Description

hello,
I have already reviewed the relevant answers in the issues.
The versions I am using are:
firebase_core: ^4.4.0
firebase_messaging: ^16.1.1
flutter doctor -v:
[✓] Flutter (Channel stable, 3.32.7, on macOS 15.3.1 24D70 darwin-arm64, locale zh-Hant-TW) [437ms]
• Flutter version 3.32.7 on channel stable at /Users/zhangweixuan/Desktop/flutter
• Upstream repository https://github.com/flutter/flutter.git
• Framework revision d7b523b356 (7 months ago), 2025-07-15 17:03:46 -0700
• Engine revision 39d6d6e699
• Dart version 3.8.1
• DevTools version 2.45.1
I have already set:
isMinifyEnabled = false
isShrinkResources = false
I have also tested upgrading to firebase_core_platform_interface 6.0.2.
However, the issue still persists on the Android release version.
Are there any other possible solutions?

@colaTW I also encountered a similar problem here, and the troubleshooting found that firebase_core depended on 4.4.0 but firebase_core_platform_interface depended on error v5.4.0 (need v6.0.2 ) cause this question。

dependency_overrides:
  firebase_core_platform_interface: 6.0.2
