$ hover build --help 
Flags:
      --opengl string       The OpenGL version specified here is only relevant for external texture plugin (i.e. video_plugin).
                            If 'none' is provided, texture won't be supported. Note: the Flutter Engine still needs a OpenGL compatible context. (default "3.3")

OpenGL is used in 2 way.

One: through GLFW, used to draw your flutter app handle event, etc…
Two: through OpenGL-bindings directly, ONLY for textures (as the above flag description says). But the OpenGL-bindings version used here affect GLFW internally.

By default, we use GLFW/3.2 and OpenGL-bindings 3.3, so your system must be compatible with those versions (at least OpenGL 3.3 or above).

But if you don’t have support for OpenGL 3.3. you could use the --opengl=none flag. This flag will use OpenGL in one way:

through GLFW, used to draw your flutter app handle event, etc…
GLFW will internally choose the min OpenGL compatible version to use.
Texture plugin won’t be supported and panic the app (no OpenGL-bindings used).

@ykmnkmi I cannot go lower than 3.2:

panic: InvalidValue: Context profiles are only defined for OpenGL version 3.2 and above

OpenGL is only needed for texture plugins (i.e.: video_player). I’m working on adding hover flag to choose at compile-time whether or not you want to support texture plugins (and thus, having to compile go-flutter with a reference to OpenGL)

the flag will look somethings like this hover run --opengl=none

@Drakirus I’ll try ASAP
