Description

firebase_messaging 16.4.2 does not compile. FirebaseMessaging extends a base class named FirebasePlugin, but no published firebase_core_platform_interface defines that type. Any resolve that lands on 16.4.2 fails at build time:

firebase_messaging-16.4.2/lib/src/messaging.dart:11:33: Error: Type 'FirebasePlugin' not found.
class FirebaseMessaging extends FirebasePlugin {
                               ^^^^^^^^^^^^^^
firebase_messaging-16.4.2/lib/src/messaging.dart:21:36: Error: The getter 'pluginConstants' isn't defined for the type 'FirebaseMessaging'.
        app: app, pluginConstants: pluginConstants);
                                   ^^^^^^^^^^^^^^^
Target kernel_snapshot_program failed: Exception

What changed between 16.4.1 and 16.4.2:

16.4.1:  class FirebaseMessaging extends FirebasePluginPlatform   // compiles
16.4.2:  class FirebaseMessaging extends FirebasePlugin           // does not compile

firebase_messaging.dart pulls FirebasePlugin via show FirebasePlugin from firebase_core_platform_interface, but:

• firebase_core_platform_interface latest is 7.1.0, and it defines only FirebasePluginPlatform (extends PlatformInterface). No published version defines FirebasePlugin.
• firebase_core 4.12.0, which is 16.4.2's declared minimum, exports no Dart FirebasePlugin either.
• 16.4.2 constrains firebase_core_platform_interface: ^7.1.0, which resolves to 7.1.0 and lacks the symbol.

It looks like the FirebasePluginPlatform to FirebasePlugin rename shipped in the 16.4.2 publish, but the matching firebase_core_platform_interface release that actually defines FirebasePlugin was never published, or the constraint was not bumped to require it. 16.4.1 still extends FirebasePluginPlatform and compiles fine.

Reproducing the issue

1. Use any pubspec whose version range admits firebase_messaging 16.4.2.
2. Run flutter pub get. It resolves firebase_messaging 16.4.2, firebase_core 4.12.0, firebase_core_platform_interface 7.1.0.
3. Run flutter build for any target. Compilation fails with the errors above.

Workaround: pin firebase_messaging: 16.4.1.

I agree, firebase_messaging 16.4.2 is a broken upstream publish

I am seeing the same issue, can confirm.

I've had the same issue. I was able to get around this by pinning firebase_core to 4.11.0

firebase_core: 4.11.0
