Flutter is a UI toolkit developed by Google that allows building mobile, web, and desktop apps from a single codebase. It compiles code to native languages, has wide platform support, great documentation, and a large community. This document outlines a roadmap for learning Flutter as a pro in 6 steps - starting with Dart basics, UI development, API integration, databases, state management, and project structure. Prerequisites include OOP concepts and version control with Git.

1. Roadmap to learn Flutter like a pro
Learning any technology/language takes time and patience. Don’t stop in middle, don’t
start from advance and don’t compare your journey with others!
Flutter is one of the most liked and adopted technology in the current IT Industry. But why is it so? Why
is Flutter trending so much? There are other frameworks too, then why Flutter? So in this article, let’s
first see what flutter is and why is it trending and then we will look at how to learn Flutter like a pro!
What is Flutter?
Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for mobile, web,
desktop and embedded devices from a single codebase. So in other words, if you make your apps or
websites using Flutter, it will be more beautiful and will be faster compared to other frameworks or
technologies! So why is Flutter getting so much popularity?
• Flutter compiles the code to the native language.
• Startups can easily adopt Flutter and create MVP.
• Wide platform supports (Android, iOS, Windows, macOS, Linux, Embedded, more coming soon!)
• Great documentation and ample resources available to learn
• Large and supportive community!
• OpenSource!

2. Roadmap to learn Flutter like a pro!
Step 0: Prerequisites
Before you start Flutter, you should at least know OOP Concepts. Flutter uses Dart language and Dart
uses OOP Concepts. So, the least would be to learn OOP Concepts in any language (Java preferred). It’s
always a good idea to learn Native Android so that you can understand Flutter more easily. Not a
compulsion, but a better way to explore. If you are a fresh grad, it’s your responsibility now to create a
portfolio or online presence to stand out from the crowd! So, learn GIT. Host your projects on GitHub,
no matter what project it is! Install Flutter in your system so that you can start your journey!
Step 1: Start with basics!
Dart is a wide language and will take time to master. Before jumping to apps, one should at least learn
the basics of the Dart language. If you already know Java, the transition from Java to Dart will be pretty
easy! Don’t directly jump to Flutter without knowing Dart. Few concepts that you should learn:
• Lists
• Map
• Lambda Function
• mixins
• await and async
Once you complete the basic dart concepts, feel free to explore Flutter.
Step 2: Get your hands dirty with UI Development!
Whenever we start a new language, we need the motivation to learn daily. When we first start with UI
development, it gives relief. When the screen of your app 1st pops on your device and it is as expected,
that is the time when you feel motivated! Also, there are many issues and errors a developer will face
when working with UI Development in Flutter. So what can you do or how can you do UI Development?
• Take any UI from Dribbble and implement the same in Flutter
• Create clone apps like Whatsapp clone, TikTok clone, etc.
Step 3: Learn API Calls
Once you feel confident with UI Development, you should start with learning API Calls. APIs will always
be needed whenever you create any apps. API calls can be done using different packages available like
http, dio, retrofit, chopper, etc. The basic one is HTTP and other packages are a wrapper over HTTP with
few more functionalities. You can choose any of them, but it's always good to start with http and then
any other packages. You can get many fake APIs to integrate with your app from:

Once an API is integrated and an API call is made, you need to parse that API Response into a model
class:

Working with APIs? The response usually comes in JSON format!

3. Step 4: Learn Database Integration
Databases are an integral part of any app. There will always be a need to store certain data from your
app. Some of the databases which can be used with Flutter:
• Firebase
• Supabase
• SQFLite (Local database)
• Hive (Local database)
• Moor (Local database)
• And many more…
Step 5: Learn State Management
State Management is one of the most important concepts in Flutter. When our app grows in size and
complexity, it becomes really difficult to manage the state of your screens and application. Let’s say you
want to pass data from Page 1 to Page 2. That’s easy. We can pass it during Navigation. But let’s say you
want to pass data from Page 1 to Page 5. In this case, state management is helpful! There are lots of
State Management techniques and packages available. But don’t stress yourself out! Use the one which
you are comfortable with. You can start with Provider as this is one of the basic State Management
Package.
Step 6: Learn Project Structure or Architecture
Maintaining a Project Structure is really important. It helps newbies to review the code quickly. It also
helps to trace the bug easily or add or remove functionality as and when needed without breaking the
current functionality. There are many predefined Architectures available like MVVM, MVC, TDD, etc.
These are really great and created after proper research. But they are not compulsory to use. You can
always create your own Architecture that is suitable for you and your team. Always remember to
maintain the following points with your architecture:
• KISS (Keep It Simple, Stupid!)
• Scalable
• Least inter-dependency between functionalities
• Code reusability
If your architecture satisfies the above points, it's good to go!
Note: This roadmap is created by me, others can have different views and strategies. Always use
whichever gives you the best learning!
