       theme: ThemeData(
         scaffoldBackgroundColor: Constants.scaffoldBackgroundColor,
         visualDensity: VisualDensity.adaptivePlatformDensity,
         textTheme: GoogleFonts.poppinsTextTheme(),
       ),
       initialRoute: "/",
       onGenerateRoute: _onGenerateRoute,

   );
 }
}

Try using a builder instead.

From the flutter_screenutil readme:

    return ScreenUtilInit(
      designSize: const Size(360, 690),
      minTextAdapt: true,
      splitScreenMode: true,
      builder: (context , child) {
        return MaterialApp(
          debugShowCheckedModeBanner: false,
          title: 'First Method',
          // You can use the library anywhere in the app even in theme
          theme: ThemeData(
            primarySwatch: Colors.blue,
            textTheme: Typography.englishLike2018.apply(fontSizeFactor: 1.sp),
          ),
          home: child,
        );
      },
      child: const HomePage(title: 'First Method'),
    );

In which widget are you trying to call child?

CodePudding user response：

You must need to declare home inside MaterialApp and give your initial page to that.
