Q. Why should I learn Flutter?

Flutter is a cross-platform app development framework. Originally, iOS apps and Android apps had to be developed using different languages and different frameworks, but Flutter can be released on both platforms with a single source code. So you can save a lot of money and time when developing an app. In addition, it is a framework developed by Google, and Google is pushing it a lot these days, so it is a framework with a promising future, so it is good to learn about it.

Q. Is it definitely better to learn Flutter than React Native or Native?

Every framework has its pros and cons depending on the situation and purpose, so the answer to this type of question is always 'NO'. Flutter can release apps on both iOS and Android platforms very quickly with a single source code, but it still lacks many libraries compared to Native and is slightly behind in completeness. React Native has the advantage of using Javascript, one of the most popular languages in the world, and because it has been around for a long time, it is still more popular than Flutter.

Q. I have never learned programming before. Can I still take the course? Is it okay even if I am not a major?

Many people have successfully completed their first programming in their lives through my YouTube videos. Even if it is not Flutter, all programming has a considerable barrier to entry for beginners, but in this lecture, I have tried hard to lower the barrier to entry as much as possible. First, watch the Dart language lecture that is open to the public for free and check the difficulty level. If it is difficult, get help from the official Code Factory community.

💬 Code Factory Kakao Open Talk

If you purchase the Flutter course, you can join the Code Factory Discord server Flutter Premium channel! If you join the Discord server and send me the email you purchased the course with as a message, I will register you in the Premium channel! If you join the Premium channel, all questions will be answered with priority!

Q. Is this a completed lecture?

Currently, the course structure is suitable for the purpose of escaping from the beginner level . Flutter is planned to be divided into three difficulty levels: beginner, intermediate, and advanced, and UI, simple popular library usage, etc. will all be added to the beginner course. There is still a lot of knowledge left to convey to you, so please look forward to it!

Q. Do I need to have an Apple Mac?

You can follow the lectures on a Windows computer, but you can't build iOS apps. That's because Apple designed iOS apps to be built only on Macs, Apple's operating system. Flutter is very consistent across platforms, so if you code while looking at an Android screen on a Windows computer, you can think of the same app as the same code when you build it on iOS later. If you want to distribute it, I recommend buying an old MacBook that's compatible with Flutter.

Q. Do I need to have good computer specs?

Since it is easier to develop if you run a simulator/emulator, if your computer specs are too low, it may run slowly. If your computer specs are low, I recommend coding using an actual device! The required specs may change from time to time, so I will leave a link.

Q. Flutter installation fails.

To become a good developer, the ability to isolate and solve problems is also very important, so try hard and if it doesn't work out, 💬 Code Factory Kakao Open Talk Please contact us!

Q. There is a problem with the video.

For questions related to video playback and internet communication, please contact Inflearn. If the order of the video is wrong or if there are parts that are difficult to understand due to poor editing, please contact us directly through Open Talk. I will make improvements as a top priority and upload them again! I also check several times, but there may be mistakes because I manage so many videos.

Q. To what extent does the class cover the content?

I've tried to cover everything you need to know to build a UI in Flutter. Additionally, I plan to include simple front-end database management, network requests, and basic state management.

What's currently planned to be added

• Lecture on HTTP requests (using Dio and Retrofit)
• Data management and simple caching using Hive
• Simple state management using Provider

Popular state management packages other than the Provider package will be covered in the intermediate course! (BloC, GetX, etc.)
In addition, if there is any knowledge or technology that you would like me to develop, please share it with me through various channels. I will actively consider it!

Q. Are there any tutorials on how to release apps on the Play Store or App Store?

We will add it to the beginner course. If you want to try it out before the course comes out, please check the guide on the official Flutter website.
