Logical operators in dart is used to equate or combine two or more conditions. Logical operators returns value in True or False Boolean form. Using the Logical operators we can check two conditions together and performs certain task if they both are true or both false or one true one false. So in this tutorial we would learn about list of all Logical Operators in Dart Flutter Android iOS with Example.
Contents in this project Logical Operators in Dart Flutter with Example:
| S.NO. | Operator Sign | Operator Name |
| 1. | && | Logical AND |
| 2. | || | Logical OR |
| 3. | !expr | Logical Not |
Explanation:
1. Logical AND(&&) : Logical AND return True if both given conditions are True. If any of given condition are false then it will return False.
Example:
|
1 2 3 4 5 6 7 8 9 10 |
void main() { bool a, b; a = true ; b = false ; print(a && b); // Result is False; } |
2. Logical OR( || ) : Logical OR return True if any of given condition are True.
Example:
|
1 2 3 4 5 6 7 8 9 10 |
void main() { bool a, b; a = true ; b = false ; print(a || b); // Result is True ; } |
3. Logical NOT ( ! ) : Logical NOT operator reverse the given condition and If given condition is True then it will return us False and if the given condition is False then it will returns us True.
Example:
|
1 2 3 4 5 6 7 8 9 |
void main() { bool a, b; a = true ; b = false ; print(!a); // Result is False ; } |
