사이드 메뉴바를 펄럭이는 방법은?

사이드 메뉴바를 펄럭이는 방법은?

나는 설레이는 것이 처음이고 사이드 메뉴를 열기 위해 메뉴 버튼을 만들었지만, 그러기 위해서는 도움이 필요하다.

구현하는 것을 도와주거나 작동하는 방법에 대한 코드를 안내해줄 수 있는 사람이 있나요? 정말 감사합니다!

제 코드는 다음과 같습니다.

  Widget _icon(IconData icon, {Color color = LightColor.iconColor}) {
return Container(
  padding: EdgeInsets.all(10),
  decoration: BoxDecoration(
      borderRadius: BorderRadius.all(Radius.circular(13)),
      color: Theme.of(context).backgroundColor,
      boxShadow: AppTheme.shadow),
  child: Icon(
    icon,
    color: color,
  ),
);
}

주:

    class _MainPageState extends State<MainPage> {
  bool isHomePageSelected = true;
  Widget _appBar() {
    return Container(
      padding: AppTheme.padding,
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: <Widget>[
          RotatedBox(
            quarterTurns: 4,
            child: _icon(Icons.menu, color: Colors.black54),
          ),
          ClipRRect(
            borderRadius: BorderRadius.all(Radius.circular(13)),
            child: Container(
              decoration: BoxDecoration(
                color: Theme.of(context).backgroundColor,
                boxShadow: <BoxShadow>[
                  BoxShadow(
                      color: Color(0xfff8f8f8),
                      blurRadius: 10,
                      spreadRadius: 10),
                ],
              ),


            ),
          )
        ],
      ),
    );
  }

다음 코드 사용:

Scaffold.of(context).openDrawer();

권장되는 방법은 전화하는 것입니다.

샘플 코드:

drawer: const NavBar(), // Your nav bar here
appBar: AppBar(
          title: "Home".appBarText(),
          leading: Builder(builder: (context) {
            return IconButton(
              icon: const Icon(Icons.menu),
              onPressed: () {
                Scaffold.of(context).openDrawer(); 
              },
        );
