My male and female toggle button is not working in bmi calculator-CodePudding

Since i had moved my Gesturedetector widgit into reusable_child.dart file my app became non functional. Please someone help me to fix the issue of male female toggle

Previously when then entire code was in one file(i.e BODY.dart) it was working properly this issue came after i created sepearte dart files for each

const double bottomContainerHeight = 80.0;
const Color containerColours = Color(0xFF1D1E33);
const Color inactiveContainerColor = Color(0xFF111328);

enum GenderType {
  MALE,
  FEMALE,
}

class BODY extends StatefulWidget {
  const BODY({Key? key}) : super(key: key);

  @override
  _BODYState createState() => _BODYState();
}

class _BODYState extends State<BODY> {
  GenderType selectedGender = GenderType.MALE;
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      drawer: AppDrawer(),
      appBar: AppBar(

CodePudding user response：

the issue is in your FEMALE ReusableCard's onPress

onPress: () {
  selectedGender = GenderType.FEMALE;
},

you forgot to add setState here as well

onPress: () {
  setState(() {
    selectedGender = GenderType.FEMALE;
  });
},
