This is the code which tries to find gradle: https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/android/gradle.dart#L37

The flutter command is located inside the bin directory of the flutter SDK you downloaded. Adding it to your path is covered in our setup docs: https://flutter.io/setup/#get-the-flutter-sdk

You can specify the location of your gradle binary using args to the commands or globally using flutter config with the --gradle-dir or --android-studio-dir flags.

As you can see in the linked code, we know how to find gradle in some default locations, such as inside /Applications/Android Studio.app or by reading your path variable. We probably could add more default locations.

If you believe your Android SDK is installed in a default location we're not checking please file a bug at https://github.com/flutter/flutter/issues/new and we're happy to fix.
