单页面时也会引入 react-navigation，体积过大

相关平台

React Native

使用框架: React

复现步骤

Taro RN 不分不管是单页面应用还是多页面应用 都会引入react-navigation ,达到了400多KB， 包体增大，在android 手机端，加载js 过程中会有 100毫秒左右的时间差

期望结果

单页面不引入

实际结果

引入

默认都会引入，在app.config 配置有一个开关打开，单页面就不会引入react-navigation, eg:

export default defineAppConfig({
  pages: [
    'pages/index/index'
 ],
  rn:{
    singleMode: true， // 默认是false
  }
})

如果pages的页面从一个到多个页面，需要重启下yarn start
