Record syntax. Records expressions are comma-delimited lists of named or positional fields, enclosed in parentheses: dart. var record = ('first', a: 2, b: true, 'last'); Record type annotations are comma-delimited lists of types enclosed in parentheses. You can use record type annotations to define return types and parameter types.

The value null (Null) This support includes the ability to create objects using literals. For example, 'this is a string' is a string literal, and true is a boolean literal. Because every variable in Dart refers to an object—an instance of a class—you can usually use constructors to initialize variables. Some of the built-in types have ...

Here, the "null check operator" acts as a condition to either evaluate the left-hand side or right-hand-side value. It will first check if the variable "websiteName" is not null then it will return it value. But if its null, then it will return "DartAndFlutter". You can also use it in variable assignment as shown below.

num operator % (num other) Euclidean modulo of this number by other. Returns the remainder of the Euclidean division. The Euclidean division of two integers a and b yields two integers q and r such that a == b * q + r and 0 <= r < b.abs(). The Euclidean division is only defined for integers, but can be easily extended to work with doubles.

The Basic. The conditional (ternary) operator is just a Dart operator that takes three operands: a condition followed by a question mark (?), then an expression to execute if the condition is truthy followed by a colon (:), and finally the expression to execute if the condition is falsy. The syntax: condition ? exprIfTrue : exprIfFalse. Where:

Contents. Dart is an object-oriented language with classes and mixin-based inheritance. Every object is an instance of a class, and all classes except Null descend from Object. Mixin-based inheritance means that although every class (except for the top class, Object?) has exactly one superclass, a class body can be reused in multiple class ...

Here, math represents the dart:math library, and math.pow(2, 53) is 2 53. On the web, integers lose precision past 53 bits. In particular, 2 53 and 2 53 +1 map to the same value due to truncation. On native, these values can still be differentiated because native numbers have 64 bits—63 bits for the value and 1 for the sign.

Test whether this value is numerically equal to other. If both operands are doubles, they are equal if they have the same representation, except that: zero and minus zero (0.0 and -0.0) are considered equal. They both have the numerical value zero. NaN is not equal to anything, including NaN. If either operand is NaN, the result is always false.
