![]() ![]() Let us understand a simple example about the usage of control statements and loops − Dart supports for, for.in, while and do.while loops. ![]() Loops are used to repeat a block of code until a specific condition is met. Dart supports If, If.else and switch statements. The following example illustrates the dynamic type variable −Ī decision making block evaluates a condition before the instructions are executed. The list shown above produces list.ĭynamic − If the variable type is not defined, then its default type is dynamic. Lists and Maps − It is used to represent a collection of objects. String values are specified in either single or double quotes.īooleans − Dart uses the bool keyword to represent Boolean values – true and false. Strings − It represents a sequence of characters. Numbers − It is used to represent numeric literals – Integer and Double. They are defined as below −ĭart language supports the following data types − The final and const keyword are used to declare constants. Variable is named storage location and Data types simply refers to the type and size of data associated with variables and functions.ĭart uses var keyword to declare the variable. The following code shows a simple Dart program − Dart collections can be used to replicate data structures such as arrays, generics, and optional typing. It supports programming concepts like interfaces, classes, unlike other programming languages Dart doesn’t support arrays. Dart is an object-oriented language with C-style syntax. Dart is an open-source general-purpose programming language. ![]()
