The macos implementation of url_launcher.
To use this plugin in your Flutter macos app, simply add it as a dependency in your pubspec.yaml alongside the base url_launcher plugin.
(This is only temporary: in the future we hope to make this package an “endorsed” implementation of url_launcher, so that it is automatically included in your Flutter macos app when you depend on package:url_launcher.)
This is what the above means to your pubspec.yaml:
... dependencies: ... url_launcher: ^0.5.4+8 url_launcher_macos: ^0.1.0 ...
Once you have the url_launcher_macos dependency in your pubspec, you should be able to use package:url_launcher as normal.
