Problems with the update 0.27.1

[ingdesarr1]

Question

Good morning. Yesterday, I update flet to version 0.27.1. I have an application that I have updated little by little with each new version of flet, but yesterday when I updated the application it stopped working correctly. When I make a change to some element it does not recognize it, neither in the main nor in anything, nor does it take any errors that may be generated, such as a function that no longer exists or so on, I don't know if I need to update something else or it could be a version problem. What else can I validate to identify the error? Thank you

Can you try creating a new venv, and then installing Flet with pip install 'flet[all]'

[ingdesarr1]

I create a new venv with the libraries, and doesn't work. I attach a video to show the problem. Here is the list of libraries installed.

Flet27.mp4

[ingdesarr1]

I think I found the problem, but I don't know why. In my project folder, I have a folder with a compilation of the app, created with flet build, when I was using flet 0.25. When I was using the flet version ==0.25, all the changes in my project work well, but when I updated to 0.27, for some reason, when I execute the command in the terminal to run my app, the changes were not visible. I create a new folder with all my project and it still doesn't work, but, I delete the folder with the previously build, and all the changes run well.

@ndonkoHenri @FeodorFitsner maybe, you can check what happened, because I don't understand.

[ingdesarr1]

I have another problem. The build function in the Custom Controls not working. I'm trying to print some message and save some information in the build and not working. In the previous versions, it was working fine.

[ndonkoHenri]

@ingdesarr1 upgrade to the latest Flet version. It has been fixed.
