I'm trying to create a web app that only renders one page, and the other pages (or views) are rendered when you press a button related to that specific view. Like the Flutter Gallery website, when you click on a widget info in the "Categories" section
Is there any workaround for this or do I have to create my own router?
you can keep all widgets on one page package by creating a switch statement in your build page. switch between different widget when rendering the scaffolding.

I'm developing an app in Flutter, and I'm stuck with this: I have a list of widgets that I generate dynamically. When I press a button, I need to show or hide one of the widgets in the list. I use the Visible widget to show or hide them.
The problem is that I need to know how to update any of the specific widgets in my widget list as they are dynamic and are separated, it is getting complicated doing int programmatically.
How can I do it?
PS: I have the same app developed in Android Studio and I do it by traversing for example the child Views of a LinearLayout and then I ask for its id programmatically.
I designed three onboarding pages in figma which contains information about my app, while wireframing the app, I added smart animate to the three pagesThis is the first onboarding page
The second one
The third one
The smart animate enables smooth transition from each page to each page
While using flutter, I created 3 different pages for each onboarding pages and added a navigation widget to each button
But the navigation from each page to each page was stacked
I also tried using gesturedetection() onhorizontalswipe still same result
The pages navigate in a stacked way totally different from figma's smart animate option.
Is there anyway I can do this?
I'll appreciate any help
Thanks in advance.
From what I understood,
You want to build an onboarding screen with some animation. But the pages are being stacked.
It is happening because you are navigating to different pages with each button press. That is very bad practice for building an onboarding screen.
You should be using a PageView widget that allows you to transit between pages without navigating to them.
If you want to use a plugin that suits you, I would recommend introduction_screen
I need all the functionalities (e.g., Searching) that a WebView provides on a WebPage but don't want to show any WebPage (provided to the initialUrl property) in the UI.
Instead, I need to show Custom Widgets inside the WebView widget upon which I can perform operations similar to Web Pages.
So, my queries are:
Is it possible to achieve this using the WebView widget?
If not, is there any Widget available similar to the WebView widget that can fulfill my requirements?
I'm building multiple form pages in one class, I create 4 widgets each widgets is represent a page with text fields or cards or radio buttons.
and I create a method to switch between pages when. I press next.
This works as expected ^^
My issue UI inside first page is not refreshed unless I press ctrl + S,,
inside the first page of the form, I have created custom radio buttons they're simply cards.
and when tap on any card, there's set state method, to highlight the selected card by changing its style..
This works perfectly! at the beginning when I call the first page 1 directly as a child inside the scaffold..
However, after I created the method to switch between pages.. The UI in page 1 does not refresh..
I will put a picture..
Picture of the method to switch pages
Picture of pages widgets
picture of scaffold and how I call the widget pages
this is a picture of custom radio button which has cards, the card color change if it's selected
I tried many ways! but it didn't work..
Is what I'm trying to do correct? I'm a beginner in flutter
& I have a project to submit :(
I couldn't find a solution in google,,
Try making the widgets StatefulWidget and call setState((){}) inside the widget when you tap on the cards.
So here's what I did ^^
because the issue was just in page 1, so I in the scaffold I added page 1 as it's child directly without Switch page method..
Then inside page1, a button that will navigate to another class,
the second class has exactly the same scaffold and app bar as previous page.. But, in it's child I added calledWidget which switch between pages from 2 to 4 in my case ^^
So short words, I put page 1 in a separate page and the rest of the pages in a switch method in separate class
it works, but I hope I don't find any difficulties When saving values & integrating API to post the values
what you think?
I'm making an app with a BottomNavigationBar with 5 different screens, each of them has a web view. The problem is that everytime I come back to a screen that was previously loaded, it reloads. I have tried using AutomaticKeepAliveClient from copy pasting this code but I doesn't seem to work. I'm new with Flutter so be precise please, thank you.
AutomaticKeepAliveClient is mainly used for keeping a child alive in lazily rendered list views. In your case whenever you switch tabs your current page get disposed and new page materializes on top of it, that means each time when you switch tab a new page is created including all it's widgets.
So if you want to keep your previously loaded web views alive, you have to go with either PageView widget or use Stack widget to load your pages programmatically while the user clicks on a tab.
This is a detailed example about implementing your requirement using PageView widget . you can also find an example with Stack widget under that question.
