Mediaquery | Titanium Android module to use with MediaDroid app

I am having trouble trying to iterate over a JSON array of objects from a remote URL using Flutter's FutureBuilder.

My goal is to:

• Fetch JSON data from an API
• Output the data into a 2 column gridview layout

The JSON data is an array of objects(or a List of Maps in dart), the objects have simple string data.

I know that I need to build a future to fetch the data from the API and decode the JSON, then I need to create a FutureBuilder to output the List data into my Gridview Builder. That is what I have tried to do in my code below.

I have a navigation menu that I made for a test application, there are some tabs that I want to hide if I am not logged into the application. After logging in, these tabs should appear. The problem is that after logging in, I go to the desired page and I don't see all the navigation menu icons. For them to appear, I need to click on one of the available icons (only 2 icons are available for authorization) and only then the navigation menu will be updated and everything will be as it should be. All 6 icons will be visible! Can someone help me with this? Here I described the problem with the code that I am using. I would be grateful for any help.

I made a website with PageController to control the scroll of some screens. And I made a menu section with screen names, and when any of them are pressed, the user will navigate to the respective screen.

The app is working fine. But I refactored the menu button so I can control it's style, and to add animation in the future.

But when I refactored the button, I can't pass the PageController index, or the nextPage function.

That's why I thought of using the provider package. However, I didn't the package before, and my setup seems complex. For I should pass the PageController state to the button, and the button should send the nextPage function with a new number.

How can I achieve this?

Here's my code:

The button:

════════ Exception caught by rendering library ═════════════════════════════════ A RenderFlex overflowed by 103 pixels on the bottom. The relevant error-causing widget was Column lib\…\words\add.dart:61

what should I change in my code? Is there any way to do it? In case you want to see the code please let me know I will update more

I am currently trying to get the current user state from FirebaseAuth and switch between home screen if user didn't logged out or splash screen if user is logged out. User registration and login are both successful and registered in firestore database. But everytime i closes the application from my phone and re opens, the MediaQuery.of(context) width has a null value and shows an error.

But the bottom navigation bar is still showing. It works when i rebuild the app and login again, it brings me to the home screen. It only occurs when i close and re open the app.

I created a custom button where it expands on the first tap, and on the second tap, it will go to another screen. Now, the problem is, I created three instances of that button. So, the button that I tapped first remains expanded and would not go to its initial size. I would like to make the button return to its initial state whenever the user taps any other widget. Sorry for my code. I'm still practicing. Hope someone help.

Here is the code for the custom button.
