描述

Description

Our team realised that our apps we made, on certain Android device, the view doesnt go to the bottom edge of the screens. there's always a spacing. At first we thought it was React navigation that would create that spacings but we recently started a new project and we come to realise that it is native from React native. From the default source files of React native (the template we get from npx create-react-app) we have seen that the template use the SafeArea component, so we replaced it with a View component and tried with and without flex: 1 to his styles property but nothing changes, the spacings is still there. Is there a way of getting rid of it ?

调研方向

从 Snack 复现示例和通过 npx create-react-app 创建的新项目开始,在报告的 Pixel 6 设置上使用 React Native 0.72.12。将 SafeArea 组件与 View 进行比较,分别测试有无 flex: 1 的情况,并确定底部边缘的预期行为,以及不使用导航时是否可以复现该间距。
