GetMaterialApp home widget is being called multiple times-CodePudding

I'm using GetMaterialApp i.e. GetX stage management.

The home widget is a FutureBuilder that checks user login and shows screens accordingly.

In the builder of the FutureBuilder I added a print statement and when I run the app it's being printed more than one time.

Is this fine or do I need to make some changes such that it's called only once?

Is this the behaviour of FutureBuilder or GetMaterialApp?

Below is my home widget code

home: FutureBuilder(
        future: isUserLoggedIn(),
        builder: (c, r) {
          print("LOOK");
          print(r.data);
          bool isLoggedIn = r.data == null ? false : r.data as bool;

          if (isLoggedIn) {
            return const DashboardScreen();
          }
          return const LoginScreen();
        },
      ),

Following is the output printed

I/flutter (29328): LOOK
I/flutter (29328): null
[GETX] Instance "ImageFetcher" has been created
I/flutter (29328): LOOK
I/flutter (29328): true
I/flutter (29328): LOOK
I/flutter (29328): true

CodePudding user response：

that is the behavior of FutureBuilder, you can see some references of this here:

Flutter FutureBuilder gets constantly called

it is not related to GetX
