Question

Accepted Answer

## Overview Dart provides a comprehensive set of operators. Here is a complete reference of all operator types available in Dart/Flutter. --- ## Complete Operator Reference ### Arithmetic ```dart + // Addition - // Subtraction * // Multiplication / // Division (returns double) ~/ // Integer division % // Modulo -e // Unary negation ``` ### Increment / Decrement ```dart ++x // Pre-increment x++ // Post-increment --x // Pre-decrement x-- // Post-decrement ``` ### Relational / Comparison ```dart == // Equal != // Not equal > // Greater than < // Less than >= // Greater than or equal <= // Less than or equal ``` ### Logical ```dart && // Logical AND || // Logical OR ! // Logical NOT ``` ### Bitwise ```dart & // Bitwise AND | // Bitwise OR ^ // Bitwise XOR ~ // Bitwise NOT << // Left shift >> // Right shift >>> // Unsigned right shift (Dart 2.14+) ``` ### Assignment ```dart = // Assign += // Add and assign -= // Subtract and assign *= // Multiply and assign /= // Divide and assign ~/= // Integer divide and assign %= // Modulo and assign &= // Bitwise AND and assign |= // Bitwise OR and assign ^= // Bitwise XOR and assign <<= // Left shift and assign >>= // Right shift and assign ??= // Assign if null ``` ### Type Test ```dart is // Type check (returns bool) is! // Negative type check as // Type cast ``` ### Null-Aware ```dart ?. // Conditional member access ?? // Null coalescing (or default) ??= // Assign if null ! // Null assertion (force unwrap) ...? // Null-aware spread ``` ### Collection / Cascade ```dart [] // List/Map subscript access []= // Subscript assign .. // Cascade (chain calls on same object) ?.. // Null-aware cascade ... // Spread operator in collections ``` ### Conditional ```dart ? : // Ternary: condition ? ifTrue : ifFalse ``` --- ## Quick Examples ```dart // Type value is String // true/false value as String // cast // Cascade Paint()..color = Colors.red..strokeWidth = 2; // Null-aware cascade user?..name = 'Alice'..save(); // Spread final list = [...list1, ...list2]; // Subscript final first = list[0]; map['key'] = 'value'; ``` > **Most Used in Flutter:** `?.`, `??`, `!`, `==`, `!=`, `&&`, `||`, `??=`, `...` (spread), `..` (cascade).
