SingleChildScrollView(
    reverse: true,
    child: Container(
      padding: const EdgeInsets.fromLTRB(30.0, 30.0, 30.0, 150.0),
      child: AvatarGlow(
        glowColor: Colors.blue,
        endRadius: 90.0,
        duration: Duration(milliseconds: 2000),
        repeat: true,
        showTwoGlows: true,
        repeatPauseDuration: Duration(milliseconds: 100),
        child: Material(
          // Replace this child with your own
          elevation: 8.0,
          shape: CircleBorder(),
          child: CircleAvatar(
            backgroundColor: Colors.grey[100],
            child: Text("abc"),
            radius: 40.0,
