Become a Flutter Developer from a BTech Background

Follow this 12-week plan to switch to a Flutter developer role. You will learn Flutter basics, build a full app, and master state, forms, testing, and deployment. All steps are simple and beginner-friendly.

Weekly Hours: 10
Estimated Weeks: 12

Phases

Foundations: Dart and Flutter Basics

Start by learning the Dart language and Flutter basics. You will understand how to write simple code and run your first app. This phase helps you get confident with the tools and concepts needed for app development.

3 weeks

Learn Dart language basics
Understand Flutter framework setup
Run your first app
Explore UI widgets

Write Dart variables and functions (DartPad)
Build simple UI widgets (Text, Button)
Use Flutter command line (flutter doctor)
Debug basic errors (console logs)

Official Dart Language Guide
Flutter Documentation
Beginner Dart Tutorials
Free Online Flutter Courses

Build and run a basic Flutter app (shows Hello World)
Complete a Dart mini quiz (10 questions)
Document setup steps with screenshots
Submit app code for review

Intermediate: Navigation, State, and UI Design

Dive deeper into app structure. Learn navigation between screens, manage user input, and control app data (state). Design clean and simple interfaces.

3 weeks

Learn screen navigation
Manage basic app state
Handle user input (forms)
Design with layout widgets

Add navigation routes (Navigator)
Build forms (TextFormField, validation)
Work with state (setState, simple state management)
Create custom layouts (Column, Row, Card)

Flutter Navigation Guide
Form Handling Tutorials
Layout Widget Gallery
Design Guidelines for Flutter

Create two connected screens (with back and forth navigation)
Build a form with validation (name and email input)
Demo a simple state update (increment counter)
Document UI decisions (with screenshots)

Advanced: Data, Testing, and Project Structure

Learn how to fetch and display data, write tests, and organize code well. Start integrating all Flutter core concepts and prepare for real application work.

3 weeks

Read data (from API or local source)
Write unit and widget tests
Follow project folder structure
Add basic error handling

Fetch sample data (http package)
Write basic tests (flutter_test)
Organize code into screens and widgets
Handle loading and error states

HTTP Package Guide
Flutter Testing Guide
Sample Project Structures
Testing Tutorials

Display a list from fetched data (API or JSON file)
Complete at least 3 widget tests (flutter_test)
Show error message for failed data load
Submit full project structure diagram

Showcase Project: To-Do App with Depth

Apply all skills to build and refine a To-Do app. You will include navigation, input, state, data persistence, simple tests, and deploy your app. This project will be your portfolio piece.

3 weeks

Build To-Do app with add/edit/delete tasks
Use local storage (save data)
Test app flows
Document and deploy app

Save data (shared_preferences)
Write integration tests (flutter_test)
Document features (Readme)
Deploy to web or emulator

To-Do App Tutorials
Local Storage Guides
Flutter Deployment Docs
GitHub for Hosting

App supports add, edit, delete tasks (with local save)
At least 5 passing tests (unit/widget/integration)
Readme includes setup, features, screenshots
App deployed (web link or emulator demo video)

Weekly Plan

Week	Focus	Why	Tasks	Deliverables
1	Start with Dart basics and environment setup	You need Dart and Flutter tools ready before you code.	Install Flutter SDK (official link), Set up IDE (VSCode/Android Studio), Try DartPad online exercises, Write sample print statements	Screenshot: flutter doctor result, DartPad code link
2	Learn basic Flutter widgets and layout	Widgets are the building blocks of any app.	Build app with Text and Button widgets, Use Column and Row for layout, Change widget styles, Try hot reload in IDE	Basic app with styled text and button, Screenshot: app running
3	Combine widgets, handle simple state, and debug	State makes your app interactive.	Create a counter with setState, Add multiple buttons, Use console to debug errors, Write a summary of findings	Counter app with two buttons, Debug log with notes
4	Learn navigation between screens	Apps often need more than one screen.	Add a new screen to app, Use Navigator to switch screens, Pass data between screens, Test navigation works	Two-screen app demo video, Code with screen navigation
5	Work with forms and user input	Forms let users send information.	Add a form with TextFormField, Set up basic input validation, Show error messages when needed, Save form data to a variable	Form with working validation, Screenshot: error message in app
6	Design app layouts and custom UI	Good layout improves app look and feel.	Use Card widget for task display, Build a task list layout, Align elements with Padding and Center, Document chosen colors and fonts	Task list screen screenshot, Short style guide
7	Fetch and display data in your app	Apps often need to show real data.	Try http package to fetch sample JSON, Display data in a ListView, Handle loading states, Log errors if fetch fails	ListView that displays API data, Sample error message screenshot
8	Refine app structure and write simple tests	Good structure and tests make future changes easier.	Split code into widgets and screens, Write unit test for a function (flutter_test), Document folder structure, Run test and fix failures	App folder diagram, Passing test screenshot
9	Save data locally and prepare main project features	Local data makes your To-Do app useful.	Use shared_preferences to save tasks, Test add/edit/delete of tasks, Plan app features (on paper), Update app to use local save	Tasks saved after app restart, Feature plan document
10	Add more app features and improve error handling	Robust apps handle user mistakes and provide more tools.	Add edit and delete task features, Show and clear validation errors, Add filter by task status, Test behavior with wrong inputs	Working edit/delete in app, Error handling demo
11	Write more tests and document your project	Tests and docs make your work trusted and sharable.	Write widget and integration tests (flutter_test), Collect app screenshots, Write Readme with setup steps, List app features and known bugs	3+ passing tests, Readme file with screenshots
12	Deploy your app and share your achievements	Deployment proves your app works and is ready for jobs.	Deploy app (Flutter web or emulator video), Create a GitHub repository, Share link with peers/mentors, Get feedback and plan improvements	Public project demo (URL or video), GitHub repo link
