Hi, damywise! I don't have MacOS so I can't test it, but I think you can use it by installing the static library (libsdl2.dylib and more) on MacOS.

You can do it by using Homebrew.

brew update brew upgrade brew doctor

brew install sdl2 brew install sdl2_image brew install sdl2_ttf brew install sdl2_mixer brew install sdl2_net

Hello there, sorry it took so long, but I have tried installing them and it's still not working. The error is still the same

damywise commented 1 year ago

Good news, I've finally found a fix that loads the sdl2 library: modify dylib.dart as follows, inspired by dart_sdl package

//...
    case 'macos':
      header = 'lib';
      extension = '.dylib';

      if (!File(header + mark + extension).existsSync()) {
        header = '';
        extension = '.framework/$mark';
      }
      break;
 //...

Bad news is, it still doesn't work. Error at this specific line https://github.com/sansuido/sdl2/blob/bbce1c6ed5af456812c0cc557f6c0ef28f3f5dd0/example/main.dart#L16-L20 (Almost same error as dart_sdl, though the audio example in dart_sdl works):

NSWindow drag regions should only be invalidated on the Main Thread!

Also I made a fork in case anyone wants to test it out https://github.com/damywise/sdl2. If it the libraries doesn't load, just put the *.framework folders to one of the paths in the error
