* Teach flutter tools to find gradle Flutter tools will now use Gradle from Android Studio, which is now found automatically. flutter doctor will verify that Android Studio has been installed, and that the included Gradle is at least version 2.14.1. It is still possible to manually configure the path to Android Studio (flutter config --android-studio-dir=XXX) or Gradle (flutter config --gradle-dir=XXX), but this should only be necessary if they're installed somewhere non-standard. Only tested on Linux and macOS for now. Fixes #8131
