| ## jnigen |
| |
| This project intends to provide 2 packages to enable JNI interop from Dart & Flutter. Currently this package is highly experimental. |
| |
| | Package | Description | |
| | ------- | --------- | |
| | [jni](jni/) | Ergonomic C bindings to JNI C API and several helper methods | |
| | [jnigen](jnigen/) | Tool to generate Dart bindings to Java code using FFI | |
| |
| This project is a work-in-progress and highly experimental. Users can check out and experiment with the examples. We do not guarantee stability of the API or commands at this point. |
| |
| ## SDK Requirements |
| Dart standalone target is supported, but due to some problems with pubspec, the `dart` command must be from Flutter SDK and not Dart SDK. See [dart-lang/pub#3563](https://github.com/dart-lang/pub/issues/3563). |
| |
| Along with JDK, maven (`mvn` command) is required. On Windows, it can be installed using a package manager such as `chocolatey` or `scoop`. |
| |
| It's recommended to have `clang-format` installed as well, to format the generated bindings. On Windows, it's part of the standard Clang install. On Linux, it can be installed through the package manager. |
| |
| On windows, you need to append the path of `jvm.dll` in your JDK installation to PATH. |
| |
| For example, on Powershell: |
| |
| ```powershell |
| $env:Path += ";${env:JAVA_HOME}\bin\server". |
| ``` |
| |
| (If JAVA_HOME not set, find the `java.exe` executable and set the environment variable in Control Panel). |
