Android app is stuck on splash screen

[shinewanna]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Flutter (Dart)

Steps to reproduce

I published Android build using CodeMagic, but the app is not opening with CodeMagic CICD.

Build success and deployed success but not opening after download from Firebase App Distribution and PlayStore.

It works well if I build and deploy locally.

After tracing the bug, found out Firebase Initialization is failing with CodeMagic CD/CD on Android.

    await Firebase.initializeApp(
       name: kIsWeb ? null : 'wyzauto',
      options: ProdFirebaseOptions.currentPlatform,
    );

I missed adding Firebase Android API Key and App Id in the CodeMagic environment variable configuration. It works correctly now.
