The web implementation of url_launcher.
Please set your constraint to url_launcher_web: '>=0.1.y+x <2.0.0'
The plugin has reached a stable API, we guarantee that version 1.0.0 will be backward compatible with 0.1.y+z. Please use url_launcher_web: '>=0.1.y+x <2.0.0' as your dependency constraint to allow a smoother ecosystem migration. For more details see: https://github.com/flutter/flutter/wiki/Package-migration-to-1.0.0
To use this plugin in your Flutter Web app, simply add it as a dependency in your pubspec 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 Web app when you depend on package:url_launcher.)
This is what the above means to your pubspec.yaml:
... dependencies: ... url_launcher: ^5.1.4 url_launcher_web: ^0.1.0 ...
Once you have the url_launcher_web dependency in your pubspec, you should be able to use package:url_launcher as normal.
