#23 || Flutter GetX Tutorial || Fetch API Data with GetConnect & StateMixin in GetX 

Hey Thanks buddy.

Also in user models .dart There is a msg says List is deprecated and shouldnt use. How to fix this

Resolved it

It's not omer it's Amar

Ok

In the view you can use onLoading parameter to use your custom loading indicator

Can you please provide a link i also trying to add loading idicator but cant I make true is loading in provider and try to add it to the home view class under body.obx and also above return card but not working

Please refer my todo app videos in GetX playlist

I have not used the model in the example...just discussed how to create that...but if you want to use you can

@@ripplescode Sir Thank You for reply. Now i understand.

Ok

@@zaidbashir2001 At the model dart file generated, you must manually change the "Class ?" into "Info ?" or "Name ?" or "Dob ?" according to the classes name created by get_cli 1.6.0 (see the below part of the model dart file). Somehow the get generate model can create the correct Info class, Name class, Dob class etc but can not MAP them correctly into their class definition name at the top part of the model dart file (it just simply write it as "Class ?" which mean we must look at the correct corresponding "class name" in the bottom part of the model dart file). Example: Change "manually by yourselves" the: Class? info Class? login; Class? dob; Class? registered; into Info? info Login? login; Dob? dob; Dob? registered; then it will work. Notice that the dob and registered json sample file have exactly the same data structure so the get_cli only make 1 new class called "Dob class" so you have to use Dob for "dob" variable and also for "registered" variable (the get_cli is smart enough not making new "Registered class" as it detect it have the same data structure as the "Dob class" it already made inside the model dart file). Also, add "!" (the null check) in some part of the model dart file created by get_cli (as get_cli somehow maybe not fully comply yet with the "null safety" feature of the new flutter version. Example: at: results.add(Results.fromJson(v)); change it into results!.add(Results.fromJson(v)); After doing the two things above then the model dart file will no longer produce errors.

In GetX provider we write the code to get the data from server...from controller we call the function declared in provider and use that data in our UI.

Go through entire playlist...I have used List as well.

nvm. i fixed it

Yes.. there is some problem

@@ripplescode can we generate freezed model class with getx cli

Never tried...will give a try.

@@ripplescode thanks

Check description

@@ripplescode thanks you 👍

body: controller.obx( (state)=>Text(state.yourField), onLoading: CustomLoadingIndicator(), onEmpty: Text('No data found'), onError: (error)=>Text(error), ), );

Do you also face problems when creating a model dart file using the "get generate model with..." from the command line? (that is the model dart file created is showing error here and there, this is using get_cli 1.6.0 and flutter 2.5.1)

I think you are getting errors because of null safety...

Whatever you want

Thanks for liking the video....but I didn't get your question completely. Please refer Todo app in GetX play list...I hope you will get the answer.

@@ripplescode Thank you for replaying me. This is my view Architecture - Scaffold |__body |__Column |__[ List of Categories Button ] |__[ List of Products ] N.B: parent widget controller.obx() Functionality - # At the beginning it will show some random products in the [List of products] view section. # When clicking a category buttoon from the list of categories button, it must show that related protects in [List of products] view section. It is easy without using StateMixin but iI want to do it with StateMixin because I think It follows DRY [Do not repeat yourself]. But the problem is when I click the "Categories Button" it does not reflect the UI. But in the backend, it actually fetches the data from the database. I am really sorry for the long explanation hopefully it makes sense to you. If it's not clear to you, could I have your email for more explanation if you want to. Really Getx makes my life so easy. Thank you again.

Can you share the dummy code to ripplescode@gmail.com...instead of database just load the data from local JSON file and send it to me....in my spare time, I will surely check.

@@ripplescode Thank you so much. I already send an email to you.

I received your mail....I will definitely give a look at your project in my spare time.

For your kind information I have not deleted any comments of yours.

@@ripplescode I have written like 3 comments before and it is gone... Well, I am sorry if maybe there is some misunderstanding between us. I just try to help the community here to find a fix for the tutorial that might not work with the newer flutter version. 1 thing I want to ask is, did you have to edit manually the model dart file generated by the get generate model when making this tutorial video? or not? It seems the new get_cli and new flutter version if used with the same json data file will not produce the same result as in your video Sir (it will need some "manual editing" again so the model dart file result does not generate errors, and it is not just because of the null safety, it is because the get_cli get generate model can not map correctly the "class name")
