Are you interested in mobile application development?
If your answer is yes, you are reading the right article! Maybe you don't know about Flutter yet, but don't worry – I wrote an article about what flutter is and why you should learn it this year.
Flutter is a free and open-source mobile UI framework created by Google and released in May 2017. In a few words, this allows you to create a native mobile application with only one code. It means that you can use one programming language and one codebase to create two different apps (IOS and Android). – What is Flutter and Why You Should Learn It in 2021
In this post, I share with you two types of content, free or paid. I tried to find excellent resources to support every type of learner (videos, courses, books, tutorials, and so on).
Before we start, I also wrote an article about whether you should you learn to code with paid or free content - and why? If you don't know what type of content is the best for you, I recommend that you read that article before reading this one.
So let's get started. I tried to explain each resource with a small paragraph. All information came from the description of the associated website. As you can imagine, I haven't tried all these methods. If you need more details, I invite you to visit the linked website.
