[Question] APK long packaging time

[Maskedviper]

Question

We are working on creating an app using Python and the Flet framework, after following several videos and links we are still running into an error in packaging the code as an apk file using the Flet framework. When we add the libraries one at a time they modulenotfounderror Is removed for the previous library not included but when we include all libraries in one go its taking hours for the packaging process and it still doesn't end up packaging. So I was wondering is this normal? Or how long does it take to package usually?

Can you send the log flet build apk app_name/ -vv

Mine is not that long (I didn't measure time) but sometimes i need to abort then restart the command

Maybe your flet version is not the latest one try pip install -U flet to update to latest version.

You should check Google IDX code editor for packaging flet app, mine take too long like 30 to 40 minutes in VS code(still causes an error) but when running on IDX it just take approx. 10 minutes. You just have to make a flutter project and then delete all the flutter related files not dev folder. and configure some variables like adding python 10 package and pip too, and then try to run flet build apk or any other platform command

@tanmay-bhatgare, can you please better explain how to have Flet running there? I gave it a try, but was unsuccessful.

Hello @ndonkoHenri,

To package your application, you should start by creating a Flutter project if you intend to build a mobile app. After that, remove all files related to Flutter, as they are not required for your Python application.

For the installation of Python, you should add pkgs.python10Full and pkgs.python310Packages.pip to the list of packages in the dev.nix file. Once this is done, rebuild your environment.

Next, create a virtual environment and proceed to install Flet. Please note that you can only use flet run --web since IDX does not support a built-in GUI. However, you can still use this method to package your application into an .apk file or any other format you desire.

I hope this helps!
