navstat | An effective navigation station for marine applications | Navigation library

I have developed a website using react and now I've been trying to use this via webview in react native.

Problem: When I am using back button, the app exits.

Reason:

• In my React Website I am using Link {from react-router dom} so the navigation is not being added in history.
• In React Native since onNavigationStateChange uses history, navState.canGoBack() is returning false.

What can I include in this else block in handleBackButton so that app doesn't exit?

Good day everyone,

I have a problem with an App that gives me some headaches for couple days. The App consists of a WebView containing a PHP WebShop and a bar-code scanner. So far everything was working as expected.

For better Navigation on Android I wanted to use the HardwareBackButton to go back in the WebView History. This also works well but has a major flaw. I want the back button to go back until it cant go back anymore and instead it should exit the App. Now to the actual problem: the last Page url is 'about:blank' and results in a blank screen. From here the canGoBack state is false and the App exits as expected but if you open the App again its still in the 'about:blank' state. My first workaround was to add this.WEBVIEW_REF.current.goForward(); before BackHandler.exitApp;. This helps to get the App back in a navigateable state after exiting but i would like to completely get rid of the blank screen.

I Hope the code below is enough to understand what i wanted to achive:

I've been struggling for hours to center my nav bar.

Here it is :

As you can see, the nav elements are slightly to the left, and not centered to the body. (the body is perfectly centered).

Here's my code :

I am rendering another component in a form because it needs to change on a selected option. I am console logging all of the info needed in AuxiliaryForm and it's showing up as expected. No errors are occurring. It's just not rendering.

This is the main CreatePage

In my effect I am dispatching two actions: one to load the participant, another to update what should currently be on the "nav stack" --The latter is because we are planning on implementing a system where by depending on what component a user selected, we need to keep track of what was before so that they can navigate back to it. The issue is that in the component it properly catches the change in the value of the participant, however, it does not do the same for when the navStack state is updated.

Effect:

I have a react native app which loads in a url in web view after login. The user moves in the web view clicking links as supported. Now I want to open share options from inside the web view by clicking on a button in the web view. When we click on the button, we have a url but I am unable to detect that url with 'onNavigationStateChange'. So how can we handle this without the url? I have tried many links, but none gets me the result. The 'OPEN SHARE CONTROLLER' is never reached, neither does 'navigation type click'. Here is my sample code:

I have 6 buttons and when I click them the style is changing. However, it doesn't work regularly. I think it is due to my state controller but I couldn't solve the problem. I'm gonna describe it one by one now.

Ok... I'll preface by saying i am a bit of a noob. I am building a BASIC react-native app using expo. I say basic, in that I am building the app to simply be a webview of the mobile version of our website, to keep everything in one environment (all our databases, etc.) and being able to make changes to one place, etc.

That said, I am still attempting to create Touchable Opacity buttons that will allow for navigation to specific URL's of our website within our existing webview. The problem i am running into with my current code in App.js is that i cannot find the right function to make webview render the desired "page" onPress. (See code below)... For example: If I press "Home" button, even if i have navigated to a different URL within webview by interacting with the webview, because my current "state" is still considered to be "Home" within my current process, nothing happens. However, onPress works, with the code i am using below ONLY in the event that you are not currently within that state. I am kind of stuck, and not sure how to make this happen so that when pressing "Home" or "Media" it will re-setPage, effectively re-rendering that page.

I am opening a url in webview. On opening the webview (let say page A), when i traverse or go inside any other options by clicking some options, some other page gets opened (let say page B). Now when i click on the hardware back option, i want to return to the previous screens that is (page A). And again n clicking back, i want to return into my app.
