BlocKotlin

A Kotlin implementation of the Bloc pattern for building Android applications in a consistent, testable, and understandable way, using Jetpack Compose.

Inspired by the Dart Bloc library — a Kotlin port of the bloc package originally created by Felix Angelov for Flutter/Dart. The same event-driven state-management pattern, brought natively to Android with Kotlin and Jetpack Compose. See the BlocSwift project for the iOS/Swift counterpart.

Getting started

dependencies {
    implementation("io.github.sergiofraile:bloc:1.1.2")
}

import dev.bloc.Bloc

class CounterBloc : Bloc<Int, CounterEvent>(initialState = 0) {
    init {
        on<Increment> { _, emit -> emit(state + 1) }
        on<Decrement> { _, emit -> emit(state - 1) }
    }
}

Full guide, core concepts, Compose integration, and examples are in the README on GitHub.
