NeoBrutal UI Components for Jetpack Compose

A modern Jetpack Compose UI library featuring Neo-Brutalist design principles with bold geometric shapes, thick borders, high contrast colors, and distinctive shadow effects.

Introduction

NeoBrutal-lib is a collection of UI components for Jetpack Compose that embraces Neo-Brutalism design principles:

• Bold, geometric shapes with sharp corners
• High contrast colors
• Thick borders and visible structure
• Distinctive shadow effects for a 3D appearance
• Monospaced typography
• Raw, unpolished aesthetic

This library provides ready-to-use components that follow these design principles, allowing you to create distinctive, eye-catching UIs for your Android applications.

Installation

Step 1. Add the JitPack repository

Add the JitPack repository to your settings.gradle.kts file:

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        mavenCentral()
        maven { url = uri("https://jitpack.io") }
    }
}

Step 2. Add the dependency

Add the dependency to your app module's build.gradle.kts file:

dependencies {
    implementation("com.github.zahid4kh:neobrutal-lib:1.0.9")
}
