# expo-config-plugin A guide to writing Expo Config Plugins. Automatically modifying native files (Info.plist, AndroidManifest.xml, build.gradle, Podfile) during prebuild. Plugin compose discipline, dangerous-mod usage, and the registration/test flow. The prebuild process itself lives in `expo-prebuild`. ## What It Does - iOS `Info.plist`, `entitlements.plist`, `Podfile`, `xcodeproj` modification - Android `AndroidManifest.xml`, `build.gradle`, `MainApplication.kt`, `strings.xml` modification - Plugin mod compose (`withPlugins`) - File writing with `withDangerousMod` (last resort) - Plugin tests (snapshot) - Registration and parameter passing in `app.config.ts` ## Plugin Structure ```ts // plugins/withMyPlugin.ts import { ConfigPlugin, withInfoPlist, withAndroidManifest, withDangerousMod, } from "expo/config-plugins"; type Props = { apiKey: string }; const withMyPlugin: ConfigPlugin<Props> = (config, { apiKey }) => { // iOS config = withInfoPlist(config, (cfg) => { cfg.modResults.MyApiKey = apiKey; cfg.modResults.NSCameraUsageDescription = "Camera access required"; return cfg; }); // Android config = withAndroidManifest(config, (cfg) => { const app = cfg.modResults.manifest.application?.[0]; if (app) { app["meta-data"] = app["meta-data"] || []; app["meta-data"].push({ $: { "android:name": "com.myapp.API_KEY", "android:value": apiKey }, }); } return cfg; }); return config; }; export default w
