Describe the bug

I've been working in this bug for a week and searching for solve. When I build an apk, download to the phone and execute it works fine but when I build to aab and download through (internal test) Play Store and open the app it breaks in a blank screen with this (if you want to test it just send our gmail so I can insert in the internal testers list)

Using flet 0.25.2 flutter 3.24.2 and python 3.11.6 @ndonkoHenri

requirements.txt

flet==0.25.2
gql==3.5.0
requests==2.32.3
requests-toolbelt==1.0.0
Pint==0.24.4

main.py

from gql import Client
from gql.transport.requests import RequestsHTTPTransport
from services.classes import Droga, Solucao, Q_
from services.queries import (
    q_substancias,
    q_diluicao_padrao_por_id,

import re

from pint import UnitRegistry

ureg = UnitRegistry()
Q_ = ureg.Quantity
ureg.load_definitions("./services/pint_units_pt_br.txt")

class Droga:
    def __init__(self, ...

To reproduce

Download the package I wrote in the internal test available at https://play.google.com/apps/internaltest/4701557632548021360 (please send me your email from Google account)

Steps I've done to reproduce:

Installed packages including Pint It's a 100% Python
Create some classes in services/classes.py like:

import re

from pint import UnitRegistry

ureg = UnitRegistry()
Q_ = ureg.Quantity
ureg.load_definitions("./services/pint_units_pt_br.txt")

class Droga:
    def __init__(self, nome: str, concentracao:str, volume_ampola:str):
        self.nome = nome
        self.concentracao_ampola = Q_(concentracao)
        self.volume_ampola = Q_(volume_ampola)

    def consideracoes(self):
        return """
            Considerando que a concentração da ampola de {} é {:~},
            Considerando que estamos usando um volume de droga {} tem {:~}
            """.format(
            self.nome, self.concentracao_ampola, self.nome, self.volume_ampola
        )
...

but it breaks before class creation as the log says
3. Bundle it with signature flet build aab ... and send it to Play Store

Expected behavior

Runs as well as package build with flet build apk

So, just to confirm, it gives that TypeError: cannot inherit frozen dataclass from a non-frozen one Python error when deployed as .aab? Do you think I can reproduce it by making a simple app with @dataclass(frozen=True)?

FeodorFitsner · 2025-01-06T18:05:20Z

Studied the problem a bit. I'm not sure how come APK works, but AAB doesn't, but the only explanation could be the difference in pint of flexparser versions. There was an issue in pint itself: hgrecco/pint#1969 - incorrect inheritance of frozen/non-frozen dataclasses is treated as an error in the latest versions of Python. Unpack the contents of .aab and then pythonsitepackages.so and see what versions of pint and flexparser you have (this was a fix in pint). Hope that helps.

I don't know. I did not try it. When we come to the matter of uploading the app to the Google Play Store so we can test the aab file it can be hard to debug and create a test app in the platform.

I will try it out and let you know

filiperochalopes · 2025-01-06T23:18:44Z

@FeodorFitsner I ran a bunch of builds with many different envs multiple times. As I read in the Pint issues apparently It was fixed in Pint==0.24.4 and that is the version I am using. And the bug is just for Python 3.13 and I was using 3.11.6 and 3.12 but the bug information looks like a lot so I ran with Python 3.13 version. I removed almost all the code to test and when I introduced this line:

from pint import UnitRegistry

The bug shows again. But it's not the problem. The problem with flet are:
"Why not on apk?"
"Why not on flet run?"

Just when I build aab it happens. There are some extra packages involved that can conflict with another version of flexparser. I also unpack the aab and /build/app.zip show the same packages. I am using flexparser==0.4

Here the link to download apk https://files.filipelopes.me/share/PFgamCY4 It's working fine. Non sense

FeodorFitsner · 2025-01-07T20:12:38Z

Side note: You are embedding keystore.jks into .apk. Remove it from there and re-generate keys.

FeodorFitsner · 2025-01-07T20:15:46Z

OK, .apk contains pint 0.24.4 and flexparser 0.4. Check what's inside .aab. There couldn't be a miracle.

filiperochalopes · 2025-01-08T13:39:40Z

Side note: You are embedding keystore.jks into .apk. Remove it from there and re-generate keys.

🥲 Thank you! LOL I did not realize it until now. Is there some .gitignore thing for flet to list files to ignore on packaging?
