Failing to Make the keyboard push the screen up upon input in my flutter app

i want when the user wants to input something, the keyboard should push the screen up instead of creating an error, i don't want the keyboard to cover on top of the screen by setting "resizeToAvoidBottomPadding" to true is what most people suggested but it covered on top of everything instead of pushing the screen up, here is my code,

here is my code below

Container(),
              content == 'livechat'
                  ? Container(
                      child: Column(
                          mainAxisAlignment: MainAxisAlignment.start,

                          children: <Widget>[
                          Container(
