linux build: black screen

[throwException]

Bug Description

The screen went black as soon as the initial dialogs (connect, cross signing) were done.

Also, the following exception appeared in console as soon as I pressed any key:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Null check operator used on a null value

When run using flutter run, 1.20.0 shows a black screen on start, but shows chats on the first keypress.

I have the same problem on NixOS. Screen remains black. I do not get any error messages in the console, though. I've searched the Flutter repository for similar errors, but looks like no one else has this problem.

That bug came with the new flutter version. However you can just use the stable channel (which you should use anyway)

I had to go back to flutter 3.19.6 to build a working version of fluffy 1.20.0.

I suspect I just ran into the same bug after updating NixOS to 24.05 - an additional observation if it is helpful: the contents reappeared if I opened a chat or hovered over the button in the top left corner. Here's a short recording of the settings screen showing off the behavior I observed.

Same deal here. Also using NixOS 24.05 & Plasma 6.

I'm seeing the same thing on ArchLinux, Fluffychat-localflutter 1.21 with Flutter 3.22.2. Blindly selecting a chat in the sidebar fixes it, but only until the next restart.
