Hello,

3 days ago I upgraded to "Flet v.0.23" and I upgraded "Flutter" to last version and for me (in Linux) it was a complete disaster.

Tonight I'm going to try v0.23.1 in Linux. (code and build)

In windows I can code normally with v.0.23.1 (I didn't try to build yet....)

Best regards.

Hello.

I confirm in Linux (Ubuntu 24.04 - Linux 6.8.0-35-generic - Gnome 46 ) is possible code but not possible to build (the same issue, white screen).

Thanks.

Hello.

I can confirm in MacOS (14.5 - Intel Processor) I can't even "compile" code with Visual Studio. Black screen appears.

Thanks, best regards

It is fixed in Flet 0.23.1.

Please cleanup Cookiecutter cache before running flet build command.

On Windows:

rd /s /q %USERPROFILE%\.cookiecutters

On Mac/Linux:

rm -rf ~/.cookiecutters

Now tested on Windows and working for apk! The size is also correct and is about 40 MB as in the old versions

[nastiliano]

Tested in Linux. Ok again!

Thank you very much.

In 0.23.2 build apk is working, but the apk size with the counter example is about 140 MB, in the mobile device the final size is 188MB and this generate CACHE and DATA (224 MB). The first run display a whitescreen, but if i wait a few moment (one or two minutes) the app run (i understand that app generate the DATA and CACHE). How can i accelerate this process?. Or, how can i jump this process of whitescreen?? Other problem that i found is so that run the app i try to open this two or three times. How can i fix this?

I am still having the white screen, it seems it's only fixed on some systems. I am on Window 11, Flet 0.23.2 and I already tried deleting the Cookiecutter cache

And on MacOS Sonoma black screen too.

Try to install the last beta version:

pip install flet==0.24.0.dev3274

It "works" (more or less) on MacOS Sonoma.

Thanks

I can build and run the flet app. FLET VERSION : 0.23.1 FLUTTER VERSION: Flutter 3.24.0 • channel stable • https://github.com/flutter/flutter.git Framework • revision 80c2e84975 (3 weeks ago) • 2024-07-30 23:06:49 +0700 Engine • revision b8800d88be Tools • Dart 3.5.0 • DevTools 2.37.2. But the first run of the app on Android (phone) it takes a long time to appear the main page. Can be it solved?

The script is quite simple, but it always displays a white screen on Android (emulator and real phone). Here is the code: https://gist.github.com/sorincodes/cc3ccc71772e57cbeb88036a0e6cf29e
