I was assigned to run a mobile application with the Flutter framework. But I don't understand how to use "title" in the navbar item, of course with style. Therefore, I want to ask, "How do I fix the error in the code?" and how to include a proper "title" parameter in Flutter?

CodePudding user response：

instead of defining the title on BottomNavigationBarItem because it doesn't exist anymore, you should use the label which accepts a String, like this:

// ... 
BottomNavigationBarItem(
          icon: Icon(Icons.home),
          label: 'Home', // use this
        ),
// ...

CodePudding user response：

In updated flutter version title is migrated with label.

Use it like :

BottomNavigationBarItem(icon: Icon(Icons.home), label: 'Home')

CodePudding user response：

title parameter is deprecated by the flutter, either use a previous flutter version or change your title parameter to label which accepts only string as a parameter.

BottomNavigationBarItem(
          icon: Icon(Icons.home),
          title: const Text('Home') // remove this and replace it with
          label: 'Home', // this instead...
        ),

For styling the text use customized theme in material app for example:

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData.dark().copyWith(
        bottomNavigationBarTheme: BottomNavigationBarThemeData(), // edit this object
      home: const HomeScreen(),
      ),
    );
  }
}
