# Run with `dart run ffigen --config ffigen.yaml`.
name: JniBindings
description: |
  Bindings for libdartjni.so which is part of jni plugin.

  It also transitively includes type definitions such as JNIEnv from third_party/jni.h;

  However, functions prefixed JNI_ are not usable because they are in a different shared library.

  Regenerate bindings with `flutter pub run ffigen.dart --config ffigen.yaml`.
