Flutter * Firebaseのエラー

Firebase
Flutter

結局firebaseが一番の問題であることが判明した（サンプルプロジェクト単体の場合は動くため)
とすると、pubsupec yamlで持ち込んだfirebaseが間違っていた可能性が高い。

errorコードがこれのようなのだが……

 uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [com.google.firebase:firebase-analytics:20.1.0] C:\Users\.gradle\caches\transforms-2\files-2.1\16f00cc28840d153ab6f9c1b8265da41\jetified-firebase-analytics-20.1.0\AndroidManifest.xml as the library might be using APIs not available in 16
        Suggestion: use a compatible library with a minSdk of at most 16,
                or increase this project's minSdk version to at least 19,
                or use tools:overrideLibrary="com.google.firebase.firebase_analytics" to force usage (may lead to runtime failures)

FAILURE: Build failed with an exception.

flutter runをしたら kotlin gradle pluginのエラーで怒られた

kotlin gradleプラグインのバージョンエラーっぽいので、バージョンの記入を変えたらなおりました。

android/gradle
buildscript {
    ext.kotlin_version = '1.6.10'
    repositories {
        google()
        mavenCentral()
    }```

エラーの詳細を見るため、
optionを色々試すのが良い。
flutter runは全部まとめてやってしまうので、一つ一つ見るといいかも。
