How to Become Flutter Expert?
Hello World, I am Bishworaj Poudel, While writing this article, I developed more than 10 applications using flutter and also working as project manager for various projects. I am using flutter from its beta version. In this article I will share path to become flutter expert.
Flutter is software development toolkit from Google for building android, iOS, web app, desktop app from single codebase. Lots of developers are already in flutter and opportunity is also very high.
Learn Basics of Dart Programming
Before starting flutter, you must learn basis of dart programming. If you already know C programming / Java programming / C# programming, then you can easily understand dart, because most of them are similar. If you don’t know programming then you can also directly learn dart. Make sure you will understand at least these topic of dart.
- Basic Hello World Program.
- Variables and Constants.
- Conditions and Loops.
- Lists and methods.
- Methods and types.
- Object Oriented Programming.
- Class and Object.
- Constructors.
- List of Objects.
- Async and Await [Advance topic but will help later].
These are the basics term, you must know because it will make your life a lot easier later. So give some time to understand this topic. You can watch dart videos in YouTube or purchase courses on Udemy or practice at your own to learn dart programming. Official documentation is available at https://dart.dev/tutorials . This will be the best source for you always because this is official docs.
Learn Basics of Flutter, Widgets
The second step is to setup flutter on your computer and start learning basics of flutter. It includes how to use widgets like MaterialApp, AppBar, Scaffold etc. Create a simple screen, add photo, text, radiobuttons, text field, slider, container, buttons etc. Also look at Row, Column, Stack, Listview, SingleChildScrollView etc. The more widgets you know the more benefit for you.
Good design is need, customers need app with good design. Now you need to design app so beautifully. So focus on designing beautifully. This will add value to your work. Also share your work on various groups, publish it on github and also get feedback from users.
Also get inspired from website like https://dribbble.com/ and know various designs. Implement such design to your projects too. Also try to make clone UI of apps that are available on your phone.
Learn Functionalities & Navigation
The next step is to learn functionalities on flutter, create two textbox and button. While clicking on button show the result on dialog box. Similarly create various pages like login page, dashboard page, about page etc and navigate to different pages.
Learn and explore packages

Learn Shared Preferences & SQFLite
For simple and easy local storage you need to learn about shared preferences, which stores data locally in app. If your application is big then you must think about SQFLite, which is local database where you can use SQL commands. Now you can create apps which runs offline perfectly.
Learn State Management
Main job of UI is to represent the state, In most of the production level most of the applications are built with state management. Data passing becomes easy and code will be more readable. In coming article I will cover state management in details. Some popular state management solutions are:
- provider
