It's better to use Stack for this functionality. – Alamode

Try type BottomNavigationBarType.fixed – Polychaete

Here you go

Widget build(context) {
  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,
              child: Text("BUY NOW", style: TextStyle(fontWeight: FontWeight.bold, fontSize: 18)),
            ),
          ),
        ],
      ),
    ),
  );
}

work Nicely sir. this is working so nicely. !! god bless you sir. thanks :) :) @Alamode – Brycebryn

hey sir, @CopsOnRoad, I want to ask, maybe it seems trivial, but I really have trouble. I have 2 widgets in the row, the row is in the column, and the column is in the row like this ' row( ' ' column( ' ' row( ' ' text ' ' container ' I want to separate text and containers using spacebetween, but they still don't want to separate. are there any suggestions? here are the screenshot: imgur.com/lyfTfk7 – Brycebryn

You will have to use Expanded in your 2nd Row. – Alamode

ohh I see.. so if I use expanded they would like to separate ? well thank you so much for answering my stupid question. :)) – Brycebryn

I think they should work the way you are looking for, if not share a screenshot for what you are looking to do, I will try to help you out. – Alamode

and here are the SS imgur.com/uXJqyP5 . thanks for your kindness :) – Brycebryn

You may want to look at the concept of a BottomAppBar instead.
This bar accepts any widget as children not just BottomNavigationBarItems.

You could try this:

BottomAppBar(
      child: Row(
          mainAxisSize: MainAxisSize.max,
          mainAxisAlignment: MainAxisAlignment.spaceAround,
          children: [
            Expanded(
            child: SizedBox(
              height: 44,
              child: Material(
                type: MaterialType.transparency,
                child: InkWell(
                  onTap: () {},
                  child: Column(
                    mainAxisSize: MainAxisSize.min,
                    mainAxisAlignment: MainAxisAlignment.center,
                    children: <Widget>[
                      Icon(Icons.add, color: Colors.blue, size: 24),
                      Text("Add")
                    ],
                  ),
                ),
              ),
            ),
          ),
          ]
      ),
    )
