ImagePickerKMP is a Kotlin Multiplatform library (not a standalone application) that delivers production-grade media picking and barcode scanning capabilities for Android, iOS, JVM desktop, and web/JS/Wasm targets. The photo module (imagepickerkmp-photo) provides camera capture, gallery selection, image cropping, EXIF extraction with GPS redaction, configurable compression (LOW/MEDIUM/HIGH), and permission-request UI, all driven through a Compose Multiplatform API centered on rememberImagePickerKMP(). The scanner module (imagepickerkmp-scanner) provides continuous barcode/QR scanning with auto-zoom, distance warnings, batch mode, phantom-code suppression, and enterprise inactivity overlays, using ML Kit on Android and AVFoundation/Vision on iOS. A shared imagepicker-core module abstracts permissions, filesystem access, URI handling, language detection, and logging across platforms via the Kotlin expect/actual mechanism. The library is distributed as versioned Maven artifacts with a published JS bundle for web integration. Architecturally, the codebase is a modular multi-artifact Gradle project: imagepicker-core (infrastructure), imagepickerkmp-photo, and imagepickerkmp-scanner, with each module enforcing dependency boundaries (the scanner module explicitly prohibits depending on the photo module). Its design leans on config-driven API design (large nested data classes such as ImagePickerKMPConfig and ScannerBehaviorConfig with runtime validation), observable state holders (sealed Idle/Loading/Success/Dismissed/Error states backed by Compose mutableStateOf), and event-driven scanner orchestration. Platform-specific behavior is cleanly isolated through expect/actual: Android uses CameraX, ActivityResultContracts, and ExifInterface; iOS uses UIImagePickerController, PHPicker, PhotosUI, and CoreGraphics; desktop/web use file choosers or documented no-op stubs where camera hardware is unavailable. Localization spans 14 languages via YAML translation files and the i18nkonfig plugin, and CI (GitHub Actions) runs detekt static analysis, Kover coverage verification with a 90% line minimum, unit tests across commonTest/androidUnitTest/iosTest, and publishes coverage to Codecov. Maintenance is active: a recent commit history on the develop branch, one open issue, zero Dependabot alerts, and continuously updated Kotlin 2.x / Compose Multiplatform versions indicate steady upkeep. Known rough edges include intentionally blank PlatformPrewarm files, crop implementation stubs on JS/WASM, a handful of placeholder tests asserting true, duplicated permission-handling logic across photo/scanner modules, and a potentially stale build-and-bundle.sh referencing an old JS build path. Overall, this is a well-crafted, professionally engineered KMP library with genuinely reusable cross-platform abstractions and strong test discipline; it is a solid reference for Kotlin Multiplatform architecture and Compose-based camera/scanning UX.
This repository implements the Apache Cordova Camera plugin, which provides a cross-platform interface for accessing device cameras and photo libraries. The plugin supports Android, iOS, and browser platforms, allowing developers to capture images, select from galleries, and manipulate images (resize, rotate, etc.) through a JavaScript API. The architecture follows Cordova's plugin pattern with platform-specific implementations in Java (Android), Objective-C (iOS), and JavaScript (browser). The plugin handles image processing, EXIF data handling, file URI management, and permission handling across platforms. It returns images as either base64-encoded data URIs or file URIs, with appropriate handling for memory management and platform-specific quirks.
