If we do not initialise a variable, and use a keyword "var", then it becomes "dynamically typed". example: var personName = 'John Doe' ; var personAge = 25; In the above example, we created a variable with name 'personName' and stored the value 'John Doe' in that variable. Variables in Dart: A variable name is the name assign to the memory location where the user stores the data and that data can be fetched when required with the help of the variable by calling its variable name. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[336,280],'w3schools_io-box-4','ezslot_3',113,'0','0'])};__ez_fad_position('div-gpt-ad-w3schools_io-box-4-0');Here is an example, dynamic types hold multiple values of different types. The is operator in Dart checks the type of a variable at runtime and returns true or false depending on whether the variable has a predefined type. Here's an example: var year = 1990; print (year) //The result is going to be: 1990. view raw main.dart hosted with by GitHub.
