Proguard rules for Dart 2.0 & Hension?

[rockerhieu]

I tried the rules as documented in README.md but still get some warnings:

The below rules set work for me:

# Dart
-dontwarn com.f2prateek.dart.internal.**
-keep class **$$ExtraInjector { *; }
-keepclasseswithmembernames class * {
    @com.f2prateek.dart.* <fields>;
}
# Dart 2.0 & Henson
-keep class **Henson { *; }
-keep class **$$IntentBuilder { *; }
-dontwarn javax.**
-dontwarn java.**
-dontwarn com.f2prateek.dart.common.*
