SHIPPED, NOT JUST TUTORIALS

Flutter Junction projects

Libraries and apps we actually publish, not just teach.

Every tutorial on Flutter Junction is backed by real code running in production. Here’s what that looks like on Maven Central, Google Play, pub.dev and the open web — open-source, versioned, and free to use.

Alpha Jetpack Compose

FormFlow Compose

Declarative forms for Jetpack Compose, without the boilerplate

A Compose UI layer that turns field state, validation and error messages into composables you actually want to write — built for native Android developers who want Flutter-style form ergonomics in Kotlin.

Alpha Engine

FormFlow Core

The validation engine behind every FormFlow field

Framework-agnostic form state, validators and orchestration logic, decoupled from any UI toolkit. FormFlow Compose builds on it — or drop it into your own View-based or multiplatform project directly.

Bank Book

A private, encrypted contact book for bank details and money owed

No more screenshotting BSBs and IBANs into WhatsApp. Bank Book stores everyone’s banking details — Australia, India, Nepal, the US, UK, Europe and 10+ more — with AES-256 encryption, a PIN-locked vault, and a running balance for money given or received. Zero cloud, zero ads, zero account required.

background_guard

Find out why your Flutter background tasks are silently failing

On real Android devices — Samsung, Xiaomi, Oppo, Vivo — background work gets killed by OEM battery optimizations with no error thrown. background_guard detects whether a task actually ran, diagnoses the restriction, and guides the user to the exact system setting that fixes it.
