You are trying to build an apk, but the flutter android-related stuffs seem not to be okay.
Also, can you share your requirements.txt ?

[jk-2022]

ok, pour mon requirements.txt, j'ai que flet et flet-material

[ndonkoHenri]

Ok. Now just make sure flutter returns no error.
Then try to rebuild.

[jk-2022]

flutter doctor
