bubble | : speech_balloon : A simple and lightweight C11 dialog | Speech library

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 On Android Emulator Pixel 4a API 30

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.

In my AppBar the color of my StatusBarIcons is white, just because auf "Brightness.dark" If i use that in my SearchDelegate Window the the body color is dark too. If i just change the primaryColor to grey, then the StatusBarIcons are still black. Has anyone an idea to solve one of these cases?

PLUS: how to change the blue icon/bubble below the cursor and the two underlines white and green, picture 4?

I have an array which stores highscores to a quiz. I have a for loop that should get the bubble sort to go through all entries, however it doesn't function as intended and seems to

All the scores before the sort appear like this:

[(3, ), (0, ), (1, ), (0, ), (3, ), (0, ), (0, ), (3, ), (69, )]

And after the sort is 'completed', they appear as:

[(3, ), (1, ), (0, ), (3, ), (0, ), (0, ), (3, ), (0, ), (69, )]

As you can see, they appear to have sorted to an extent but it doesn't fully loop back to the start and resort until they are fully in ascending to descending order.

The code for this is:

A permutation of integers from 1 to n is a sequence a1, a2, ..., an, such that each integer from 1 to n is appeared in the sequence exactly once.

Two integers in а permutation form an inversion, when the bigger one is before the smaller one.

As an example, in the permutation 4 2 7 1 5 6 3, there are 10 inversions in total. They are the following pairs: 4–2, 4–1, 4–3, 2–1, 7–1, 7–5, 7–6, 7–3, 5–3, 6–3.

Input n and array[n] 2<=n<=100,000

First I solved problem with bubble sorting but then i met time complexity problem.

Second I solved it mergesort but I didn't do well

Here is my cord

have the following code to compare the time of bubblesort and quicksort:

I'm building my first Android app, so apologies in advance for my lack of expertise. I've been banging away at this issue for 2 days so far. When I set the sound to mute in my Settings Activity via Shared Preferences, the setting does not 'stick'. Here is the code from my Main Activity:

I'm making a bubble map similar to this one: https://observablehq.com/@d3/bubble-map

Everything is working except that my smaller bubbles are not always showing on top of the larger ones. I can't see why, as I've sorted the data before drawing the circles. Can anyone see what I'm doing wrong?

Here is a plunker: https://plnkr.co/edit/JKWeQKkhN2TQwvNZ?open=lib%2Fscript.js

Code is below. The other files are too large for stack overflow but can be accessed via the Plunker.

When I adjust my config for Particles.js, the background color/image do not change from how it comes. I am not sure what I have done wrong. Here is my code:
