there is a row of widgets in flutter, I want it to be visible on meeting certain condition, if the condition is true it should not be visible and if condition is false it should be visible

below is the code

```
Container(
      child: Row(
        children: <Widget>[
          // Button send image
         Text("Text1"),
         Text("Text2"),
         Text("Text3"),
         Text("Text4"),

        ],
      ),
      width: double.infinity,
      height: 50.0,
      decoration: BoxDecoration(border: Border(top: BorderSide(color: greyColor2, width: 0.5)), color: Colors.white),
    )

```

Conditions you can say for instance

```
int a==b

```

if true not visible , if false visible

How may I achieve it?
