Variable is used to store the value and refer the memory location in computer memory. When we create a variable, the Dart compiler allocates some space in memory. The size of the memory block of memory is depended upon the type of variable. To create a variable, we should follow certain rules. Here is an… Continue reading Dart Variable

The data types are the most important fundamental features of programing language. In Dart, the data type of the variable is defined by its value. The variables are used to store values and reserve the memory location. The data-type specifies what type of value will be stored by the variable.
