No rendering on Android

No rendering on Android (tested on Snapdragon 8 sGen3), AdrenoVK gives some warnings about unknown struct types

blacklisting for angle ( https://github.com/Knightro63/flutter_angle/blob/main/flutter_angle/android/src/main/java/org/fluttergl/flutter_angle/FlutterAnglePlugin.java "isBlacklistedForAngle" ) for my device fixed the issue.
Same issue also occurs on other devices like on the Mediatek Dimensity 7025.

Also, is there a specific version of angle this plugin relies on? was trying to add prebuilt binaries for arm64 but using prebuilt binaries for example from chrome don't seem to work (eg. libGLESv2.dll, libEGL.dll)

Hi @carrott2,

The .dll files should only be for Windows and it uses ANGLE from probably 2024. Android uses ANGLE or OpenGL depending on what device you are trying to use. The black listed devices are not all on there because another user was trying to use a huawei and received the error.

For Android it should automatically create the binaries in the .cxx folder from the CMake file and the .so files in debug and release.

If you want to try without ANGLE you can do angle.init(false,false);. This will run on OpenGL for Android.

Thanks for the response, for "arm64" I meant windows arm64 binaries.

Hi @carrott2,

It should work on Windows with arm devices. I am currently using it with my Lenovo X-Elite Snapdragon chip.

I see, then I must have done something wrong when compiling it (with github actions)

"\windows\flutter\ephemeral.plugin_symlinks\flutter_angle\windows\bin\lib\libGLESv2.dll.lib : warning LNK4272: library machine type 'x64' conflicts with target machine type 'ARM64'"

Hi @carrott2,

I see. I will need to make them again. I think my computer is running it through an emulator. you can try this flutter build windows --target-platform=windows-x64
I wont be able to fix it until this weekend. Sorry for the issue.
