I'm also seeing this with v2.0.3. See below for more info and a reproduction:

After adding the firebase_analytics plugin to a new flutter application (Stable Channel, migrated to androidX) a "uses unchecked or unsafe operations" warning is present when running a build (Android only).

The warning presented:

Note: /Users/dwulff/.pub-cache/hosted/pub.dartlang.org/firebase_analytics-2.0.3/android/src/main/java/io/flutter/plugins/firebaseanalytics/FirebaseAnalyticsPlugin.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Steps to Reproduce

option 1)

• clone https://github.com/danwulff/flutter_firebase_analytics_unsafe_warning.git
• run flutter run

option 2)

(using stable channel, v1.2.1)

• run flutter create ___
• migrate to AndroidX using Android Studio
• add firebase_analytics: 2.0.3 to pubspec.yaml
• run flutter run in a terminal
