The plugin is to resolve Android's content URI that is often used by Content providers.
Add this to your package's pubspec.yaml file and execute flutter pub get:
dependencies:
content_resolver: ^0.3.1
The following fragment is a use case with app_links to receive content:...
URI content:
_appLinks = AppLinks(onAppLink: (uri) async {
// If the data is some image, you can pass the data directly to Image.data or something.
final Content content = await ContentResolver.resolveContent(uri);
...
});
The following fragment illustrates how to write data to content:...
URI:
final data = Uint8List.fromList(utf8.encode('Hello World'));
await ContentResolver.writeContent(uri.toString(), data);
...
Please note that if the URI is not writable, the code throws certain exception.
