Uncaught Web Exception

For web build (in debug) I encountered the following uncaught exception:

NotAllowedError, Failed to execute 'request' on 'WakeLock': The requesting page is not visible

In the stack, this code gets highlighted:

```
@override
Future toggle({required bool enable}) async {
// Make sure the JS library is loaded before calling it.
await _jsLoaded;

wakelock_plus_web.toggle(enable);
}
```
