[Question] how to make Executable file with [Navigation and routing]??

[jjjunehkim]

Question

The desired execution process is as follows.

After being created a Executable file(.exe file),
Run a Executable file(.exe file) on "A"computer(PC)
And connect "http://192.168.35.35:8550/data_table on "B" computer(PC)

So, I am trying to make a Executable file(.exe file) through the process below.
Could you help me?

1. Use this command -> flet pack myapp.py (myapp.py : scripts name)
2. A executable file(myapp.exe) was created in the dist folder.
3. Run a myapp.exe
4. Error window opened
   

---

And I tried other method "flet build". after change file name (myapp.py -> main.py) for using the command("flet build windows")
->>> command : flet build windows

Creating Flutter bootstrap project...OK
Customizing app icons and splash images...OK
Generating app icons...OK
Packaging Python app...OK
Building Windows app...OK
Copying build to build\windows directory...OK
Success!

And......
I run the Executable file(.exe file) on "A"computer. it work.
and I opened chorome browser.
and I try to connect <"http://192.168.35.35:8550/data_table" in the chrome browser address bar>on "B" computer(PC)
but it was not opened on "B"computer.

One more trial!!!!
And I tried other method "flet build". after change file name (myapp.py -> main.py) for using the command("flet build web")
->>> command : flet build web

It also didn't work as expected.

• I have searched for answers to my question both in the issues and in previous discussions.

I use auto-py-to-exe and works fine, maybe you can try it.

[ingdesarr1]

in your project, you use any other file or dependence? maybe you are not attach to project. what other files you use?

[jjjunehkim]

I executed the code that I posted when I asked the first question.
The one at the top is the sample code I ran.

[ndonkoHenri]

Which windows version are you using exactly ?

[jjjunehkim]

Version : Window 11 pro 22H2

Is it related to the Windows version?

[jjjunehkim]

I will explain it in detail again

I hope to be executed like either "first case" or "second case" when I run a executable file(.exe file)

1. first case
( command in a command terminal )
after then,
-> When you click the <add_data> button for "A PC" and the <add_data> button for "B PC", data table rows for both "A PC" and "B PC" are added.

Image executed only as an app when executing the command in the command terminal of "A" PC

Image opened in the chrome browser of "B" PC on the same network after running the command in the command terminal of "A" PC

2..Second case
(<(python main.py> command in a command terminal )
after then,
-> When you click the <add_data> button for "A PC" and the <add_data> button for "B PC", data table rows for both "A PC" and "B PC" are added.
Image opened in Chrome browser after executing the command in the command terminal of "A PC"

Image opened in the chrome browser of "B" PC on the same network after executing the command in the command terminal of "A" PC

=================================================================================

Result :
run a executable file(.exe file) created as the command
after then,
-> When you click the <add_data> button for "A PC" , data table rows for "A PC" are added.
HTTP ERROR 404 in Chrome browser of "B" PC

Image when executing the executable file created with the command on "A" PC

The image opened in the Chrome browser on "B" PC, after executing the executable file created with the command on "A" PC.
