SweetMeSoft KMP Library
Table of Contents
Project Summary
SweetMeSoft KMP Library is a unified, multi-module Kotlin Multiplatform SDK designed to streamline cross-platform application development across Android, iOS, and Desktop platforms. The project provides basic UI components, forms inputs, native map visualizations, device-level location helpers, and standardized architectures for application screens and ViewModels. It abstracts platform-specific APIs and boilerplates into a common set of APIs.
Functionalities
- Architecture Foundations: Implements standardized screen wrappers and lifecycle-aware view models for handling asynchronous operations.
- UI Controls: Provides custom interactive elements including password fields, search inputs, and standalone picker dialogs.
- Maps and Geolocation: Embeds native map views, manages overlay elements such as markers and polylines, and facilitates location acquisition services.
- Theme System: Generates color schemes dynamically utilizing base branding metrics conforming to Material Design specifications.
- Network Client Wrapper: Standardizes HTTP calls with support for dynamic loading states, headers, and authentication.
- Demonstration Application: Contains a showcase application for verifying and exercising all library modules on target platforms.
Libraries and Dependencies
Core Implementation
The workspace compiles common Kotlin codebase into platform-specific targets. Android artifacts compile into Java Virtual Machine bytecode compatible with Dalvik/ART runtimes. iOS compilation utilizes the Kotlin/Native LLVM-based compiler to generate Apple Frameworks (xcframework binaries) consumed directly by Swift or Objective-C runtime environments. The application utilizes Compose Multiplatform to draw layouts directly onto native canvas targets, bypassing heavy native view hierarchies while maintaining natural platform responsiveness.

Design Patterns Implemented
- Model-View-ViewModel: Architecture separating state declarations inside ViewModels from structural UI declarations in Compose screens.
- Adapter Pattern: Unified maps component wraps the platform-specific Google Maps API on Android and MapKit API on iOS behind a single common interface.
- Bridge Pattern: Declares platform-specific APIs inside the common main layer and connects them to actual implementations inside the androidMain and iosMain folders.
- Service Locator: Used within the navigation engine to lookup active screens, viewmodels, and navigator states.
- Observer Pattern: Employs Kotlin StateFlow and SharedFlow to push state updates asynchronously from ViewModels to Compose layouts.
Configurations
The build configuration uses standard Kotlin Multiplatform Gradle configurations. Settings files define the modules in scope. The version catalog defines standard third-party library versions, plugins, and group names. Common source sets handle standard multiplatform business logic and layout scripts, while platform-specific source sets (androidMain, iosMain) configure platform-dependent libraries.
Integrations
- Android Google Maps SDK: Integrates Android map layouts and native marker structures.
- Apple MapKit: Renders map layouts and overlays on iOS targets.
- Android Location Services: Accesses system location providers for GPS reading.
- iOS Core Location Framework: Hooks into iOS native location providers.
