Functions (With Optional & Required Parameters) - Flutter | Dart ~ Episode 1.4

Hey Coders! I like to think of functions similar to variables when coding in Dart. The difference is when creating a variable, you are storing a single piece of data to be used at a later time. When you create a function, you store an entire code block to be run later down in your code. Why store a block of code as a function instead of just running it immediately when you need it? There will be times when you need to run that section of code many times, and storing it as a function enhances its reusability, not to mention the code's overall readability. In this video, we'll examine how to make functions in Dart, accepting optional and required parameters, and lambda functions.
