    If you like to use SingleChildScrollView, remove Expanded from Column widget, You can think like, SingleChildScrollVew provides infinite height and Exapanded widget is trying to get infinite and this cause issue.

    You can follow this way

    showModalBottomSheet(
    shape: RoundedRectangleBorder(
      borderRadius: BorderRadius.circular(15.0),
    ),
    context: context,
    builder: (context) {
      return SingleChildScrollView(
        child: Padding(
          padding: const EdgeInsets.all(20.0),
          child: Column(
            children: [
              Column(
                children: [
                  Row(
                    children: [
                      // CircleAvatar(
                      //   radius: 22,
                      //   backgroundImage: NetworkImage(
                      //       '${SocialCubit.get(context).userModel!.image}'),
                      // ),
                      SizedBox(
                        width: 15,
                      ),
                      Container(
                        decoration: BoxDecoration(
                          borderRadius: BorderRadius.circular(10),
                          color: Colors.grey[350],
                        ),
                        child: Padding(
