flutter-app-demo's Issues

AppImageKit and gpg

Hi, you should add those kind of resources in the documentation as tools to release the app 😎

[suggestion] add to the readme that this demo requires Ubuntu font family on linux?

My linux distro (manjaro) didn't have the Ubuntu font family installed by default and i thought the demo was broken. Perhaps this should be mentioned in the readme.

Traceback (most recent call last):

Demo segfaults on start up after FlutterEngineRun

Distro: Arch Linux
Kernel ver: 5.3.8
Flutter ver: 1.10.16-pre.93
Rust ver: 1.38.0

This also occurs for me in the template.

Initially I had though that the problem was isolated to window creation, but I threw in thread sleeps to narrow down where the cause of the problem was and it looks like a deadlock is happening after flutter_engine_sys::FlutterEngineRun is run within the engine. The segfault happens directly after that function when calling thread::sleep.

dmesg output:
io.flutter.ui[63336]: segfault at 0 ip 00007f4e900d966c sp 00007f4e8b2dc0d0 error 4 in libflutter_engine.so[7f4e8fc9d000+a20000]
This might indicate a null pointer?

It might be more appropriate to put this in the flutter-rs repo.

Snap install documentation missing

Hi, you should add it to the documentation

sudo snap install ~/Downloads/flutter-app-demo_0.3.0.snap --classic --dangerous

Latest commit breaks the demo

5cf2df4 seems to break the demo. Reverting it allowed the demo to launch.

expected reference, found struct `std::string::String`
help: consider borrowing here: `&CHANNEL_NAME.to_string()`
