Answered 2022-Jan-29 at 20:57Your second row is there and the .temp
div is place in that row. It's just that because the .temp
div has no content and the second row has a height of auto
that row and the .temp
div inside it have zero height and so are not visible. You can see what is going on more easily by adding outlines and minimum height:

I have an issue with which I've been battling for a couple of days now and I cannot understand what the problem is.
I want to fire up an event when a certain element hits the top of my
They're all span
, with different classes. I'm detecting the class with el.classList.contains("myclass")
. See my snippet below, with pagenum
in the function, which gets picked up (although several times, but that's another minor issue). It works with line
, line-group
, and pagenum
. It doesn't work with mspage
.
Can someone tell me please what I am missing?
Thanks.
UpdateI just noticed that if I give the mspage
elements a height of 2 rem then it does detect them. Ideally I wanted those span
s to be invisible to the user, and if I use display:none
or visibility:hidden
they don't get caught.
ANSWER
Answered 2022-Jan-27 at 02:33Using elementFromPoint
is not a good approach. Your interested element will not be detected if it doesn't happen to stay under that point. Even worse, the chances for a zero height element to be detected is zero. You should compare the offsetTop
of your interested element with the scrollTop + offsetTop
of the scrolling element. The find
can be further optimised with binary search if necessary.

QUESTION
I have following problem, I want to add a regular list view into the extended part of an extendable list view, I have tried to do it with following code:
...ANSWER
Answered 2021-Jun-05 at 21:37Well to fix the Overflow you can wrap your widget in a SingleChildScrollView
, anytime you paint more content than the available space on the screen you should use this or a ListView to be able to scroll.
As for the checkbox alongside each tile you were painting the checkbox before the ListView.builder
that created each expandedValue
so it was just created once for the listTile that contained the listivew and not for each item. Constructing the checkbox inside the listview.builder did the trick for that.
I also added a boolean property to the expandedValue
class to be able to check each item individually (IDK if this is the behavior you were seeking).

- Adding consistent space between the slices.
- Start the animation in sequence.
The reason, I didn't want the separator as a separate arch is to have both the edges rounded. Adding a separator as another layer overlaps the rounded corners.
Any help or pointers is highly appreciated.

QUESTION
I'm fairly new to programming (2-3 months in) and I'm struggling to find a way to fix this :
My goal : I've created a nested object with fantasy locations. I want to access the pop value from each of the "locations" I've generated and make the sum to know the total population.
Where I'm stuck : I can find and add the pop from the main object and its direct children, but for children of children it seems it doesn't work.
Here's a sample nested tree with a Parent location (Id:1), one children (Id: 2), and two grandchildren of Id 2 (id: 3 and 4).
...ANSWER
Answered 2020-Mar-23 at 03:30Please add an if condition check to check if there are any children to be actually checked like shown below, the for loop needs to be inside the if condition so that it doesn't error out when there are no children. You can also chain the null checks as shown below.
