| #### Developer's Note |
| |
| One-off patch of [ffigen](https://github.com/dart-lang/ffigen) for generating bindings of some JNI structs. |
| |
| Only changes to ffigen source are made in lib/src/code_generator/compound.dart file. The purpose of these changes is to write the extension methods along with certain types, which make calling function pointer fields easier. |
| |
| The modified FFIGEN is used to generate `lib/src/third_party/jni_bindings_generated.dart` using both header files in src/ and third_party/jni.h (the JNI header file from Android NDK). This provides bulk of our interface to JNI through FFI. |
