navigator | Navigator -

The minimal reproducible code below aims to have a loading icon when a button is pressed(to simulate loading when asynchronous computation happen).

For some reason, the Consumer Provider doesn't rebuild the widget when during the callback.

My view:

I'm developing a simple navigator with mapbox API for Android. I'm creating some routes using https://docs.mapbox.com/playground/directions/ playground and i would like to use the generated JSON to generate a DirectionsRoute object. So i call DirectionsRoute.fromJson() but when i do it, the application crashes with this error:

I am having trouble trying to iterate over a JSON array of objects from a remote URL using Flutter's FutureBuilder.

My goal is to:

• Fetch JSON data from an API
• Output the data into a 2 column gridview layout

The JSON data is an array of objects(or a List of Maps in dart), the objects have simple string data.

I know that I need to build a future to fetch the data from the API and decode the JSON, then I need to create a FutureBuilder to output the List data into my Gridview Builder. That is what I have tried to do in my code below.

Hello guys so I'm trying to make Splash Screen with Stack Navigator. So I Have 3 Main Files App.js , Home.js, and SplashScreenJs. I want my Splashscreen to move into Home after 5 seconds but I can't afford to make it. I was able to use console log with the UseEffect but not with the navigate. It shows error " ReferenceError: Can't find variable: navigation"

App.js Code:

I'm trying to use react-native navigation. I installed the app, everything went alright. Now I'm having this problem with Expo when I try and create a navigation in both ios and web:

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of ExpoRoot.

I am using IntelliJ and I use H2 database file (.mv.db) and I need to only view its contents whenever I add something in it. I thought I'd be able to file 'Database' tab in IntelliJ but I didn't find it.

This is what I want (image below)

When I click "View --> tool Windows" I don't see a database option (image below)

I am using Maven, is it possible that a certain plugin I downloaded somehow blocked/removed the database option?

I know there's 'Database Navigator' that I can download as a plugin, but its support for JDBC including H2 is experimental. So it's not a good choice for me. I can't seem to find the database plugin, is there any way to obtain it?

I want to use navigation bottom menu with using navHostFragment in main activity. But when I run the program ,it stops on setContent in onCreat method MainActivity java code. I try to use bindig class insted setContent directly but nothing changes.

this is MainActivity.java

I am creating an app where I have complete manual control over every back button press.

I basically have widgets/views changing in my app instead of the Navigator pushing and popping new screens.

I created a function where I am able to display views 1,2 and 3. and go back using the back button on android. however in case of iOS the back gesture does not work and I am unable to change views.

any workaround? Help would be appreciated

I have a navigation menu that I made for a test application, there are some tabs that I want to hide if I am not logged into the application. After logging in, these tabs should appear. The problem is that after logging in, I go to the desired page and I don't see all the navigation menu icons. For them to appear, I need to click on one of the available icons (only 2 icons are available for authorization) and only then the navigation menu will be updated and everything will be as it should be. All 6 icons will be visible! Can someone help me with this? Here I described the problem with the code that I am using. I would be grateful for any help.
