Current Behavior

While trying to build our app, we were getting warning logs like this:

~/.pub-cache/hosted/pub.dev/karte_core-1.3.0/android/src/main/java/io/karte/flutter/core/KarteCorePlugin.java:73: 警告:[deprecation] PluginRegistryのRegistrarは推奨されません
    public static void registerWith(PluginRegistry.Registrar registrar) {
                                                  ^
~/.pub-cache/hosted/pub.dev/karte_core-1.3.0/android/src/main/java/io/karte/flutter/core/KarteCorePlugin.java:153: 警告:[deprecation] Trackerのidentify(Map<String,?>)は推奨されません
                    Tracker.identify(values != null ? values : new HashMap<String, Object>());
                           ^
~/.pub-cache/hosted/pub.dev/karte_core-1.3.0/android/src/main/java/io/karte/flutter/core/KarteCorePlugin.java:181: 警告:[deprecation] UserSyncのappendUserSyncQueryParameter(String)は推奨されません
                    result.success(UserSync.appendUserSyncQueryParameter(url));

Add the following to android/build.gradle to output the above log.

allprojects {
    repositories {
        google()
        mavenCentral()
    }
  //　add code.
  gradle.projectsEvaluated {
    tasks.withType(JavaCompile) {
      options.compilerArgs << "-Xlint:deprecation"
    }
  }
