app creation help
Qual versão do Flutter está sendo usada no projeto? Eu baixei recentemente a versão do CodeCanyon, mas quando tento compilar o sistema, aparece uma mensagem dizendo que eu preciso usar a versão 3.38.5 do Flutter e o Dart ≥ 3.10.
Qual versão do Flutter devo usar?

Good morning,
I believe I have configured Firebase correctly.
I am sending you my code for you to check: https://drive.google.com/file/d/1hlS0_aWgNREwQVT1ORjH_VnOZotFM8OQ/view?usp=sharing
I had already added the SHA256 and SHA1 to Firebase and placed the GoogleServi.json file in the correct location. Please check what is happening or indicate where I should make the modification. Thank you, good morning.

Hi there,
Thanks for reaching out with your queries.
1. For the issue of the app getting stucked on startup, Check the following conditions
- If you properly configured firebase. This includes adding the package name, SHA256 key, etc
- Check if you properly added the google_service.json file in the correct location
android/app/{GOOGLE SERVICE JSON FILE SHOULD BE HERE}
2. In order to add the server url, search for the file app_server_config.dart and you can add your server url there
NB: This would be updated in the docs at the latest.
3. In order to hide the online option, naviagate to PaymentModel.dart and comment out the online option.

I'm getting an error when I try to build, see the attached image.
The app is stuck on the white screen.
Errors: E/flutter (14392): [ERROR:flutter/runtime/dart_vm_initializer.cc(40)] Unhandled Exception: [core/duplicate-app] A Firebase App named "[DEFAULT]" already exists

I need help because in the documentation you state:
In the main directory, access lib → app_config.dart const DOMAIN_URL = "ADD YOUR DOMAIN URL";
but this no longer exists in the project, not with this name. Where do I add the server URL, the baseURL?

And I also have another question: I won't be using any online payment methods, do I need to remove payment methods from the app?
