[Flutter] 모달창

바텀시트로 모달창을 만들었는데 모달창을 두개를 만드니까 다음꺼를 눌러도 이전 모달창이 그대로 남아있어서 취소를 할때 배경화면도 두번 눌러야하고 보기에도 안좋아서 어떻게 해야하나 찾아봤는데 생각보다 간단한 방법이였다...

void _modalshow(BuildContext context) {
    Navigator.pop(context);
    showModalBottomSheet(
        shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(10)),
        backgroundColor: Colors.transparent,
        barrierColor: Color(0x66303030).withOpacity(0.4),
        context: context,
        builder: (context) {
          return Stack(children: [
            Container(
              width: 360,
              height: 160,
              margin: EdgeInsets.all(1),
              decoration: BoxDecoration(
                color: Colors.white.withOpacity(0.8),
                border: GradientBoxBorder(
                  width: 1,
                  gradient: LinearGradient(
                    colors: [

                      Colors.white.withOpacity(0.2)
                    ],

                        )
                      ],
                    ),
                  ),

            Positioned(

                          'assets/image_asset/mypage/profile_select (1).png',
                          width: 28,
                          height: 42,
                        ),

                        Text(
                          '여성',
                          style: Black(16, FontWeight.w600),
                        )
                      ],
                    ),
                  ),
                )),
          ]);
        });
  }

다음으로 뜨는 모달창에 Navigator.pop(context);를 해주면 전에 모달창이 내려가진다.
생각보다 너무 간단해서 머쓱,,
