Dart Loops

Advertisements. The while loop executes the instructions each time the condition specified evaluates to true . In other words, the loop evaluates the condition before the block of code is executed.

The while loop is used when the number of execution of a block of code is not known. It will execute as long as the condition is true.

Dart do while loop executes a block of the statement first and then checks the condition . If the condition returns true, then the loop continues its iteration. It is similar to Dart while loop but the only difference is, in the do-while loop a block of statements inside the body of loop will execute at least once.

do-while loop is a type of indefinite loop . do-while loop first executes the statements and then check for the condition. If the condition is true it will keep executing and if the condition is false loop will terminate. So whether the condition is true or false, do while loop’s statements will execute at least once.
