I am trying to pass on the text selection of the user as a string to convert it to the document path of my Firestore collection.

Unfortunately, I get the error message:

Variable 'enteredText' must be initialized in line

I am trying to build two an autotextView that should be passed on to firebase to look for the according documentId there to show 3 values of that document.

My problem is that I cannot connect the documentId of the first part (autoTextView) to the second part (firebase query). The two individual parts work fine, but the connection between the two trough the documentId string doesnt seem to work.

My problem is that I dont know how I can call the document name (saved as "enteredText")

in line

I am trying to build an autoTextView with a firestore connection.

I already built a working autoTextView application in which the data is saved directly in the strings.xml file. I also already connected firestore to my app.

What I am trying to do now is to replace this data frommy strings.xml file with a connection to firebase. So the user types something in in the autoTextView, the auto completion options should come from firebase and not from the strings.xml file.

Does anyone have an idea how I could try implementing that?

i am stuck in the problem that, i want to visit my ViewModel in a RecyclerView´s Adapter, but i have the Exception: "Your activity is not yet attached to the Application instance. You can't request ViewModel before onCreate call"

I have a MaterialApp in my main.dart within a Nav() Widget which contains a Scaffold with an appBar and a BottomNavigationBar. The NavigationBar has 4 BottomNavigationBarItems, but I have more Pages than 4 in my whole App. The other pages can be accessed via the first BottomNavigationBarItem 'Home'. But when I push the new NamedRoute the AppBar disapears. How can I solve this Problem?

I've already tried using the bottomNavigationBar in my own Widget in a new File. Problem: setState() doesn't work.

Here's some code

main.dart:

I'm now googling for quite a while and I just don't find any solution to my problem.

I am using argparse to parse some command line arguments. I want to be able to parse an arbitrary number of arguments > 1 (therefore nargs="+") and I want to know afterwards how many arguments I have parsed. The arguments are all strings. But I get a problem when I just have one argument, because then the length of the list is the number of characters of the word and not 1 as in 1 argument. And I want to know how many arguments were parsed. Does anyone know how I could solve this problem?

examples:

I'm currently trying to build a word carousel in Angular. The idea is to have an array with x elements that are changing every 3 seconds with a fade so that it don't looks hard. The problem is that I've just managed to show the fade animation on the initial page load but not on every word change.

This is my animation:

I want to fetch and join multiple collections based on user's location with geofirex:

I am trying to run the bergman package http://servus.math.su.se/bergman/manual/manual.html#htoc3 in either Lispstick or Portacle. I downloaded both of these programs and installed quicklisp in them. I also already downloaded the "current version packed for Windows". However, the manual of Bergman doesn't really explain how to run it here, it just says

"You can start a bergman session by typing bergman followed by Enter."

(So, for example, I don't even know where I should be typing "bergman"...)

Could someone quickly explain how to do this? (I am using Windows 10)

Disclaimer: I am a mathematician trying to do some computations with the bergman package for LISP, so apologies in advanced for my absolute lack of knowledge on all of this.
