I have a layout where I have two scroll views, one is a PageView which is used to display a list of pictures horizontally, the second is a SingleChildScrollView (maybe should be something else?), this scroll view is partially above the first one as initial position and can go completely over. Some screenshots to image this:

The problem is, if I make the 2nd scroll view take all page and add internal padding to it to make it the good height, the 2nd scroll view work as expected but the first one (witch is behind) isn't working anymore. The 2nd solution would be to wrap the SingleChildScrollView with a Padding widget to make it the good height and add Clip.none parameter to the scroll view, but in this case the scroll view cannot be scrolled in PageView zone even if the SingleChildScrollViewis over.

I wonder if someone already encountered a behavior like this and what is your solution.

Here my actual code with second solution:

I've managed to adjust color when cursor hovers over a tkinter canvas rounded rectangle button using this:

I am trying to implement frustum culling in my 3D Game currently and it has worked efficiently with the entities because they have a bounding box (AABB) and its easier to check a box against the frustum. On saying that, how would I cull the terrain? (it physically cannot have a AABB or sphere)

The frustum class (I use the inbuilt JOML one):

I'm trying to make each grid with different color the value is coming from the controller (from api)

I cant reach every grid because using the map doesn't provide an index for each grid.

is there another way to view these grids or another way to color each one with different color?

here is the code :

I'm trying to add multiple lists into a text file, but all the strings inside are closed together when I try this method. My goal is to separate the strings inside.

Scenario : From the following XML, Concatenate the marks and subject of a student with a "-" and put it as output in JSON.

Input:

I made a website with PageController to control the scroll of some screens. And I made a menu section with screen names, and when any of them are pressed, the user will navigate to the respective screen.

The app is working fine. But I refactored the menu button so I can control it's style, and to add animation in the future.

But when I refactored the button, I can't pass the PageController index, or the nextPage function.

That's why I thought of using the provider package. However, I didn't the package before, and my setup seems complex. For I should pass the PageController state to the button, and the button should send the nextPage function with a new number.

How can I achieve this?

Here's my code:

The button:

Scenario: Need to convert Incoming XML message to JSON but maintain all the data. Input :

Here when I type inside text fields Keyboard covers the Login button. So I need to scroll down to the Login button when typing. I tried wrapping LayoutBuilder with SingleChildScrollView and tried using Positioned widget inside Stack but nothing solved my issue. And I set physics to AlwaysScrollableScrollPhysics() inside SingleChildScrollView but it also didn't solve the problem. I can't figure out what I've done wrong. I would be grateful if anyone can help me with this issue

Here's my code
