  return Scaffold(
    bottomNavigationBar: Container(
      height: 56,
      margin: EdgeInsets.symmetric(vertical: 24, horizontal: 12),
      child: Row(
        children: <Widget>[
          Container(
            width: 66,
            color: Colors.green,
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              children: <Widget>[Icon(Icons.chat, color: Colors.white), Text("CHAT", style: TextStyle(color: Colors.white))],
            ),
          ),
          Container(
            width: 66,
            color: Colors.green,
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              children: <Widget>[Icon(Icons.notifications_active, color: Colors.white), Text("NOTIF", style: TextStyle(color: Colors.white))],
            ),
          ),
          Expanded(
            child: Container(
              alignment: Alignment.center,
              color: Colors.red,
