I have a simple drawer in Flutter project and I want to make the drawer to be always above bottom navigation bar when ever the user slide/open. I play around with my code but can't find any solution yet.

i have the below code that I am receiving from API a list with posts , when I open the application the list if I saved to code again the list display correctly , but every time that i restart the app the list is empty, any ideas? I am new in flutter so if I have something stupid please forgive me

I am using VS and I am running the app via VS debugger, also I dont get any error, maybe the list is not available?

I'm using Flutter for first time for one of my projects which is a Newspaper App.

The problem takes place when I try to navigate from main.dart to newsfeed_for_other_category.dart using MaterialPageRoute from my Drawer. In that screen it shows the news but with a black background. But in the screen newsfeed_screen.dart which is called in the body in my main.dart it shows perfectly.

I'm posting the codes below.

main.dart

The following code is almost a copy-paste from the official flutter github example for the bottom navigation bar. The problem is, at the opening of the widget containing the views, everything is preloaded. And each time I press a bottom bar element I have all of the views reloaded. In other word when I press on the first item, the log shows me that the other ones(second and third) are making network calls. When I press the second, the log shows me that even the first one is making network calls. When I debug I figured out that at each time I select a widget from the bottom bar the widget that contains it rebuilds(there is a call to the method buid). Is it a normal behavior? this is the code of the containing widget

I have seen the various methods of changing the state of a parent by passing down the function and updating it in the child. I have passed the function down successfully, however, the state of the parent does not change on my onClick event. The Parent component does rerender as I am able to see in console.log. Also, I am using a functional component as the child, however, I did try changing it to a class based component with no luck (don't wanna lose my hooks). Here is the parent component:

I am new in flutter. And I try to demo app. I need a IconButton on appBar and I create it. But I set padding to IconButon and icon position changed but click wave effect not changed with iconButton.

I want to correctly set padding to IconButton.

Here is my appBar :

I want to let a element to do "fadeInDown" and "fadeOut" animations

I click a button and use v-show to determine whether let it show up

The issue is that this animation work well at first time,

but at the second time the element will fadeInDown for a while and then automatically disappear(probably fadeOut)

here is my html:

I am trying to write a small to-do list project using materialize css library. In my project, I have a button which triggers a modal containing a form with two picker elements - date and time. The first time I pick either the date or time, everything works, but if I try to edit my initial choice - the browser freezes. I use the latest version of Firefox. Also, I pass option parameter container to both pickers to make sure they render using all available space instead of only using the space provided by the modal which calls them. I hope this makes sense. What did I do wrong? How to ensure my browser doesn't freeze executing the code below.

I have a icon modal component which display material google icon The idea is to send back the clicked icon (letter) from Modal.js to app.js by a callback function someFn which will change state of letter but I get Uncaught TypeError: Cannot read property 'someFn' of undefined everytime I click on an icon. I don't understand what I'm doing wrong
