We'll answer your questions in advance 💬

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.

(2) Images shared for lecture purposes

The images I provide in the lectures are images that I purchased for a fee. I purchased the rights to create and distribute my works, but you must never distribute the images to others or on the Internet! Do not use the images for purposes other than studying, as this may result in legal issues due to copyright infringement.

(3) How to ask questions

One way to really improve your skills quickly while learning programming is to learn how to ask the right questions. Because of the nature of programming, it's hard to look at the entire code. So if you upload the entire code of the widget that's causing the problem and say, "This doesn't work!", it's hard for me to answer.
When asking a question, if you organize it well in the three steps below, we can communicate and answer you much faster!

1️⃣ How do I think it should work?
2️⃣ How it works now
3️⃣ Where exactly is the code and what problems are occurring (if there are even examples👏)

(4) Additional confirmed lectures

  • Fine dust measurement app using government API (complete)
  • State management using the Provider package (refer to Code Factory Intermediate Course Riverpod [Provider 100% compatible])
  • Using the Hive Database (Completed)

    Finally, I've heard it all. I just listened to it without any knowledge of Flutter, but I got the feel of screen layout and drawing. I still don't know what widgets are needed to create a screen, and I don't know the names of the widgets, but if I know the names of the widgets, I think I can draw them using documents or Googling. In additional lectures or intermediate lectures, I hope there will be examples of actual apps that structure functions that are often used in real apps, such as splash screens, onboarding screens, logins, and http communications, in one app??

      Hello! I'm working on a project with exactly that structure. It looks like it'll be the intermediate course you're looking for! In addition, if you take one more course on deep state management, caching system management, data modeling, Optimistic Response, Pagination, etc., I'll make sure you can grasp REST API integration.

    At first, the term context is used a lot, but even if you have prior knowledge and say you will explain it later, I think it would be better to just briefly touch on it at the beginning. It appears constantly from the beginning to the middle of the lecture, but it is frustrating that you just pass it over saying you will explain it later. Of course, you can Google it and find out for yourself, but I am leaving a few words here for students who cannot.

    • codefactory

      Hello, I'm sorry for the frustration. Context means context in Korean. You can actually use context to find out the current state of the widget tree. So, if you use Theme.of(context) and MediaQuery.of(context), you can get the Theme or MediaQuery located at the top of the widget tree!

    In most online lectures, the instructor talks on the screen and the students are busy following along, but in this lecture, the instructor directly helps with error corrections and corrects lecture errors through the online community. In that sense, I was able to learn as effectively as in offline lectures. And if I'm lucky, I can hear the instructor sing live. It's really the best!

    I am a developer with 17 years of experience. I recommend this course to those who are new to Flutter, and it is also very useful for practical projects. There is no better course than this one. In my case, I studied for about 3 years through books, YouTube, and lectures given by other instructors, but this is the real deal. Those who have some basic knowledge of Flutter can start with the last part, the fine dust app. It is explained so clearly that you won't regret the tuition, and it feels like it satisfies the basic knowledge and development tools that a developer needs. I am a developer with 17 years of experience, but I still have a lot of shortcomings, and this course has really helped me a lot. I look forward to the sequel. Please don't rush it and keep the quality as it is now^^

    Hello Code Factory. I am Flutter Nubi who used to live in Canada and asked about the possibility of overseas employment before taking the course. While taking the course, I started working on several side projects and studied iOS separately, so I delayed completing the course, but I finally finished the studies I had put off. I have taken many Flutter courses in Korean or English, but I think Code Factory's approach and method of explaining things are by far the best. I haven't gotten a job yet, but thanks to Code Factory, it has become much easier to develop with Flutter, and I have a better understanding of why and how the code is written and where to look for it. Whenever people around me say they want to learn Flutter, I always recommend this course to Koreans. Thank you for making such a great course. After my busy schedule, I will try to diligently study the intermediate course while preparing for employment! Thank you!!
