flutter showDialog弹窗

可以弹窗嵌套一个类

          showDialog(context: context,builder: (context) => BoxDialog(getUserShake.shakeBoxId)).then((value) => dialogClose(value));

也可以直接写布局

  showDialog(context: context,builder: (context) {return Center(child: SizedBox(child: Stack(alignment: Alignment.topCenter, children: [Container(decoration: BoxDecorationUtil().setFillBoxDecoration(Colors.white, 14.0),margin: const EdgeInsets.only(top: 35, right: 52, left: 52),child: Column(mainAxisSize: MainAxisSize.min, children: [Container(margin: const EdgeInsets.only(top: 54, bottom: 20, right: 20, left: 20),child: ContentTextBlod('对方设定视频通话需要打赏', 14.0, Colors.black,FontWeight.normal)),Row(mainAxisSize: MainAxisSize.min,crossAxisAlignment: CrossAxisAlignment.center,children: [const Image(image: AssetImage('assets/images/icon_diamond.png'),width: 16,height: 16),RightPadding(2),ContentTextBlod('30/分钟', 14.0, Colors.black, FontWeight.normal)]),GestureDetector(onTap: () {MyRouter.pop(context);callingPhone(callingScenes, false);},child: Container(height: 40,margin: const EdgeInsets.only(top: 10, right: 40, left: 40, bottom: 15),alignment: Alignment.center,decoration: BoxDecoration(//背景color: CommonColors.getColor27D6BC,//设置四周圆角 角度borderRadius:const BorderRadius.all(Radius.circular(20))// borderRadius: const BorderRadius.only(//     bottomLeft: Radius.circular(14),//     bottomRight: Radius.circular(14))),child: ContentTextBlod('继续', 17.0, Colors.white, FontWeight.w800))),Row(mainAxisSize: MainAxisSize.min,crossAxisAlignment: CrossAxisAlignment.center,children: [const Image(image: AssetImage('assets/images/icon_diamond.png'),width: 16,height: 16),RightPadding(2),ContentTextBlod('不再提示', 14.0, Colors.black, FontWeight.normal)]),TopPadding(15)]))])));});

如果是从底部弹起的弹窗

 showChatDialog(matchUserBean) {showModalBottomSheet(shape: const RoundedRectangleBorder(borderRadius: BorderRadius.only(topLeft: Radius.circular(24), topRight: Radius.circular(24))),isScrollControlled: true,enableDrag: false,backgroundColor: CommonColors.getColorF5F8F5,context: context,builder: (context) =>ChatMatchDialog(matchUserBean, PlayDisposition.SLIDING_MATCH));//ChatMatchDialog是一个类}

底下弹窗showModalBottomSheet
嵌套类

      showModalBottomSheet(shape: const RoundedRectangleBorder(borderRadius: BorderRadius.only(topLeft: Radius.circular(24), topRight: Radius.circular(24))),isScrollControlled: true,enableDrag: false,backgroundColor: CommonColors.getColorF5F8F5,context: context,builder: (context) => MatchFriendDialog(2,PlayDisposition.BOTTLE,MatchUserBean(userID: _unlockUser?.userInfo?.userId,nickName: _unlockUser?.userInfo?.nickname,avatar: _unlockUser?.userInfo?.avatar,// avatarThumb:_unlockUser?.userInfo?.avatarThumb,sign: _unlockUser?.userInfo?.sign,sex: _unlockUser?.userInfo?.sex,birthday: _unlockUser?.userInfo?.birthday,vipLevel: _unlockUser?.userInfo?.vipLevel// vipExpirationTime:_unlockUser?.userInfo?.vipExpirationTime)));

直接写布局

    showModalBottomSheet(shape: const RoundedRectangleBorder(borderRadius: BorderRadius.only(topLeft: Radius.circular(32), topRight: Radius.circular(32))),isScrollControlled: true,backgroundColor: Colors.white,context: context,builder: (context) {return ListView.separated(shrinkWrap: true,itemBuilder: (context, index) {if (index == 0) {return Ink(decoration: const BoxDecoration(borderRadius: BorderRadius.only(topLeft: Radius.circular(32),topRight: Radius.circular(32))),child: InkWell(onTap: () {onPress(0);Navigator.pop(context, true);},borderRadius: const BorderRadius.only(topLeft: Radius.circular(32),topRight: Radius.circular(32)),child: SizedBox(height: 72,child: Row(mainAxisAlignment: MainAxisAlignment.spaceEvenly,children: [Align(alignment: Alignment.center,child: Text(contents[index],style: TextStyle(fontSize: Dimens.fontSize_16,color: (selectIndex>0 &&selectIndex == index)? CommonColors.getColorE97676: CommonColors.getColor181818),),),],),),));}return InkWell(onTap: () {onPress(index);Navigator.pop(context,true);},child: SizedBox(height: index == 1 ? 55 : 64,child: Row(mainAxisAlignment: MainAxisAlignment.spaceEvenly,children: [Align(alignment: Alignment.center,child: Text(contents[index],style: TextStyle(fontSize: Dimens.fontSize_16,color: (selectIndex>0 &&selectIndex == index)? CommonColors.getColorE97676: CommonColors.getColor181818),),),]),));},separatorBuilder: (context, index) {return Divider(height: 3,color: CommonColors.getColorDivider_F7F7F7,);},itemCount: contents.length);});
