[Flutter] 화면 터치하면 키보드가 내려가도록 하기

DismissKeyboard 클래스 생성

class DismissKeyboard extends StatelessWidget {
  final Widget child;

  const DismissKeyboard({Key? key, required this.child}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () {
        FocusScopeNode currentFocus = FocusScope.of(context);
        if (!currentFocus.hasPrimaryFocus &&
            currentFocus.focusedChild != null) {
          FocusManager.instance.primaryFocus?.unfocus();
        }
      },
      child: child,
    );
  }
}

기능이 필요한 곳에 사용하면된다 !!

@override
  Widget build(BuildContext context) {
    return DismissKeyboard(
      child: Scaffold(
        appBar: CGAppBar(
          leading: IconButton(
            icon: SvgPicture.asset(CGIcon.icArrowLeft),
            onPressed: () {
              Navigator.of(context).pop();
            },
          ),
        ),
        body: SafeArea(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            crossAxisAlignment: CrossAxisAlignment.stretch,
            children: [
              const Text('닉네임을 입력해주세요.', style: CGTextStyle.title2),
              CustomLineTextField(
                  controller: TextEditingController(),
                  hintText: '닉네임은 8글자 이하로 설정해주세요.')
            ],
          ),
        ),
      ),
    );
  }
