I have developed app which works on both Web and Android. I have used 'dart:html' library to check app is resumed or pause.
But when I compiling app for android its giving error.
lib/controller/home_controller.dart:2
import 'dart:html';
^
Unhandled exception:
FileSystemException(uri=org-dartlang-untranslatable-uri:dart:html; message=StandardFileSystem only supports file:* and data:* URIs)
#0 StandardFileSystem.entityForUri (package:front_end/src/api_prototype/standard_file_system.dart:34:7)
I need dart:html library to check app is resumed or paused. My code :
@override
onInit() {
super.onInit();
if (isWebApp()) {
window.addEventListener('focus', onFocus);
window.addEventListener('blur', onBlur);
} else {
WidgetsBinding.instance.addObserver(this);
}
}
void onFocus(Event e) {
didChangeAppLifecycleState(AppLifecycleState.resumed);
}
void onBlur(Event e) {
didChangeAppLifecycleState(AppLifecycleState.paused);
}
@override
void didChangeAppLifecycleState(AppLifecycleState state) {
super.didChangeAppLifecycleState(state);
printWithDateTime("111111");
if (state == AppLifecycleState.resumed) {
getEmployee();
homeDashboard();
}
}

Try adding to the import the following
import 'dart:html' as html;
Then any method used from the html package call it using html.Method()
CodePudding user response:
dart:html
can only be imported for web applications. I suggest to use universal_html in your project instead. It's a package that still uses dart:html
under the hood when using web, but allows you to import it in other platforms as well
