Importing Firebase_Messaging makes build fail

Question

When I import firebase_messaging into my app(in pubspec.yaml and an import statement). My app fails to build. It was working perfectly before trying to import firebase_messaging. I checked the flutter directory to make sure it was the right version and everything. I'm kind of at a loss here.

I tried updating android, and flutter.

Pubspec.yaml

     dependencies:
  firebase_core: ^0.4.0+6
  firebase_analytics: ^3.0.2
  cloud_firestore: ^0.12.5+1

  firebase_auth: ^0.11.1+6
  google_sign_in: ^4.0.2
  rxdart: ^0.22.0
  css_colors: ^1.0.2
  flutter_auth_buttons: ^0.5.0
  firebase_messaging: ^5.1.2

This is the error message

     Could not determine the dependencies of task 
':app:compileDebugJavaWithJavac'.
> In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[18.0.
  0]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

  Dependency failing: com.google.firebase:firebase-messaging:18.0.0 -> com.google.firebase:firebase-iid@[18.0.0], but fire
 base-iid version was 19.0.0.

 The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art
 ifact with the issue.

  For extended debugging info execute Gradle from the command line with 
./gradlew --info :app:assembleDebug to see the dep
  endency paths to the artifact. This error message came from the google- 
   services Gradle plugin, report issues at https://
  github.com/google/play-services-plugins and disable by adding 
"googleServices { disableVersionCheck = false }" to your b
   uild.gradle file.

* Try:
 Run with --stacktrace option to get the stack trace. Run with --info or -- 
debug option to get more log output. Run with --scan to get full insights.

Solution

Ok so after doing a bit more research I found out an answer. I added implementation 'com.google.firebase:firebase-messaging:19.0.1' to my app level gradle file and I get some warnings, but the app itself builds and runs.

Thank you! This was driving me crazy. How have more people not run into this issue? I followed the documentation exactly, and this was definitely not in it. If anyone knows I would love to know, I'm pretty clueless with this stuff still.
