Downgrading Xcode from 13.3 to 13.2.1 solved my problems.
I am getting "Unexpected end of stream" while using Retrofit (2.9.0) with OkHttp3 (4.9.1)
ANSWERAnswered 2022-Mar-27 at 18:38
OK, It took some time, but I've found what was going wrong and how to workaround that.
When Android Studio's emulators running in Windows series OS (checked for 7 & 10) receive json-typed reply from server with retrofit it can with various probability loose 1 or 2 last symbols of the body when it is decoded to string, this symbols contain closing curly brackets and so such body could not be parsed to object by gson converter which results in throwing exception.
The idea of workaround I found is to add an interceptor to retrofit which would check the decoded to string body if its last symbols match those of valid json response and add them if they are missed.
Goal: I have a ball in a triangle. The ball has an initial position and velocity. I'm trying to figure out which side of the triangle the ball will hit.
What I've Tried: I derived a formula that outputs which side the ball will hit, by parametrizing the ball's path and the triangle's sides, and finding the minimum time that satisfies the parametric equations. But when I implement this formula into my program, it produces the wrong results! I've tried many things, to no avail. Any help is greatly appreciated. The MWE is here: CodePen

I couldn't figure out your math. I think you should try annotating this kind of code with explanatory comments. Often that will help you spot your own mistake:
We are using keycloak as IDP and have some custom plugins/Spi, we are in process of updating our keycloak instance to version 17 Quarkas distribution and the SPIs began to break (error below) during keycloak build process. I've made sure that there are no keycloak libraries packed as part of jar.
The SPI looks like below and have corresponding entries in Manifest file under Manifest/services/org.keycloak.services.resource.RealmResourceProviderFactory

My app archive perfectly two weeks age (was the latest update I made).
After some minor changes in the flutter code (I did not add any packages or something), I am trying to archive again and I am getting some estrange errors and I have no clue where are coming from (those are from libraries, so no real changes on it). I am able to run it on the emulator and also I am able to build without any problem. I just can not archive.

This is an issue that occurs in version 13.3 of Xcode. In Xcode 13.3, if you have a code that uses UI_USER_INTERFACE_IDIOM(), you will get an "Out of Memory" error when you run Archive. Changing "UI_USER_INTERFACE_IDIOM()" to "UIDevice.current.userInterfaceIdiom" resolves the error.
Currently, we have the following solutions.
- Modify the code,
- Downgrade to Xcode 13.2.1
- Wait for Apple to modify Xcode

Chart.js is treeshakable since chart.js V3 so you will need to import and register all elements you are using.
Hello guys I am an iOS Developer building a Flutter app and I was wondering if the concept of memory cycle (retain cycle exists here). "Strong reference cycles negatively impact your application's performance. They lead to memory leaks and unexpected behaviour that is often hard to debug". By replacing a strong reference with a weak reference, the relationship between the objects remains intact and the strong reference cycle is broken. So in flutter there is no concept about weak reference. So how can you solve this problem, or there is no need to do that? Below I will leave an example....
ANSWERAnswered 2022-Feb-28 at 10:28
Dart uses a garbage collector. Apple's ARC does not use a garbage collector; objects are deallocated immediately and synchronously once they become unreferenced. That has some advantages (predictable, deterministic behavior) but some disadvantages (cycles created from mutual references).
Since garbage collectors run asynchronously and somewhat infrequently to process many potentially dead objects, they typically can afford to do more expensive operations, such as detecting and handling memory cycles. (For example, they can mark all currently reachable objects and delete everything else, a process known as mark-and-sweep.)
Additional reading about Dart's garbage collector:
- Flutter: Don’t Fear the Garbage Collector. (This article does not directly address your question, however.)
So usually you shouldn't need to worry about memory cycles in Dart. However, that doesn't mean that you can't "leak" memory. For example, if you register a callback on an object but never unregister it, as long as that callback remains registered (and therefore reachable), it will maintain a reference on the object and keep it alive.
Dart does (sort of) have a notion of weak references in the form of
Expando objects, but they aren't frequently used and have some limitations.
I'm trying to build a doughnut chart with rounded edges only on one side. My problem is that I have both sided rounded and not just on the one side. Also can't figure out how to do more foreground arcs not just one....
ANSWERAnswered 2022-Feb-28 at 08:52
The documentation states, that the corner radius is applied to both ends of the arc. Additionally, you want the arcs to overlap, which is also not the case.
You can add the one-sided rounded corners the following way:
- Use arcs
arcwith no corner radius for the data.
- Add additional
cornerjust for the rounded corner. These need to be shifted to the end of each
cornerhas rounded corners on both sides, add a
clipPaththat clips half of this arc. The
corner. This is essential for arcs smaller than two times the length of the rounded corners.
raiseall elements of
cornerto the front and then
sortthem descending by index, so that they overlap the right way.
