@ui.refreshable decorators do not work when using native=True with Nicegui-pack

[imrrobat]

First Check

• I added a very descriptive title here.
• This is not a Q&A. I am sure something is wrong with NiceGUI or its documentation.
• I used the GitHub search to find a similar issue and came up empty.

Example Code

from nicegui import ui 

ui.lable('hi')

ui.run(native=True)

Description

Hi,

I've noticed that when I build a Nicegui application into an .exe using Nicegui-pack with native=True, the @ui.refreshable decorators stop working (with pyw format) . The UI does not update as expected.

Steps to reproduce:

Create a Nicegui app using @ui.refreshable.

Build the app with nicegui-pack build --native True.

Run the resulting .exe.

Observe that the refreshable components do not update.

Expected behavior:
The @ui.refreshable components should update as they do when running the app normally (python app.py).

The venv is:

OS: Windows 11 ltsc
Python: 3.13.7
NiceGUI: 2.24.2

The command is nicegui-pack --onefile --name "myapp" main.py.
The code is:

from nicegui import ui

def index():
    @ui.refreshable
    def rebuild():
        num,set_num = ui.state(1)
        my_input = ui.number(
            '个数',
            value=num,
            min=1,
            max=10,
            format='%d'
        )
        # 修改保存值
        my_input.on_value_change(
            lambda :set_num(my_input.value)
        )
        my_input.on_value_change(
            rebuild.refresh
        )
        for i in range(int(my_input.value)):
            ui.label('A')
    rebuild()

index()
ui.run(
    #root=index, 
    native=True,
    reload=False
)

It works well:

BTW,You shoud use reload=False and follow the instruction (https://nicegui.io/documentation/section_configuration_deployment#package_for_installation).
Providing a accurate minimal executable example (MRE) will help others to solve problem. Thank you.

Hi @imrrobat,
I agree with @python-and-novella: Please share your app code and the exact nicegui-pack command so that we can try reproducing the problem more easily. Thanks!

[imrrobat]

hello @falkoschindler and @python-and-novella
yeah it's ok but i also want to hide terminal opened with app so i change format from py to pyw and in this situation doesn't work

[python-and-novella]

@imrrobat Use nicegui-pack --onefile --windowed --name "myapp" main.py. see it in https://nicegui.io/documentation/section_configuration_deployment#package_for_installation .

[imrrobat]

@python-and-novella thanks for help but it won't work either

[python-and-novella]

@imrrobat Plz show MRE, environment info and video.

[imrrobat]

@python-and-novella i just record a video:

thanks for attention.

[python-and-novella]

@imrrobat You should provide a MRE, I think it is relate to your code. At least, my example works.
The terminal will print errors if your code has bug, so try nicegui-pack --onefile --name "myapp" main.py to enable terminal, and check the output plz.

[imrrobat]

@python-and-novella how can i provide MRE?

[python-and-novella]

@imrrobat just provide necessary code which reproduces problem and can be execute directly.
