for Loops
Explore the use of for loops in Dart to run code multiple times with control over iteration. Understand how to iterate through lists and sets, use the for-in form, and apply conditions within loops to perform selective operations.
Introduction
You have to print 100 copies of a document. Imagine having to print each copy individually and pressing print 100 times. It’s a lot more efficient and easier to just tell the printer to print the 100 copies and press print once.
The printer is performing an operation (printing a document) repeatedly in a loop until it reaches its goal (100 copies).
In computer programming, we sometimes come across scenarios where a block of code needs to be executed multiple times.
Dart provides for loops for this exact purpose.
Control flow
Let’s look at the general control flow of a for loop below.
The for loop allows us to specify a range of numbers over which we want our loop to run.
The iterator ...
