expo-required-hardware

This Expo plugin allows you to specify hardware requirements for your app. It is useful for apps that require specific hardware features to function properly like a front-facing camera, GPS, or Bluetooth.

Overview

This plugin provides an easy interface to specify hardware requirements for your app. It does this during the expo prebuild phase and will modify your AndroidManifest.xml and Info.plist files to include the necessary hardware features.

Note that this config plugin may restrict the types and number of devices that your app can be installed on. For example, if you require a front-facing camera, your app will not be installable on devices that do not have a front-facing camera. This will be restricted at the appstore level due to the entries that this plugin helps specify in the AndroidManifest.xml and Info.plist files.
