Overview
The jni package provides a Dart library for accessing Java Native Interface (JNI) from Flutter and Dart, enabling seamless interoperability with native Android code. It serves as a foundational support library for jnigen, simplifying the integration of native code written in languages like C or C++ with Dart applications. Designed for Android, Windows, and Linux platforms, it allows developers to call native functions directly from Dart, facilitating performance-critical operations and access to platform-specific features. The package is part of the Dart Native ecosystem, promoting efficient cross-platform native integration.
Use cases
- Calling native C/C++ functions from Dart
