This is a test app for manual testing and automated integration testing of this platform implementation. It is not intended to demonstrate actual use of this package, since the intent is that plugin clients use the app-facing package.
Unless you are making changes to this implementation package, this example is very unlikely to be relevant.
This package uses package:integration_test to run its tests in a web browser.
See Plugin Tests > Web Tests in the Flutter wiki for instructions to setup and run the tests in this package.
Check flutter.dev > Integration testing for more info.
