params to enable my layout to overlay with display cutouts. But it seems like this is not working in my case.

I have already tried to add it in both ways:

1. By using XML styling:

I need to build a 5-star rating system in Oracle Apex.

For reference, here is a basic modal dialog for one of my database tables.

It shows the rating for this item as 3.5
The value comes directly from a column in my table.

Instead of displaying the numeric value, I'd like to display something like this:

I'm new to Apex, so I don't know where to begin.
My first instinct is to (somehow) create a dynamically sized gold rectangle, which changes size based on the numeric value, and then put some type of "mask" in front of it to cover everything except the star shapes.

Creating a "mask" image with transparent star cutouts is easy, but implementing this display seems like it might require some more advanced Apex skills. (custom JavaScript?)

Or maybe there's a better method, I have no idea.

In addition to being able to display the number of stars, I also need users to be able to click on the stars to set the rating.
They should be able to select any rating from 0-5 in increments of 1/2 star.

Where should I begin with a problem like this?
Does Apex have built-in support for custom controls?
Are they relatively simple to implement?

I have a weird question, it concerns slicing arrays and extract small thumbnail cutouts. I do have a solution, but it's a chunky for loop which runs fairly slowly on big images.

The current solution looks something like this:

I'm developing an Android application with the Android Studio template "Navigation Drawer Activity" but if I open the navigation drawer on a phone with Notch/display Cutouts the bigger status bar cover the top of the Navigation Drawer header.

How could I fix this?

Here are the Activity layout xml:
