I've debugged the issue and came to a problem in the audio_service.dart at line 969. In this line the the File object has been used from dart.io library which is not supported in the Flutter web. Am I using the library in a wrong way or is this a bug?

I'm encountering the following error often, though it's inconsistent and I can't figure out why. I'm using tester as instructed for Flutter Integration tests.
Test Code:
testWidgets('should create and save simulation', (tester) async {
await startApp(tester, app);
await login(tester);
await navigateTo(NavPage.SIMULATOR, tester);
String scenarioName = "CreateAndSaveScenario";
await createScenario(scenarioName, tester);
expect(find.text("CRQ Simulator"), findsWidgets);
expect(find.text("Edit Scenario"), findsWidgets);
expect(find.text(scenarioName), findsWidgets);
Finder fairSwitchFinder = find.byType(Switch);
tester.tap(fairSwitchFinder);
await navigateTo(NavPage.SIMULATOR, tester);
expect(find.byType(ListTile), findsOneWidget);
expect(find.text(scenarioName), findsOneWidget);
});
Error:

The test description was:
should create and save simulation
═════════════════════════════════════════════════════════════════
end of failure 1
I was expecting the tester to navigate, but after the fairSwitchFinder tap, it seems to not be able to do anything because the lineMatch is null? The error is not very descriptive
Okay, I figured this out fairly quickly afterward. Surprised there weren't any answers up, but hopefully this question shows up in searches now.
I was missing an await.
I changed
tester.tap(fairSwitchFinder); to await tester.tap(fairSwitchFinder); and it fixed it.
i am trying to use LocationService () in flutter web app, but it gives me the error:
Error: XMLHttpRequest error.

Goodmorning, I'm trying to use keycloak and flutter but unfortunally when i ask the token to keycloak he gives me an XMLHttpRequestError. I use thos method to ask:
Future<String> makeTokenRequest(String url,Map<String,String>params) async {
try {
print("arrivato in _restManager");
await post(url, body: params).then((result) {
print(result.toString());
});
}catch(e){
throw e;
}
}
Future<String> getToken(String email,String password) async {
try{
Map<String,String> params=Map();
params["grant_type"]="password";
params["client_id"]="myclient";
params["client_secret"]="6be8e24b-9c81-482e-99ac-05ed154e572e";
params["username"]="cappuccio";
params["password"]="franco";
String result=await _restManager.makeTokenRequest("http://localhost:8080/auth/realms/PiattaformaPrenotazioni/protocol/openid-connect/token",params);
}catch(e){
throw e;
}
}
those two methods are just toys that i'm using to learn, i know that probably they aren't the best way. I read that if i don't specify anything post method will use urlencoded and with a Map<String,String> body he will encode it right.
The Error i get is this:
Error: XMLHttpRequest error.

I had the same problems, I resolved it setting * in keycloak/your client/Valid redirect URIs
I would like to know if it is possible to load data in memory from a file stored in firebase storage?
My goal is to open the file and show the data in the browser, without downloading it to the computer. Firebase is configured correctly in my project, I can upload and get URL.
I tried using the command below, but I get an error:
await FirebaseStorage.instance
.ref()
.child(TabelaIbptConsts.PATH_TABELAS)
.child('MG.csv')
.getData()
.then((value) => print(value));
I get the error below:
Error: XMLHttpRequest error.

Your URL is missing a scheme eg: http://
So try adding a scheme like http://example.com/login
