Chinese input method don't work on Linux

[X-Wei]

Description

I'm on Debian Linux, and use fcitx for typing Chinese (sudo apt install fcitx-googlepinyin).

But with go-flutter-desktop the Chinese I typed were just omitted, I also see nothing in the terminal output while doing hover run.

Hover doctor

Seems there's no hover doctor command? I ran hover upgrade to get the latest version and this problem still exists.

# Operation system: Linux (Debian)
$ hover upgrade
hover: 'go-flutter' is on version: v0.35.1

hover upgrade only updates the embedder and not hover itself. Run go get -u github.com/go-flutter-desktop/hover to upgrade hover and then run hover doctor in your project.

But without much knowledge I'd guess it's a GLFW compatability issue

Thanks @jld3103 ! I re-get the hover repo, and here's the output:

Not sure if it's relevant, I saw these errors when focusing on the text input field:

go-flutter: no method handler registered for method 'TextInput.setEditableSizeAndTransform' on channel 'flutter/textinput'
go-flutter: no method handler registered for method 'TextInput.setStyle' on channel 'flutter/textinput'

I think we are dependent upon this upstream issue: glfw/glfw#41 https://github.com/glfw/glfw/pull/658

@pchampio thanks ! So the glfw issues are in 2015 and 2018, the fixes are still not in ? When shall we expect to have the fixes in hover ?

[pchampio]

kovidgoyal has implemented IME in his glfw fork, his fork isn't event with glfw/master, I don't intent to use it. go-flutter is also using a go wrapper on top of glfw (https://github.com/go-gl/glfw), this wrapper makes applying pach to C library much harder.

If I knew was IME was and the fact that glfw did not have support for it, I would of chosen another rendering toolkit. Sadly for now we are stuck with GLFW, meaning we get the issues that comes with it..

When shall we expect to have the fixes in hover ?

I have no idea, this question has to be ask at the GLFW maintainers.

I meet same exactly the same issue as this, input chinese is invisible, all chinese charactor are invisible.

any update on this?

[pchampio]

This issue is blocked by: https://github.com/glfw/glfw/pull/658

[zw963]

is there exist any fix for some special platform? e.g. Linux? thank you
