jnigen

安装插件

flutter pub add jnigen

插件介绍

基于插件公开信息、社区数据与项目使用情况整理的选型参考。

Jnigen 是一个 Dart 包，用于生成 Java 和 Kotlin 代码的绑定，通过 JNI 实现与 Java 虚拟机的无缝互操作。它简化了在跨平台应用中从 Dart 调用 Java/Kotlin 函数的过程，特别适用于 Android 和其他基于 JVM 的环境。该工具自动化创建原生接口，减少样板代码并提高集成可靠性。它是 Dart Native 生态系统的一部分，支持包括 Android、iOS、macOS、Windows 和 Linux 在内的多个平台。

适合场景

从 Dart 调用 Java/Kotlin 库
集成原生 Android SDK
使用JVM代码扩展Dart应用
跨平台移动开发
使用原生性能构建混合应用

主要特点

自动生成 JNI 绑定
对 Java 和 Kotlin 的支持
多平台兼容性
与 Dart 原生生态系统的集成
减少手动 JNI 编码

适合对象

面向 Android 的 Dart 开发人员
使用 Java/Kotlin 库的团队
需要高性能原生互操作的项目
混合应用开发者
跨平台移动开发团队

使用建议

需要了解 JNI 概念
仅限 JVM 兼容平台
可能增加构建复杂性
不适用于纯Flutter应用
由于原生依赖项，应用程序大小可能更大
