The macos implementation of [connectivity].
To use this plugin in your Flutter Web app, simply add it as a dependency in your pubspec.yaml alongside the base connectivity plugin.
(This is only temporary: in the future we hope to make this package an “endorsed” implementation of connectivity, so that it is automatically included in your Flutter macos app when you depend on package:connectivity_macos.)
This is what the above means to your pubspec.yaml:
... dependencies: ... connectivity: ^0.4.6 connectivity_macos: ^0.0.1 ...
Once you have the connectivity_macos dependency in your pubspec, you should be able to use package:connectivity as normal.
