If you are attempting to put a String variable inside another static String you can do the following for simple variables: String firstString = ‘sentence’; String secondString = ‘This is a $firstString’; Which will output This is a sentence .

There is no need to create a class object to access a static variable or call a static method: simply put the class name before the static variable or method name to use them .

The basic building block of information in your Dart program will be variables. Anytime you’re working with data in an app, you can store that data in variables. For example, if you’re building a chat application, you can use variables to refer to chat messages or a user. Variables store references to these values.

This is done with this code snippet:

Advertisements. A variable is “a named space in the memory ” that stores values. In other words, it acts a container for values in a program. Variable names are called identifiers.

When defined with an initial value, var is int in this case. dynamic: can change TYPE of the variable, & can change VALUE of the variable later in code . var: can’t change TYPE of the variable, but can change the VALUE of the variable later in code.
