In this post, we will learn about the Dart Switch Case Statement and its application with a practical example.

In this post, we'll learn if..else..if statement allows us add alternative set of test conditions in if..else statement using else-if and single else statements for if condition.

.

A conditional/decision-making construct evaluates a condition before the instructions are executed.

In this post, we'll learn how can declaring variables in Dart.

Following the trend on modern OOP languages, Dart provides a null-safe syntax that evaluates and returns an expression according to its null/non-null value.

Dart provides bitwise and shift operators to manipulate individual bits of numbers, usually with the num type

Logical operators in Dart are the common operators applied to bool operands; they can be variables, expressions, or conditions. Additionally, they can be combined with complex
expressions by combining the results of the expressions. The provided logical operators are as follows:

The Type test operators are used for checking types at runtime.

Equality and Relational operators are used to evaluating a comparison between two operands. The result of a relational operation is a Boolean value that can only be true or false. Relational Operators are also referred to as Comparison operators.

The increment and decrement operators are also common operators and are implemented in number type, as follows:


There is a writing error in formulas (c) and (b) . This is a correction
c) S* S=S*
so S*=c S=S*c
b) S- S=S-
so S-=a S=S-a

Dart comes with many typical operators that work like many languages; this includes the
following:

An operator is a special symbol that is used to carry out some specific operation on its operand. In Dart, we have rich set of built in operators to carry out different type of operations. There are operators for assignment, arithmetic operations, logical operations and comparison operations etc. Operators can be used with many types of variables or constants, but some of the operators are restricted to work on specific data types. Most operators are binary, meaning they take two operands, but a few are unary and only take one operand.
