A complete flutter roadmap with a detailed explanation
After working on multiple projects from scratch, optimizing an unoptimized code, migrating projects to null safety, and coming up with the solution when your packages break, here I am to provide a proper roadmap to learn flutter.
When we start learning any technology, we directly go to YouTube and search for tutorials related to technology. It is good practice to learn from YouTube but self-study 😆 is the best source of learning. Here you have to explore on your own and figure out if you face any difficulties. In the starting, it will be difficult but definitely it add lots of advantages in the future.
So if we have a proper roadmap to learn any technology, it will help us to learn it fastly and properly.

1. Things you want to learn to build the flutter application.
While working on the application, we need to understand which things are necessary for the implementation of the application. Which programming knowledge you required? We also need to understand what are the pros and cons of using flutter. How flutter is different and many other aspects of using flutter.
To understand and get all the answers to the above question read an article by clicking on it.
2. Dart basic concepts to keep in mind while developing the application.
To build an application using the flutter framework, we need to learn dart programming. We should get clear all the concepts of the dart while working on the flutter application. As a beginner, we should get clear with the concepts like what are the data types, loops, functions, etc available in the dart. Also, use the dartpad to practice the dart.
Learn more about the dart concepts which are necessary to build an application as a beginner by reading the article.
3. All about the flutter basics you want to learn.
Flutter is all about widgets. Widgets are something that is available on the screen. It is visible to the user and it is part of the UI. We must aware, of how to use widgets properly. We need to understand what type of widget, we need to build something. What type of widget do we need to perform any action? It is also necessary to understand how to customize the widget for reusability purposes.
Understand as a beginner which widgets you should be aware of by reading the article in detail.
4. Explore the navigation in a flutter.
An application consists of multiple screens to display the information to the user. Navigation is an important part of the and also it is necessary to provide navigation between the screen so the user will be able to move from one screen to another screen. In flutter, we use Navigator to move between the screens. It has different methods to move between the screens.
In flutter, we can also pass data to new screens using different methods of Navigator which can be explored by reading the article.
5. Understand API integration in a simple way.
API integration is the most important part of the development of the application. While working on the application, we need to fetch data through the server and display it on the screen or we need to delete/ update the data which is available on the server. It is necessary to understand to connect the application with the server and perform the necessary action.
In flutter, we use the HTTP package for API integration. There are also other packages but HTTP is commonly used.
Understand the small demonstration of API integration using the HTTP package by clicking on the article.
6. A detailed explanation of storage used in a flutter.
When we develop an application there may be chances that we have to store a small amount of data locally. This data may be like user information or any other kind of information. It is not good practice to make an API call for a small of data that can be scored locally and make use of it.
Flutter provides us with different packages to store a small amount of data like SQFlite, SharedPreferences, Hive, FlutterSecureStorage, etc. which are used to store data locally.
Click on the article to understand how to use shared preferences and sqflite in detail with an example.
7. Manage a state using a provider package in a simple way.
State management is the most discussed topic in flutter development. As a developer, we should always be aware of how to maintain the state of the application. In flutter, we have lots of packages which is used for state management purpose like Bloc, Provider, Getx, MobX, etc. But it is always necessary to start with an easy one like Provider.
Learn more about state management using a provider package with a simple example.
8. Explore some animations used in a flutter.
Adding animation to the application is very useful to make it more engaging. Flutter provides varieties of animation support that can be implemented easily. In flutter, we have implicit animation and explicit animation. Implicit animations which are implemented using animated widgets and explicit animation are used to animate the widget according the requirement.
Check the article to understand some of the animation used in the flutter with a small example.
9. All things you need to know about pubspec.yaml file.
It is the most important file of the application. This file is auto-generated when we create the flutter application using the flutter create command. This file contains all the metadata of the application. It is mainly used to add assets to the application and use external libraries in the application.
Learn more about the pubspec.yaml file in detail by checking the article.
10. Learn the testing in a flutter with a small demo example.
Before launching any application we always wanted to make sure that the application is working properly or not. So it is always necessary to test the application. Flutter provides us to automate the testing in three different manners. such as Unit testing, Widget testing, and Integration testing.
Unit testing is used to test the function or method with a different condition. Widget testing is done to test whether the widget has been displayed properly or not. Integration testing is used to test the entire application.
Learn more about the testing by reading an article with a basic example.
Let me know in the comments if I need to correct anything. I will try to improve it.
Clap if you like the article. 👏
