Great video. One note: at 8:54, you mention that it's easier to extract code from nested widget trees in React Native (using methods) than in Flutter (using widget creation). However, in Flutter it is also possible to use methods, e.g. `Widget build(BuildContext context) { ... } _buildSubtree() { ... }`

[@epicsheepgamer7002]

I have been using Flutter since about the start of the year and I must say: I like it! I agree about the long widget trees though. They are a pain! For any new Flutter user, it is good practice to extract widgets from a widget tree and to keep widget trees as simple as possible. Also, try and keep your extracted widgets as modular and neutral as possible so that you can use them in a variety of ways/places. Nice video man! Very informative :D There is one thing I disagree about though: At 9:23 you stated that it is a goal to run an app at 60 frames, which is not always 100% good for mobile. Firstly, for something like a store catalogue app, you will never need more than 30 frames. Secondly, long ago when I made a mobile game with Unity as part of my varsity project, we were told to limit mobile apps and games to 30 frames (in most cases) as usually with mobile games 60 frames are not necessary and will only nuke the battery. Maybe you used 60 frame rendering only as a performance measurement?

[@NymezWoW]

Flutter would be awesome if it didn‘t use Dart. On paper Dart as a language isn‘t bad. But you have to invest into a language that basicly is not used for anything apart from Flutter apps. That means there is going to be less libraries, developers that you can hire, etc. The ecosystem of Dart is always going to be very lackluster compared to any of the big general purpose languages. And no matter how similar to existing languages it is or how easy to pick up it is, it is a new language that you and everyone else in your teams needs to learn just for the sake of being able to use Flutter. Just one good Application framework isn‘t nearly enough to justify a new language that otherwise doesn‘t bring any advantage or improvement over existing languages on the table.

[@alexander_farkas]

@@NymezWoW I learned it in 2 days, when I started, lol. Also, why would you need to use dart anywhere else? I've only used 4 languages in my flutter mobile dev career (2 years) - rust, kotlin, swift and dart. And yes, I never used them outside of mobile dev. So what's wrong with dart being single-purpose? It's pretty obvious that you should use react native, if you're fullstack. But if you're not - why not to learn new language, which you're going to use 95% of the time.

[@rayhaanalykhan]

Buhahah

[@themisir]

I've myself created the same application in both frameworks. What I learned from that experience is, if you need too much interaction with the native platform js bridge will make your code a bit slower. So what does that means? For example if you want to animate something with javascript, you'll have to send message through bridge which is going to create bottleneck to your performance but in flutter side your draw calls doesn't go through any sort of pipeline so it will not suffer same issues as react native. But in flutter you'll experience issues regarding user experience especially for text input boxes. Additionally to that native views doesn't work well with flutter widgets and sometimes feels cranky. In react native because it uses native views for displaying content you'll lose some level of customization. For example when I checked you couldn't add colored drop shadow under the view on android. Also because react native uses native views you can't just create your own canvas and draw on it (probably possible with 3rd party plugin). But in flutter if something is missing or possible, you can create your own widget from ground up using from low level to high level APIs depending on your requirements. The main reason of my switch from react to flutter was: - Dart (I prefer type safe languages over dynamic ones and yes I know typescript but it's not static typed as dart. You can't do runtime type checks) - Level of customizability (It took me less time to get even better translation of design our UI designer drew into screen) - The app didn't needed as much as native look-n-feel - I didn't wanted to learn Redux, and struggled with react state management. In flutter if I can't understand a concept, I can easily ctrl+click on the function or class and deep dive into the source code to find out what's going on. But for react native when you ctrl+click you'll either end up in typescript definition or some minified javascript file.

At 7:30 you mention that dart unlike typescript does provide null-safety. Typescript also has the option to compile time check for nulls though. Strict mode just hast to be turned on

[@Ked_gaming]

Strict mode protects against the any type, you can still have null/undefined values, it doesn't provide null safety

[@Gorgggg]

@@Ked_gaming strict mode actually keeps you from making errors in a lot of ways. There are are indeed a few things related to any (like noImplicitAny), but also quite a few related to initialisation and nullability, the most important one being strictNullChecks, but also strictPropertyInitialization and many more help against possible null values.

[@salmanpatrick]

I'm chosing React Native because I'm well settled in react ecosystem . I'm used to it and I love it. And I think I can build android apps much quicker in React Native as it's all the react js with lil bit different styling and semantics. So learning another language and whole another framework can be waste of time when there would be no significant difference in the product for the end user as the fireship said. So I think RN is the perfect choice for the devs coming from the react/js environment. And with expo , it's much better and evene easier . Life is too short. Make things simple and save your time. And avoid unecessary complexity.

Being consistent and only having one choice makes the dev more efficient as he goes.

Great video as always! I totally agree that refactoring is more difficult in Flutter. Changing the UI sometimes feels like starting from scratch again. On the issue of deeply nested widgets, if one child widget starts to get larger, you can always separate it in another function or create another widget for it. And to share data between widgets, you can use state management tools like Provider.

That was a messy, unreadable code right there. He should have refactored it and done proper, clean, thoughtful abstractions

[@zachwright6528]

You don't even always need a new widget. Just create a function to pull parts out. You can have some SUPER readable code in this way.

[@jimmorrison2657]

@@zachwright6528 I was thinking the same, mate. I am a Flutter programmer, and I do this. My code is never deeply nested. But I do worry that less experienced/disciplined coders will be tempted to write deeply nested code with Flutter. Code that I will then have to try to read. It's not just about the code I write myself but also about the code other people write.

I noticed a few small errors, for example pressing R for React Native does a complete reload and not a hot reload (the partial reloads just happens as you save the files), but nice comparison overall. After seeing how nasty those widget trees get on Flutter I'm glad I am on React Native!

Been using react native with expo framework. Developing on a M1 MacBook Pro, and developing Android apps using Expo has been very easy. The struggle of configuring and setting up an Android Emulator with Android Studio on a M1 is too much of a hazzle for me. Else I'd try out Flutter aswell.

As a js developer I can say that dart is simliest language I ever learn. 95% similar to typescript. But better. So switching to dart is not as Big problem as every video says. But Flutter technology is one step higher technology of ui styling and easy of achive amaizing results on ui. I tried react and create couple apps. Learning was not as fast.

[@santiagozapata9056]

Keeping in mind that there are efforts out there to bring Skia to React native, so hopefully performance differences between Flutter and React native won't be as "noticeable"

[@lucccar]

I don't think there's a need for this anymore. In the last react native cofnerence in september, they announced the Fabric architecture will be the standard for all react components and most of if built in C++, , eliminating the bridge and the memory sharing between the two threads.

[@eng3d]

@@lucccar So we could wait for it, or jump straight to Flutter/Dart. Also, since React is friendly with their updates and nothing is broken (of course I am joking), so the election is obvious.

Flutter is moving to a better rendering Engine will most like won't use Skia. :P

@@_dinesh Does not change the fact that state of the art arrived to react native, aside from that, as stated by the man behind react-native-skia react-native-impeller could be a thing as they keep an eye on it, still you could say react-native already used skia because that's how android renders items on screen

[@joaobonsegno126]

I don't have a nice sensation with Dart. I think the deep nested components and the verbose syntax makes the code much less readable or intuitive, so I really prefer looking into React Native codes. And when an app gets bigger, more readable codes can ne significantly important, so I kinda prefer RN currently

[@Paarthk]

You mention that Dart has strict null checking as an advantage it has over TS + React Native, but TS also has strict null checking. Is there something that Dart does better there?

Just watching this video, knowing little about either tool, Flutter seems like the better choice. Sure, you have to learn a "whole new language", but when the language is syntaxically familiar, that's not much of a hurdle.

[@FurqanaFathuzzaman]

Came from C# background, and yeah, no significant challenges in learning the language. It's definitely easier to learn dart than js in my case. The learning curve came from the Flutter itself, especially the hundreds kinds of state management

[@Troyx_]

For anyone interested: the problem of nesting in flutter is trivially solved by the "builder functions" - local methods that build separate segments of the component, and are called from the main build method (or other builder functions). This is of course when splitting a widget into multiple smaller widgets is not worth the effort.

[@YoussefElBehi]

It's a bad practice to separate in methods. You should always separate in classes

@@m3hdim3hdi He's a Flutter dev so he was a bit biased. But I told him my project requirements (I needed real-time geolocation and push notifications, always-on display like google maps) and he told me did something similar, and Flutter works just fine. If you're trying to prototype and ship an app fast then Flutter is better since it has many widgets built by google engineers for most of the tasks you need. Why reinvent the wheel when Google devs are doing it. I'm a react developer so I was a bit biased for RN but I have to give it to Flutter.

[@tabliqatchi6696]

[@MrTurbo_]

From having used both for multiple months at work i can say with confidence I'd take flutter over react native in a instant, debugging in flutter is even easier than depicted in this video and 10 times nicer then debugging react native, almost never having runtime errors is also addicting, I've built multiple pages with state without running it once and it would just work first time, it's really stable, no updates breaking that one component, if you need a component it probably is already built in, the docs are a 10 out of 10, also the vscode tools are the best, also better than shown in this video and the cherry on top is you can compile for Android, iOS, macos, windows, Linux, web and even will work for making something like the ui for a coffee machine with a raspberry pi, if you know flutter you can built anything ui related you want
