Introduction1:16

About Jetpack Compose (UI Framework)15:50
States and Recomposition16:09
Configuration Change & State Persistence11:56
Events and UDF (Unidirectional Data Flow)8:15
State Hoisting4:41
State hoisting moves state up to the parent in Jetpack Compose, turning text field components stateless by passing values and on value change handlers.
Layouts7:10
Explore jetpack compose layouts by using column, row, and box to position and measure child components, with vertical and horizontal arrangements, spacing, and alignment options.
Modifiers11:01
Lazy components12:00
remember() vs derivedStateOf()9:25
Explore remember with a key and derivedStateOf in Jetpack Compose, showing how dependencies trigger recomposition and how derivedStateOf reduces unnecessary recompositions in lazy lists.
Slot-based API's5:13
@Preview annotation4:28
Learn to use @Preview in Jetpack Compose to preview composables in Android Studio. Keep composables stateless and use multi-device previews with configurable name, size, locale, theme, and system interface.
Local compositions8:17
Explore Jetpack Compose's scaffold with top and bottom bars, tabs, and nested components, and learn local composition, including static composition local of and composition local of for authentication state.
Side effects8:17
Animations13:32
Explore Jetpack Compose animations, learning animated visibility, content transitions, enter and exit effects, and infinite transitions, plus practical use of animated content, size, and lazy list animations.
Theming7:49
Jetpack Compose theming defines colors, typography, and shapes for a consistent UI in light and dark themes. Learn to customize Material three expressive tokens and override component colors at runtime.

Navigation 3 Setup11:32
Koin DI Setup8:15
Generate Material Theme Colors6:24
ToDoTask model class5:09
Adding Icon/Image Resources5:38
InfoCard and LoadingCard components9:58
TaskCard component18:14
Fake Repository17:36
Develop a fake repository to test the home screen, introducing a generic request state sealed class with idle, loading, success, and error, plus a fake data source for tasks.
Display all tasks in a HomeScreen16:26
Task Screen14:44
Priority Chip selection6:49
Task ViewModel - Create/Update a Task22:10
Develop a task screen using a task view model and ui state to load, create, and update tasks with a repository, error handling, and snack bar feedback.
Add Swipeable behavior inside the TaskCard13:46
Learn to implement swipeable task cards in a multiplatform app with the Swipeable KMP library, enabling left dismiss for delete and right swipe to mark as completed.
Task Completion/Deletion implementation11:43
Landscape mode support13:25
Search Query implementation14:19
Filter by Priority implementation16:39
iOS Navigation11:17
Explore iOS navigation in a multiplatform Kotlin project, building a separate navigation graph for iOS using the navigation tool, with a nav host and nav controller.
Swap fake data with the real SQLDelight database19:41
Swap the fake repository for the real SQLDelight database by enabling Gradle dependencies, adding a task database, and wiring Android and iOS drivers to use generated SQLDelight APIs.

Description

In this course, you’ll learn how to build a beautiful, production-ready To-Do mobile app for both Android and iOS, from scratch using Jetpack Compose Multiplatform and Kotlin Multiplatform.

- No XML
- No duplicated code
- No outdated practices

Just one shared codebase, written in Kotlin, powering two native mobile apps.

If you’re new to mobile development, or you’ve built Android apps before and want to step into the future this course is designed exactly for you.

Why this course is different

Mobile development has changed. Today, you don’t need separate teams or completely different codebases to build Android and iOS apps.

With Compose Multiplatform + Kotlin Multiplatform, you can:

Share UI and business logic
Build native apps for Android and iOS
Keep your code clean, scalable, and easy to maintain

And that’s exactly what we’ll do step by step.

What you’ll build

Throughout this course, we’ll build a real-world To-Do application that:

Runs natively on Android and iOS
Uses Jetpack Compose / Compose Multiplatform for UI
Stores data locally using a local database
Supports Light & Dark theme out of the box
Is fully responsive in portrait and landscape
Includes smooth animations and polished UI
Follows clean architecture with MVVM
Is scalable, maintainable, and production-ready

This is not a demo app, it’s a solid foundation you can reuse in your own projects.

What you’ll learn

By the end of the course, you will confidently understand:

How Compose Multiplatform works under the hood
How to structure a Kotlin Multiplatform project properly
How composables work, their lifecycle, and recomposition
How to build custom reusable UI components
How to manage state and logic with ViewModels (MVVM)
How to persist data locally in a multiplatform-friendly way
How to handle themes, responsiveness, and animations
How to write clean, readable, and testable code

Who this course is for:

Android Developers
Android Designers
Anyone who wants to learn new way of Developing KMP Apps
Anyone who wants to learn more about Compose Multiplatform by working on a real project
Anyone who wants to keep up with the Latest API's for Building Android/iOS Apps
Anyone who wants to improve skills and stay up to date
