GFLW Window creation failed

[drexhacker]

Am working on a desktop app with go flutter but unfortunately the Application failed to run on my old pc with OpenGL 2.1 Mesa 18.X.X (Graphics Card: Intel Cooperation 4 Series Graphics Controller rev 03), Now am asking is there a way to build this old pc of mine

[drexhacker]

Maybe a way to configure gflw to support OpenGL 2.1 would work

[pchampio]

hover build XXX --opengl=none (note: texture plugin wont work anymore, but we don't officially have any of them.. so it's no issue)

[drexhacker]

@pchampio its still failin

[pchampio]

What's the terminal output ? (bins must be build with hover build XXX --opengl=none --debug)
I'm afraid flutter might not support such a old version.

creating glfw window: VersionUnavailable: EGL: Failed to create context: Arguments are inconsistent

I don't think I can help you that much.
It's my first time seeing this error.

Maybe can you try to workout the glfw flags ?

can you try to modify the glfw flags here (especially line 145):
