Dart can't find injector when using Proguard

After enabling minifyEnabled for release build, crashes start occurring. I have a proguard-rules:

-dontwarn com.f2prateek.dart.internal.**
-keep class **$$ExtraInjector { *; }
-keepclasseswithmembernames class * {
    @com.f2prateek.dart.* <fields>;
}

and seeing in log:

02-08 22:03:31.765 11321-11440/? D/Dart: Looking up extra injector for pl.srw.service.AService
02-08 22:03:31.767 11321-11440/? D/Dart: Not found. Trying superclass pl.srw.service.a
02-08 22:03:31.768 11321-11440/? D/Dart: Not found. Trying superclass android.app.IntentService
02-08 22:03:31.768 11321-11440/? D/Dart: MISS: Reached framework class. Abandoning search.

I’m on version 1.1.0

@bmarty you are right, I changed it and it works. Here you can find the sources and PR: https://github.com/f2prateek/dart/pull/163

@stephanenicolas let me know any problems

Hi, I see that after removing the last field with @Bind from my fragment, the fragment class is now obfuscated.

So I conclude that the proguard rule:

-keepclasseswithmembernames class * {
    @com.f2prateek.dart.* <fields>;
}

does not work and

-keepclasseswithmembernames class * {
    @butterknife.* <fields>;
}

works.

The diff between @Bind and @InjectExtra is that the first has CLASS retention and the second has SOURCE retention.

=> It is just an idea, but maybe @InjectExtra should have CLASS retention to fix this issue
