Well, I've run into a problem with my StackView

QUESTION
I am quite new to Flutter and I am enjoying the framework very much. However, I have been getting stuck on the following:
The problem: Users need to be able to make reservations for certain sports assets. I decided to go with the following approach regarding the UI.
Concept layout
The layout features a row with the name of the asset. After that a vertical vertical scrolling row (all rows scroll at the same time such that it's easy to look up a free spot). These vertical scrolling bars contain the reservations, allowing you to scroll through all hours of the day.
I tried finding an existing layout that would help me here, sadly with no luck. Having tried some methods of my own (horizontal listview with vertical listviews) I did not manage to solve this problem.
The questions I have now are the following:
- Did I miss a framework that already solves this issue?
- How would one go about spacing out the items in the vertical listview (regarding time 'slots')? Using Containers with margins seems a bit harsh.
- Is it possible to sync all vertical listviews with each other?
Any hints or answers are much appreciated!

The vertical listsIn order to construct the vertical lists, I used the following code. This constructs one timetable for an asset.

QUESTION
I am running into this weird issue that the app does not load the page content unless I hit ctrl + s in VScode(hot reload).
The following code gets a list of emotion names from the database and loads them onto the screen.
...ANSWER
Answered 2022-Mar-13 at 00:12Your guess that you need to use setState
is correct. The reason setState
is needed is that it takes time to gather the data from the database, in the time that takes, the rest of your page renders in. When you actually receive the data you need to notify a re-render with your new data.
You can implement this by adding a fetchEmotionData
function like the one below.

There are actually 2 separated listViews, one should contain a single card and another that holds a list of cards.

QUESTION
I'd like to ask when using the FutureBuilder
to display fetched data from a remote server in a ListView
. I check if the bottom of the ListView
was reached using ScrollController
. Everything is working well until I try to load new data and append them to the existing ListView
I fetch the data add them to my Array
and the in setState((){})
I update the list for the FutureBuilder
this is obviously the wrong approach since then the whole FutureBuilder
is rebuilt and so is the ListView
. The changes however do appear all the new items are in the list as intended however it slows performance not significantly since ListView
is not keeping tiles out of view active but it has a small impact on performance, but the main issue is that since ListView
gets rebuilt, I'm thrown as a user to the start of this list that's because the ListView
got rebuilt. Now what I would like to achieve is that the ListView
doesn't get rebuilt every time I get new data. Here is the code of the whole StateFulWidget
ANSWER
Answered 2022-Feb-23 at 05:30What you need is to hold onto the state in some Listenable
, such as ValueNotifier
and use ValueListenableBuilder
to build your ListView
. I put together this demo to show you what I mean:
QUESTION
I'm using MouseMove, MouseUp, MouseDown events to move a borderless form (as found here as an example).
It works great, but for ListViews, it only works if I click on an item (its text) in the list. It does not work if I click in the space of the ListView containing no items.
Is there a possible way to fix this?
...ANSWER
Answered 2022-Feb-17 at 03:32To move a Form, clicking and dragging any Control, you can implement the IMessageFilter Interface. You'll receive messages before they're sent to the target Control (with the option to suppress them, returning true
).
The implementation requires that you implement PreFilterMessage.
Store the current Mouse Position when the message is WM_LBUTTONDOWN
and move the Form when it's WM_MOUSEMOVE
, if the left Button is still pressed (the Buttons currently pressed are specified in WParam
, see the Docs about this).
Use Application.AddMessageFilter to register the class that implements the interface (the Form itself, in this case). Here, it's called in OnHandleCreated
.
Call Application.RemoveMessageFilter to remove the filter. Here, called in OnHandleDestroyed
.
Note that I've used Capture = true;
in WM_MOUSEMOVE
, so pressing the left mouse button and dragging, e.g., a Button Control, won't cause - in this case - a Click event.
Modify it if you don't like it.
Note:
As Reza Aghaei suggested, if you set your ListView to MultiSelect = false
, you can then click anywhere on it to drag the Form.
