Flutter未知功能探索插件flutter_curiosity的使用

集成部分原生功能，支持 IOS Android macOS Windows Linux

Android

• 自动 添加 android http 允许请求配置
• 自动 添加 FileProvider 配置至 AndroidManifest
• 按需要 添加以下权限

<!--允许程序安装应用程序 可选-->
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>

介绍

• 原生方法 [获取GPS状态、获取app信息、监听键盘状态、获取android已安装应用、监听android activity result]

void fun() {
  Curiosity().native.fun(); // 调用原生方法
}

• 桌面端方法

void fun() {
  Curiosity().desktop.fun(); // 调用桌面端方法
}

• 桌面端窗口尺寸设置（支持 macOS Windows Linux）

void fun() {
  /// 设置桌面版 为 手机 或 ipad 尺寸
  DesktopWindowsSize.iPhone6P1.set(); // 设置窗口尺寸
}
