Is there any ternary operator for just single if condition in dart?
No.
The conditional operator ?
/:
in Dart requires all three operands.
It does so because all expressions must have a value, and if you could do just e1 ? e2
, then the expression has no value if e1
is false.
It's not impossible to conceive of a binary conditional operator where the missing expression defaults to null
, say (e1?:elseExpression)
or (e1?thenExpression:)
, but then you can also just write the null
, and saving four letters is probably not worth the potential loss of readability.
Ob-nitpick. The conditional operator in Dart is one of two ternary operators (operators requiring three operands, like binary operators require two operands), the other ternary operator being []=
.

In dart we have plenty of ternary operators. But do we have one ternary operator just for if condition?
Example
In condition
if (num == 1){ print(true); } else { print(false); }
In ternary
print(num == 1 ? true : false);
So do we have any ternary operator just for true condition like above example?
if (num == 1) { print(true); }
