+# url_launcher_windows
+
+The Windows implementation of [`url_launcher`][1].
+
+## Backward compatible 1.0.0 version is coming
+The plugin has reached a stable API, we guarantee that version `1.0.0` will be backward compatible with `0.0.y+z`. If you use
+url_launcher_windows directly, rather than as an implementation detail
+of `url_launcher`, please use `url_launcher_windows: '>=0.0.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
+
+## Usage
+
+### Import the package
+
+This package has not yet been endorsed. Once it is you only need to add
+`url_launcher` as a dependency in your `pubspec.yaml`, but for now you
+need to include both `url_launcher` and `url_launcher_windows`.
+
+This is what the above means to your `pubspec.yaml`:
+
+```yaml
+...
+dependencies:
+  ...
+  url_launcher: ^5.5.3
+  url_launcher_windows: ^0.0.1
+  ...
+```
+
+[1]: ../url_launcher/url_launcher
