feat: Add KMP Product Flavors support

[therajanmaurya]

Summary

Integrate kmp-product-flavors (v1.0.0) for cross-platform flavor support that aligns with existing Android application flavors.

Changes

• Add kmp-product-flavors v1.0.0 to version catalog
• Create KMPFlavorsConventionPlugin for easy integration
• Add KmpFlavors.kt with centralized flavor configuration
• Configure demo/prod flavors matching Android application
• Add mavenLocal() for local development support

Features

• Cross-platform flavor support - Same flavor configuration across Android, iOS, Desktop, and Web
• BuildConfig generation - Flavor-specific constants accessible from shared code
• Automatic source set wiring - commonDemo, commonProd, iosDemo, etc.
• Aligned with Android - Uses same contentType dimension (demo/prod)

Usage

Apply to any KMP module:

plugins {
    id("org.convention.kmp.flavors")
}

Build with specific flavor:

./gradlew build -PkmpFlavor=prod
./gradlew build -PkmpFlavor=demo

List available variants:

./gradlew listFlavors

Generated BuildConfig

// Access from shared code
object FlavorConfig {
    const val VARIANT_NAME: String = "demo"
    const val IS_DEMO: Boolean = true
    const val IS_PROD: Boolean = false
    const val BASE_URL: String = "https://demo-api.mifos.org"
    const val ANALYTICS_ENABLED: Boolean = false
}

Test plan

• Build project with ./gradlew build -PkmpFlavor=demo
• Build project with ./gradlew build -PkmpFlavor=prod
• Run ./gradlew listFlavors to verify variant configuration
• Verify BuildConfig is generated in shared modules

Update Needed Before Merge

The mavenLocal() repositories should be removed from:

• settings.gradle.kts (pluginManagement and dependencyResolutionManagement)
• build-logic/settings.gradle.kts

Since kmp-product-flavors v1.0.0 is now published to Maven Central and Gradle Plugin Portal, production applications don't need mavenLocal fallback.

I attempted to push this fix but the branch protection rules prevented it. Please remove these lines before merging:

- mavenLocal() // For local development with kmp-product-flavors

---

Library published to:

• Maven Central: io.github.mobilebytelabs.kmpflavors:flavor-plugin:1.0.0
• Gradle Plugin Portal: io.github.mobilebytelabs.kmp-product-flavors:1.0.0

📝 Walkthrough

Walkthrough

Introduces KMP Product Flavors support by creating a new Gradle convention plugin (KMPFlavorsConventionPlugin) that configures cross-platform flavor dimensions and flavors with build config generation, alongside flavor configuration infrastructure and repository setup for local development.

Changes

Cohort / File(s)	Summary
Gradle Plugin Registration build-logic/convention/build.gradle.kts	Added implementation dependency for KMP Product Flavors plugin and registered new kmpFlavors convention plugin with id org.convention.kmp.flavors.
Flavor Configuration Infrastructure build-logic/convention/src/main/kotlin/org/convention/KmpFlavors.kt	Introduced KmpFlavors object defining flavor dimensions (CONTENT_TYPE) and flavors (DEMO, PROD) with data classes for dimension and flavor configuration, plus extension function configureKmpFlavors to apply flavors to KMP extensions with build config field support.
Convention Plugin Implementation build-logic/convention/src/main/kotlin/KMPFlavorsConventionPlugin.kt	Created new KMPFlavorsConventionPlugin that applies KMP flavors plugin and configures dimensions/flavors using centralized configuration, including helper function to infer BuildConfig package names.
Version Catalog gradle/libs.versions.toml	Added version entry for kmpProductFlavors (1.0.0) and library reference for KMP flavors Gradle plugin.
Repository Configuration build-logic/settings.gradle.kts, settings.gradle.kts	Added mavenLocal() repository to plugin and dependency resolution management in both build-logic and root settings files for local development support.
