I created an application in flutter where I put Raisedbutton's everywhere. I want to change them all in Neumorphicbutton. Is there a way to change all Raisedbutton's into NeummorphicButton without editing one by one?
Thank you.
You can use refactor tool to change all occurrence of Raisedbutton to Neumorphicbutton. If u want to change all of them at once
Assuming that you want all the buttons to change into a neumorphic button style by clicking a single button , you can use the Onpressed() function and have it call SetState , in which you can change each and every button to Neumorphic style

i have a page named displayData . On it there is a button if i click on it it shows DraggableScrollableSheet normally it has a button done when i click on it the icon of the page on the bakground (DisplayData) must change .i used a variable in a setState but it doesn't work it's true on the DraggableScrollableSheet but always false in display data
any help !
for this type of cases, there are several solutions, I recommend the use of providers, in this way with the use of 'extends ChangeNotifier' you will be able to detect the changes made without having to use the setState and you will be able to call from any class (or page ) the variables you need
you can use callback methods from on widget to another, if you have much complicated scenario then I suggest using state management libraries like Provider, RiverPod or Bloc.

I want to show my own page on dropdown button tap, then item selected on page should be set as dropdown button value.
So basically, I need DropdownButton without any popup on tap. When I use onTap still default popup will be shown, how to prevent that?
why you don't use a button instead? or you can try to create an Inkwell put a container on its child and make it look like a button and write your code inside Inkwell OnTap(){}
1- Pass null to items parameter to disable the button.
2- You'll notice icon's color will be grey with disabled button, you can change it by setting color of the icon you send to icon parameter or send color directly to iconDisabledColor parameter.
3- You'll not use value parameter, instead you'll just use hint to show both your hint and your value. and update it using your state management after you pick new value from your own page.
4- Wrap your DropdownButton with GestureDetector or InkWell to show your own page when you tap on the button.
5- If you want to customize your DropdownButton shape, size and more. You can try my new package DropdownButton2. It's simple, easy, based on Flutter's core DropdownButton and have lots of features.
I was able to override the back button onPressed behavior using WillPopScope. Now, whenever I press the device back button or the default AppBar back button, the code inside onWillPop runs as expected.
The problem now is that I want to have my own custom buttons to navigate backward, but Navigator.of(context).pop() doesn't check the WillPopScope as if it doesn't exist.
Is there a way to simulate the system's back behavior or call it somehow?
I know I can just call the same function that is called by
onWillPop() manually upon pressing my custom back button, but I was eager to find a cleaner method, as in the future I could easily forget doing that and cause bugs.
In simple cases, when you need to intercept the Android back-button, you usually add WillPopScope to your widget tree. However, when developing stateful widgets that interact with the back button, it's more convenient to use the BackButtonInterceptor.

While using StateFullWidget, It is more convenient to use BackButtonInterceptor.
Hope this will Helpful.

The key was to use Navigator.of(context).maybePop()instead. Or more specifically in my case, was to use Navigator.of(context, rootNavigator:true).maybePop() as I was using nested Navigation.
I want to know, when we should should use streamBuilder and when we should use setState method. Should we use only one way in the project for one code style or we can use are both ways.
For example, we have radio buttons. We can handle it and to redraw after changing radio button via streamBuilder and via setState, but what way is more useful?
Is there any way to achieve this behavior?
Currently when I use the addPostFrameacallback to force the state to show the indicator, it launch the onRefresh function.
To show the RefreshIndicator manually, just attach the RefreshIndicator() to a GlobalKey<RefreshIndicatorState> by adding the previously created GlobalKey<RefreshIndicatorState> to the key: property of the RefreshIndicator(), and trigger it anytime by running _refreshKey.currentState.show();.
If you want to use the indicator as a loading icon, can't you instead use CircularProgressIndicator and animate it to act the same way?
