Complete GetX State Management | Flutter 

I'm mashing the "Like" button but it ain't incrementing enough! Great job as always. Keep it up! Proud of your amazing work.

I am starting up as a Flutter user and did some courses on the basic principles. However, I never felt good with all the types of page transitions and State Management solutions. All those guys(and Girls) use so many terms I have never heard of. THIS MUST BE POSSIBLE TO DO IT MUCH EASIER!!!!. That was what I was thinking after every complex explanation! THIS is the most straightforward solution for page transitions and, I did not notice that on the RU-vid title, also easy peasy State Management. This is awesome for a simple hobbyist who does not have a degree in programming.

Was looking for a good getx tutorial from ages. Thanks for the video. Really good explanation.

Wonderful work !! I will replace the multiple package with one , I hope get dive deeper in lazy , routes binding and localization (load locales files From json file & translate with plaure and args) , Thanks for this video

Amazing. Thanks for the video. It clarified a lot about Getx. I believe that like me, many would like to see how Getx would work with lists, forms, and everyday things that need to be reactivated. Thanks again for posting this content on your channel.

Best tutorial I have ever seen!

Best introduction to getx

Wow i never knew getx so simple... Until now I just kinda ignored it. Its so fast to get going... Thanks for this definately subscribed

Many thanks for the vid, and thanks to Jonny (& others) for some super work. I tried Flutter some time back and tore my hair out over state management. Now that it's this simple, I'll definitely retry Flutter. GetX makes it simple and elegant.

Really excited about it

Excellent video. Please use GetX to interact with an api (CRUD) thanks

Great job. easy to understand! best GetX tutorial I haven seem!

Great work! Keep it up

I love the series, the "workers" as reactions in Mobx and the "getter" has computed vars, all without using meta decorations! Bravo! I can imagine using computed vars to validate form fields! Awesome . the debounce is awesome. Just a recommendation to the Dev if he can make a worker like a filter, where the filter will override an observer value with a filtered value. Example: filter(count, (counter)=> counter > 10 ?10 :counter, active: true); filter(text,(text)=> _capitalizeFirst(text));

Really liked the video, there is a reason it has 0 dislikes xD Can you do GetX Utils next time like changing Theme and Locale, it has barely any docs about the Utils. That would be great!

Good job.. Its simple and easy to use.. One suggestion is zoom the editor bit more as it would be easy to follow.. Thank you..

how to keep app wise state of the application , for example when leaving the second page and going back to second page again it reinitiate the sum controller class with values 0 , what if we to keep the values even if the page is popped?

"The Jury Is Still Out": suppose I am building Book Library Web application, and I am reading book Id 123 on a page number 78. When I click "refresh" button in the browser, "state" gets lost because of application reload. How to maintain the state without hardcoding book Id and page number in the URL? [I think framework needs local and/or remote persistence store for this to work, and any claims "ABC state management implementation uses less memory than XYZ" are too far from real life requirements]

Great video, simple and very clear!

waiting for it !

Great video man 🔥, On to the point. I was frustrated with flutter state management & scoping. This GetX seems seems natural and less cluttered

Awesome, why your videos are always so good, to the point and perfect duration . What do you (Amateur Coder & whom so ever reading my comment) use most also considering writing unit test cases for business logic: -Riverpod -GetX -BLoC (stream controllers) -flutter_bloc -Redux Personally, I have mostly used flutter_block with state/event/yeild sort of architecture with every screen/page. Started getting in to River and GetX but really now with lot of choices getting into confusion...

Thanks for your hard work. Really. it's a good video for getx.

I'm so glad i found your channel! Is there any way you could make a video-guide, where we could learn how to display complex json-data from an api call using GetX?

There are a few things I want to say including some questions: 1) I’m using Provider with ChangeNotifier for an highly complex app. That many Provider classes cause a performance problem. (It is not seen but eventually it happens as shown in debugging tools.) Also using providers is difficult because of syntax and the need of context. The reactive side of the GetX, the Obx, may also cause performance issues since they are basically open streams. So I figured out that the best way for a state management is using the onUpdate side of the GetX. That way updates occur only on demand. The syntax is easy, no context and no calling the controller class inside the main build method of a widget class. 2) When using GetBuilder, what if we need multiple controller classes? In Provider package we have the MultiProvider package. It’s useful to wrap other widgets. GetX does need a wrap too. How can I depend on multiple GetX controllers inside the GetBuilder? (Maybe wrapping them over and over just works but is there a better syntax for readability?) 3) Provider package uses the closest provider class declared in the widget tree. I have post and profile screens in my app. (You can think it like Instagram where you can constantly navigate to a post than its user profile than another post than a tagged person’s profile over and over.) I use some of the provider classes as the logic controller instead of doing logic stuff inside the StatefulWidget. For example there is a ProfileScreenUI class which holds UI related to a user profile. There is also a ProfileScreenProvider class which is consumed by each of the ProfileScreens. A user can navigate to another user’s profile page over and over and do stuff which changes their state. UserA->UserC->UserB-> on it goes on. The screens are totally unique to the corresponding users. So each time the user navigates to a new user (or even the same user’s profile), I create another ProfileScreenUI class using a separate instance of ProfileScreenProvider class as a controller. Because that I give each of the new ProfileScreenUI classes a provider class, they always use the closest one up in the widget tree which is the new ProfileScreenProvider instance. Can I do this with GetX?

How do you manage with a RX for a model that has required parameters to make it .obs?

Great tutorial friend, I use Get.put() to get Getbuilder to properly work but it keeps the controller's data when I leave the screen, and I want reinitialize it, how do I go about it ?

Hello Again, Say I want to create a simple component with only one variable and it ought to be reactive, which shall be more expensive then statefulwidget or get ?

Thank you, How to make controller available for all route like BlocProvider in flutter_bloc, Like login controller i want it to be available in all route

can i use getx, obx, getbuilder in same extended class of GetxController class?

do you have more complex getx example or video and more complex form data with backend service api for end to end knowledge want to learn. Thanks in advanced.

How it can implement change state in UI depending on the for example status of downloading data from Internet ? I mean I want to show progressBar when data is downloading, how I can do it in Getx?

7:52 update a instance of a class, 12:16 update a variable, I have to use update method which is option 2 for update user (instance of User class), update a variable works well without using any update function

Very useful. Thank you

Hey I'm starting a new project and am at a crossroads of GetX or Provider/Riverpod. GetX is amazing, but it's new and not a ton of resources or support yet. Seems using GetX is a bit of a gamble since it hasn't "proven" itself quite yet and Provider is tried and true. I see some people say global state is not a good idea and question if GetX can scale. What are your thoughts? Are you going to use it or would you recommend it for a production app? Thanks!

It was nicely explained.Great tutorial:)

hello, do you have an example of how to use this with googlemaps? I need some help

tnx! really comprehensive tutorial.

I was looking at applying this to an app I am writing, and I was wondering how you would approach this use case: Using a Navrail, you have created a stack of containers representing pages/views. The user taps and the currentIndex is updated through a simple setState...the page changes. The ever present problem of reaching back to the navrail's currentIndex to change pages from within the page. I uses a ValueChanged to a call back... Which of the many forms of Get would be best?

Is it possible to change appBar title with obx or getx? It's like onClick title change?

Awesome tutorial mate! Thks

Hello there im someone who has been stuck with RxVMs approach of state management , and i have really liked how getx simplifies Reactive solutions. I have one question though, how do i combine multiple Controllers together so i can create a Centralized State in which i can access anything in it? Thanks

thank you so much, clear, concise and very well articulated! question: what's the getx equivalent initstate, superinit and setstate? been trying to get a basic camera screen setup but not sure where cameracontroller gets called, how to set which camera to use and how to dispose. would appreciate some help "translating" / refactoring from standard statedul widget to getxcontroller. most tutorials and examples (like camera package example) use stateful widgets and theres not enough info out there to help me wrap my head around to reverse engineer how getx is working. anything would help, i'm bashing my head on keyboard. perhaps it would be a useful quick video tutorial as well? thanks for your hard work!

Hello, Can I ask can u create a video on how to use Timer in GetX? I have a problem because it's counting but I can't update UI every second no matter what I'm trying thank you.

Well done!

123/5000 You think it is possible to put an MVC example with obx or getx for updates from a database values and update the view?

Thanks. Very useful. Looks like I want to move all my stateful widgets to getx. I am trying to find out how to use 'typical streams', like getUserLocation/Calculate distance to somewhere with getx.

if you click home and re-open app from stack, the app will restart ??

Seems good, maybe I should try to use this instead of bloc for my next project. Just a clarification, what if you have an observable on screen 1, and on screen 2 you have called a method that changes the value of observable in screen 1. Does the screen 1 obs will change the value? Anyways thanks!

uhm, 14:14 how can we increment the value even though it's final ? or is that because we're using e.g. `count1.value++` tysssm btw you're amazing

Yeah!

It's amazing. Amazing !!!

Why my code not recognize RaisedButton? :C Pd: im using visual studio code on macbook

how to use Getx for bottom navigation bar.. mean i want to change index of bottomnavigation.. i just want to do that i have 4 screen in bottom navigation bar and in first screen i have button ..on press i have go to second index of bottom navigation..

You're a blessing. Thanks!

How can I access one controller from another? This isthe critical point in any non-trivial App and would be the reason for me to switch to GetX from Provider as it is very painful there...

Awesome

It's so cool, I love it

Hey! Thanks so much for these videos. I am trying to apply this with the class model {} and data from mongodb to update users or getting messages or sending messages. Would be great to see these with GetX on here or even on Udemy or other tutorial sites.

Thank you.

Cual es la diferencia entre GetBuilder y Obx? Actualmente uso el Obx de esta manera. Obx( (){ if(getController.variable.value){ return SomeWidget(); }else{ return Container(); } )

Hi Tadas. Thanks for your amazing video. You mentioned that you were goning to use GetX for your next project, I am wondering how did you find it so far? I am going to use GetX in my project. your answer would help in my way! Thanks

Nice tutorial !!! I've been worked with it a long time ago ... but it this moment I'm trying to put tabs inside a view with N controllers 1 for each tab. But I've and error when I'm trying to call a method inside my apiRepository. "The method 'logout' was called on null" I took this tab out the tabs view so the method is working fine ... But I need a view with it's tabs. Did you try it ????

When do I use GetX and when do we use ObX? How can i decide?

awesome sir

Thank you

do you have any tutorial using ValueBuilder ?

I'm new to flutter, Will getx hold data even you move into different screens?

OOOOOOOOOHHHHHH THANKS VERY VERY MUCH.. i was wondering where do i trigger the change it was just to put controller.update();

thanks a lot!

There's a widget called 'Getview' in getx. If I called update in the controller, will all child widgets of 'GetView' be rebuilt?

MAn one question, can i create immutable classes as states?

sounds good

Hey thank u for the tutorial, I am trying getX on my project, I want to rebuild the whole widget tree of a page so I put empty setstate({ }) while using getx (so its working fine), I want to know is there any way to rebuild widget present natively in getx ?

what about initState, dispose if use only stateLessWidgets?

can you create a video using getX, pagination API?

differnce between get.put and get.find

The getter 'count' was called on null. Helpp

Where is MixinBuilder ??

You dont need 'Get.Find().increment();' just use the context '_.increment();'

If I want get user to figure out if he logged or not in or before GetMaterialApp for navigate him to login or home page how ?

Your voice is cute =)) and thanks for the tuts

zoom in the code for your next vid releases. :)

ithink iwill stick with getx because i get used to it

why does getx get a lot of hatred?

太棒了

Brrrrrrrroo canımı yeeeeee. Sen de az copy paste yapmıyosun ama olsun. Mikrofonunu sevsinler.

Can you tell me the cons of GetX?
