I'm experiencing the same issue on Arch Linux (binaries from the site) using Wayland (not sure if it's relevant though).

Erin · Answer 2 · Sun Mar 07 2021 02:10:16 GMT+0800 (China Standard Time)

Same with ubuntu 18.04 LTS with x11 - it looks like it tries to open a json file that doesn't exist and just crashes.

Maybe a solution would be to check if exists and if not load defaults/create file before launch?

Okay I spent a minute trying to debug and here's some info:

Missing Local File:

There should be a json at ~/.local/share/flutterfolio/app-model to load
Creating a json file (example below) solves this error but a new one appears

app-model example file

{
  "currentUser":null,
  "winX": 0.0,
  "winY": 0.0,
  "winWidth": 600.0,
  "winHeight": 600.0,
  "enableTouchMode": false
}

Actual Issue

Summary

~~Bitsdojo Window package does not support linux yet, throws a unimplemented error and causes the app to fail.~~

~~Note in the package repo before getting started they say that linux support is a future goal, not currently working~~
It calls out linux_title_bar.dart as the project error source during the build

Edit: I see that gskinnerTeam has forked the bitsdojo window package and created a linux platform variant and comparing against the windows platform code, it looks like it -should- work (assuming that the windows platform code works). The appWindow that extends DesktopWindow overrides the proper method (returning null), and is a deadringer for the windows file with the name replaced with linux.

I have no clue, maybe it was built with the wrong version in cache or pulled a later bitsdojo primary package which broke it? Honestly I have no clue, this is a rough problem and I don't have a good solution.

Possible Solutions?

app-model missing file

This should be a quick-ish fix in app_model.dart

update load method line 121 to try catch file not found error

It'll load fine with an empty file so maybe on parse failure or no file create a default app-model and use toJson and save to fix this issue after first run.

Bitdojo

This is harder. You could try to tear out the bitdojo specific code and have a linux-specific window customization use some other method.

lib/_utils/native_window_utils/window_utils_native.dart update the output for Platform.isLinux conditional branch
lib/_utils/native_window_utils/titlebar_wrappers/linux_title_bar.dart Pull out bitdojo appWindow usage.

Thanks everyone, we're currently looking into this. As mentioned we have a custom fork of bitsdojo we're looking to merge, at that point hopefully this will clear up.

The save file is a bit of a red herring, it's expected that on first launch there is nothing to load, and we're just printing this error. Will remove that so there's less confusion.
