Usage

After you integrated the KvColorPallet-Android library, you can consume it as follows.

Basic Usage

If you wants to consume basic features in KvColorPallet then use singleton instance as follows. This singleton instance allows consumers to access following basic functionalities.

// Generate alpha color schem of given color
KvColorPallet.instance.generateAlphaColorPallet(givenColor: MatPackage().matGold.color)

// Generate mat color schem of given color
KvColorPallet.instance.generateColorPallet(givenColor: MatPackage().matGold)

// Generate theme color pallet of given color
KvColorPallet.instance.generateThemeColorPallet(givenColor: MatPackage().matGold.color)

Advance Usage

If you wants to use KvColorPallet-Android to generate your theme color pallet when your application start-up, then you have to initiate the library in Application level. To initiate you have to pass one base color that you think your application will use. Use following code to initiate the library package.

override fun onCreate() {
    super.onCreate()
    // Initialize the kv-android-color-pallet
    KvColorPallet.initialize(MatPackage.MatDGreen)
}

This initiation create a color set for a theme using the given color at the initiation. This generated color set available for light and dark theme variants.

In this KvColorPallet.appThemePallet you will have following color attributes.

Attribute	light-theme	dark-theme	Description
.base	original	original	This is the base color given by the user.
.primary	available	available	Suggesting primary color. This color can use for buttons, major component etc.
.secondary	available	available	Suggesting secondary color. For any the secondary components which should not use by primary color.
.tertiary	available	available	Suggesting tertiary color.
.background	available	available	Suggesting background color.
.onPrimary	available	available	This is the color you can use on any component use primary color.
.onSecondary	available	available	This is the color you can use on any component use secondary color.
.shadow	available	available	This is the color for your shadows.

Use generated theme

As mentioned above, according to the initiation color, that generate the color set for light and dark them. In your Jetpack Compose project, you can assign generate color set the your application theme.

    // Access the generated theme color set from kv-android-color-pallet library
    val theme = KvColorPallet.appThemePallet

    // Generate application light theme using kv-android-color-pallet light colors
    val themeLight = lightColorScheme(
        primary = theme.light.primary,
        secondary = theme.light.secondary,
        tertiary = theme.light.tertiary,
        background = theme.light.background,
        onPrimary = theme.light.onPrimary,
        onSecondary = theme.light.onSecondary
    )

    // Generate application dark theme using kv-android-color-pallet dark colors
    val themeDark = darkColorScheme(
        primary = theme.dark.primary,
        secondary = theme.dark.secondary,
        tertiary = theme.dark.tertiary,
        background = theme.dark.background,
        onPrimary = theme.dark.onPrimary,
        onSecondary = theme.dark.onSecondary
    )
    
    // Generate the color schema
    val appColorScheme = when {
        darkTheme -> themeDark
        else -> themeLight
    }

    // Assign the color schema to the team.
    MaterialTheme(
        colorScheme = appColorScheme,
        typography = AppTypography,
        content = content
    )
