elevation copyright (c) 2010, dave shea all rights reserved. elevation is a route visualizer that renders gps data in 3d space. you'll need to have a gps-equipped phone or device capable of tracking your activity as you run, hike, cycle, skate, ski, snowboard, or whatever other physical activity you choose to map. you'll also need the ability to export that data as xml, in either gpx, tcx or kml format. (if you have files in just about any another format, you can probably use gpsbabel [to convert them to gpx files and get them working with elevation.). open ./data/xml/ -- there you'll see some example data

QUESTION
For a project for my study I am working on a React Native project, but I am stuck. I want to give the prop 'Score' to Card.js and based on that score a color has to be defined; 'transparancyColor'. Currently, the props are passed from Home.js to Card.js and the transparencyColor is defined there. Is this a smart way, or do I have to do this at Home.js? And how?
The code of Card.js looks as follows:
...ANSWER
Answered 2021-Jun-15 at 09:10Regarding the code structure question, it's fine, especially initially, to pass props down one or two levels.
In terms of code, something like that (note the convention is to start variable names with lowercase):

This is the code for the TextField. I've initialized it and I want this value to get print when a button is pressed if the text field is not changed.
...ANSWER
Answered 2021-Jun-14 at 14:35You have to declare your TextEditingController outside the build method and declare it as a field of the State Class. then when pass it to your TextField as the controller. then you can read the current value of the TextField using that controller as follows.
QUESTION
I am using one of materialUI's built-in components to display data on one of my sites. Currently, the code that was implemented is very closely based off of the examples on the MaterialUI API site. With that said, I have made a few adjustments for my own personal use case. This is how each of the columns that I need are labeled (5 total). I've also included my code below.
...ANSWER
Answered 2021-Jun-14 at 18:16You have the right idea about passing props to your CustomTable component to be able to change the data that gets rendered. Then, the parent component can pass the rows through the CustomTable component's props.
Here's a simplified example
QUESTION
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.
...ANSWER
Answered 2021-Jun-14 at 13:53Your page is not re built after logging in the user, that is why your nav bar is not updated. When you click on the button it refreshes and correctly displays the new elements.
Instead of using a global variable you could look into a state management package in order to make the logged-in user available throughout your app. (article for getx the simplest one out there)
If this is simply a prototype and you want some quick and dirty, I guess you could trigger a reload of your app once a user logs in by wrapping your app with a widget that exposes a rebuild method. (article)
EDIT: Example with Getx:
QUESTION
i have an error that i just dont find a solution for. I created a little messenger thingy in flutter and have a problem when using a NetworkImage inside one of my chat bubbles.
When i send the image as message, it is displayed without problem in the bubble. Also when i send multiple images, it is no problem and they extend beyond the screen and i can just scroll up and down without any problems.
Though when i reopen the room screen and there are multiple images and they extend over the visible screen i get _CastError (type 'Null' is not a subtype of type 'List' in type cast) from network_image dart file. BUT this only happens after a hot restart. If i just navigate back and then reopen the room screen its also all fine, but as soon as i hot restarted once i always get the error when trying to open a room, which has images extending the visible space.
Iam still kinda new to flutter, so i know my code sucks mostly but this time i just dont even find a "dirty" way to solve it.
Flutter 2.2.0 (beta channel)
Dart 2.13.0

Edit 1: i removed a lot to make it easier to read.
Edit 2: i found it to be somehow connected to using the downloadURL from Firebase Storage. When i replace the url with just some test png url it doesnt seem to be a problem.
...ANSWER
Answered 2021-Jun-14 at 11:07Ok, i kind of found the problem. I took the Firebase servertimestamp as variable for the filename in the Firebase Storage. That of course only resulted in the filename being
FieldValue(Instance of 'MethodChannelFieldValue')
Though i dont really understand why that was a problem, but now with a normal Datetime toString timestamp it all works perfectly fine. Maybe its some special character escaping in the generated downloadURL from Firebase Storage with this kind of filename.

QUESTION
Is it possible to retrieve DEM elevation values for use in a Mapbox Style expression?
Case in point - I'm using a custom DEM for terrain in Mapbox GL-JS. I would like to set the exaggeration based on the elevation value (lower terrain, higher exaggeration) via an interpolate expression.
...ANSWER
Answered 2021-Jun-14 at 10:27I don't think there is any mechanism to retrieve the height of terrain within an expression, so no.
In any case, according to the documentation the terrain type only has basic functionality (ie, not data-driven expressions), so you can't do what you're trying to do for that reason, too.

For better optimization, I decided to use the RecycleView in one part of my program to hold a set of DownloadItem instances. The problem is that the class takes two arguments: path & url_type which I do not know how to pass to the data of the recylceview. As a result I get the error below:

Answered 2021-Jun-14 at 01:06In order to use DownloadItem in your kv, it must have an __init__() with no required arguments. Here is a version that uses properties instead of required arguments:
