ktheme is a Compose Multiplatform library written to provide material design 3 (MD3) based theme, with essential components to configure it.

• DynamicTheme support for Android (with Amoled).
• Material Design Color Scheme support for other platforms (You must provide a color seed).
• The theme settings persist over sessions (clientSide).
• Pre-assembled components for configuration.

1. Paste this code to your .toml file

[versions]

ktheme = "0.0.3"

[libraries]

ktheme = { module = "com.feraxhp.ktheme:ktheme-compose", version.ref = "ktheme" }

2. Then paste this other code into your build.gradle.kts in kotlin > sourceSets > commonMain.dependencies

implementation(libs.ktheme)

3. Sync Project with Gradle
4. Now you can add DynamicTheme { } anywhere in your project, here is an example on your App.kt

import com.feraxhp.ktheme.DynamicTheme

@Composable
internal fun App() = DynamicTheme { // base color default is: 0X4C662B, to change it call baseColor: Int 
  // Your KMP App content
}

5. Update settings

val dts = LocalThemeSettings.currentOrThrow // Provider

// Access Settings

val seedColor by dts.seedColor.collectAsState()
val secondary by dts.secondary.collectAsState()
val tertiary by dts.tertiary.collectAsState()
val error by dts.error.collectAsState()
val theme by dts.theme.collectAsState()
val useDynamicColor by dts.useDynamicColor.collectAsState()
val useAmoled by dts.useAmoled.collectAsState()
val style by dts.style.collectAsState()
val contrastLevel by dts.contrastLevel.collectAsState()
val extendedFidelity by dts.extendedFidelity.collectAsState()
val hasAnimation by dts.hasAnimation.collectAsState()

// LocalThemeSettings: Provides set-functions to change every theme Setting.

ktheme provides access to all the settings of the Dynamic Theme by accessing this 2 Composition Providers:

• LocalThemeIsDark: Boolean Use it to know if the current theme is light or dark, you can change the theme here without storing it.
