Common operators in Dart

1. Arithmetic Operators

• + : Addition
• - : Subtraction
• * : Multiplication
• / : Division (returns a double)
• ~/ : Integer division (returns an int)
• % : Modulus (remainder)

2. Equality and Relational Operators

• == : Equal to
• != : Not equal to
• > : Greater than
• < : Less than
• >= : Greater than or equal to
• <= : Less than or equal to

3. Type Test Operators

• is : Checks if the object is of a specified type
• is! : Checks if the object is not of a specified type

4. Assignment Operators

• = : Simple assignment
• += : Add and assign
• -= : Subtract and assign
• *= : Multiply and assign
• /= : Divide and assign
• ~/= : Integer divide and assign
• %= : Modulus and assign

5. Logical Operators

• && : Logical AND
• || : Logical OR
• ! : Logical NOT

6. Bitwise and Shift Operators

• & : Bitwise AND
• | : Bitwise OR
• ^ : Bitwise XOR
• ~ : Bitwise NOT
• << : Left shift
• >> : Right shift

7. Conditional (Ternary) Operator

• condition ? expr1 : expr2 : If the condition is true, evaluates expr1; otherwise, evaluates expr2.

8. Null-aware Operators

• ?? : Provides a default value if the expression on the left is null
• ??= : Assigns a value to a variable only if that variable is null
• ?. : Calls a method or accesses a property only if the object is not null

These operators help perform various operations in Dart for arithmetic, comparisons, logical evaluations, and more.
