goback | Golang simple exponential backoff package

I have a screen that displays a Flatlist with some data in it, but when I go back to the previous screen and come back back to this acreen with the Flatlist, the data is not more there. I use React Navigation to move between screens and also to move data.

This is the code I use to go back:

I'm building a RN app and I just recently learned REDUX and applied it into my app. I have a shopping cart feature in my mobile app. On one screen the user can add items to the cart. Then when they are done they can click the cart icon to view the full cart (new screen).

Shown below is the code for my cart screen.

I've found a very useful Jquery example to filter divs based on changing select options.

Here is the fiddle: https://jsfiddle.net/vgdwyqxb/

My problem is: I use this code for filtering projects and every single project has a URL that goes to another page. When a user clicks on a project, he/she goes to project detail page. On those pages, there is a "Go Back" button. When they go back, all filtering selections are lost. I want to hold the filter selections.

I added a goBack() method in other page to go back to filter page. When I click on goback, filter page remembers which option was selected but all divs appear (not filtering divs). As far as i know "changing option" must be done in order to filter divs, so when i go back to filter page, even my last selected option is selected, it doesn't filter anymore.

My question is: What should i do to make filter page remember when users go back from project detail page?

Thanks in advance.

i have the following code in react native ,

I have been making an Atari Breakout inspired game based off of a tutorial. I was wondering how to make a "GAME OVER" screen that will show up once the player dies. The code that I have has a variable that I created called "DrawDeath()". I have it coded so that text appears when you die but for some reason it never shows up.

I want to detect value is changed when hardware back button pressed.

but, using BackHandler in useEffect, it is not working.

here is my code...

The image in the header constantly flickers when I type. May I ask how do I stop this flickering at the top right hand corner or accessoryRight? I am using this TopNavigation component from UI Kitten UI library. I don't think this is normal, it shouldn't happen at all. I must be doing something wrongly.

The flickering happens in the title and the right side of the Navigation Header.

I made a separate component for the TopNavigation and then call it in respective screens.

Things I have tried:

• Since the outcome of the Header relies on navigation props, I tried using useState and useEffect (with navProps as the dependency) to save the prop instead of reading directly from props, but to no avail
• Directly adding the jsx into the TopNavigation's accessoryLeft/Right and title options

Any input is welcome, appreciate it!

The WebView Code

this is my front end code, I think the problem is here. So, when the form is submitted everything that is supposed to work works but the email shows up empty. Also I was getting an error in the console here it is...

Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.

So, i added that useEffect clean up function although im not sure if i did it right the error is gone. Are these two things related? Somehow the state is not being updated in time. If i hard code the message the email sends out fine. Thank you. Also any additional advice would be cool.
