SDL3 for Dart #

Requirement #

ffi ^2.2.0

This library is limited to 64bit.
Since ffi is used, a dynamic library suitable for various environments is required.
image, mixer, net, and ttf are optional. Please include it if necessary.
Since sdl3gfx is included in the source, a dynamic library is not required.
For OpenGL, call require separately.

import 'package:sdl3/sdl3.dart'; // SDL3, SDL3_image, SDL3_mixer, SDL3_net, SDL3_ttf, SDL3_shadercross
import 'package:sdl3/sdl3gfx.dart'; // SDL3_gfx
import 'package:sdl3/sdl3opengl.dart'; // OpenGL

Windows requires dll files. #

SDL3.dll
SDL3_image.dll
SDL3_mixer.dll
SDL3_net.dll
SDL3_ttf.dll
SDL3_shadercross.dll

Linux requires so files. #

libSDL3.so.0
libSDL3_image.so.0
libSDL3_mixer.so.0
libSDL3_net.so.0
libSDL3_ttf.so.0
libSDL3_shadercross.so.0

Android, Fuchsia requires so files. #

libSDL3.so
libSDL3_image.so
libSDL3_mixer.so
libSDL3_net.so
libSDL3_ttf.so
libSDL3_shadercross.so

MacOS (or iOS) requires dylib files. #

libSDL3.dylib
libSDL3_image.dylib
libSDL3_mixer.dylib
libSDL3_net.dylib
libSDL3_ttf.dylib
libSDL3_shadercross.dylib

And more. #

If you want to set a library under special circumstances (example: dylib), do the following:

SdlDynamicLibraryService().set('sdl', 'YOUR_SDL3_ENVIONMENT.dylib');
SdlDynamicLibraryService().set('image', 'YOUR_SDL3_image_ENVIONMENT.dylib');
SdlDynamicLibraryService().set('mixer', 'YOUR_SDL3_mixer_ENVIONMENT.dylib');
SdlDynamicLibraryService().set('net', 'YOUR_SDL3_net_ENVIONMENT.dylib');
SdlDynamicLibraryService().set('ttf', 'YOUR_SDL3_ttf_ENVIONMENT.dylib');
SdlDynamicLibraryService().set('shadercross', 'YOUR_SDL3_shadercross_ENVIONMENT.dylib');
if (sdlInit(SDL_INIT_VIDEO)) {
  // success
}

Note #

A Dart library for accessing SDL 3 APIs using, FFI.

Windows 64bit & Linux (Tested under Windows 11 WSL2 environment)

Currently, we are providing it on an experimental basis using the dll compiled below.
