Issue 2:
Hi, I'm adding flutter to an existing app, it works well basically, I can successfully run the hybrid app and assembleDebug/assembleRelease to generate apk files. However when I use ./gradlew build command to build the application, it fails with an exception.

Task :flutter:flutterBuildDynamicRelease

Crash report written to /Users/some_path/some_application/flutter_07.log;

please let us know at https://github.com/flutter/flutter/issues.

Task :flutter:flutterBuildDynamicRelease FAILED

The following is what the flutter_07.logsays, it's implying me that product_vm_isolate_snapshot.bin cannot be found, I browsed the folder and the file wasn't there.. I downloaded the latest flutter_macos_v0.9.4-beta.zip and still cannot find product_vm_isolate_snapshot.bin.

What should I do?

thank you
