This behaviour is inherited from App Inventor. You’re not allowed to use boxed types, such as Integer, Boolean, etc. You should instead use their primitive counterparts like int, boolean, etc.

I am not using such types on purpose. As you can see in the sample code, the specified return type is Int? but if you check the compiled code, kotlin makes the return type Integer unless you provide an alternate value using ?: or some other way.
This should never happen unless the type of _currentPost.id is Integer. Make sure it is Int.

I installed the rush and when I run it I get an error, why? This is the error:
bash: /data/data/com.termux/files/usr/bin/rush: Bad address
I also tried termux, but in my case the architecture of my device is aarch64 not x86_64, and when I install from github directly it just shows no such file or directory.
I ended up trying to build rush myself, by downloading Dart SDK for arm64 and try to build it with the help the instructions. The binary of rush is built successfully, and I can build extension smoothly.
Just one, big problem. When I upload the extension to Kodular / AI2, it gives me the error invalid stored block lengths even when I build the template extension without editing. I have no idea why this happens though.
I have never tested Rush on Termux. Will try to do that today and see if I can reproduce the issue.
Why did this fail for no reason, im trying to compile a project from today morning, i solved few errors, but this is there.

It is very difficult to say what’s exactly wrong. Do you mind PMing this extension’s source so I can try building it on my PC?
I think I have solved it (temporarily maybe).
Whenever this error occurs, i have to delete the .rush directory and run with the -r flag, after that i have to run normal build and that comes fine, I will PM you the source.
Error (I did not change anything in the code)

Deleting the files it says already exists solves the problem.
Please create a new issue on Rush’s GitHub repo for this and the previous issue.
That is the same issue I was talking about, they both are the same.
Nope, they are different. The first one doesn’t give enough info about why the build is failing, whereas the latter is a file system error.

Interesting, didn’t know rush enforce naming conventions in methods.
But wouldn’t it be better if there’s a flag to ignore this? (although discouraged)
No, Rush doesn’t enforce naming conventions, it just warns you about them.
@mordechay, your build is failing because you are using an unsupported type as your simple function’s parameter type.
public void onKeyDown(int keyCode, KeyEvent event) {
^^^^^^^^
You can only use the following types as parameter or return types:
String- Number types like
int,float,double, etc. java.util.Calendarboolean- Classes of all the available AI2 components and other runtime classes, like
Button,AndroidViewComponent, etc. - Some other AI2 types like
YailList,YailObjectandYailDictionary. java.lang.Object

@Shreyash is there any possibility for multiple extensions in one aix any time soon?
For e.g. Custom ListView - ColinTreeListView * · Appinventor/Thunkable Extensions
