Using Gradients

Using gradients is super easy with Holi, just use GradientMixer and choose from various gradient brush generating functions.

1. Mixing two colors

   GradientMixer.bottomLeftToTopRight(MaterialColor.RED,MaterialColor.GREEN)

2. Mixing more than two colors

   GradientMixer.topRightToBottomLeft(
    listOf(MaterialColor.RED,
    MaterialColor.GREEN,
    MaterialColor.PURPLE)
    )

3. Reversing gradients

   GradientMixer.rightToLeft(FlatColor.CARROT,FlatColor.POMEGRANATE,reversed = true)

Holi's GradientMixer is a container for gradient (Compose Brush) generating functions. These functions act as wrappers around Compose's gradient generators so that you don't have to figure out offset values with their directions. The idea behind this gradient mixer is easy access to gradient building.

How to use

Holi is available on MavenCentral, declare maven central in your repositories and implement the latest version in dependencies.

allprojects {
    repositories {
        mavenCentral()

Lyricist - The missing I18N and I10N library for Jetpack Compose!

Jetpack Compose greatly improved the way we build UIs on Android, but not how we interact with strings. stringResource() works well, but doesn't benefit from the idiomatic Kotlin like Compose.
