Destructuring Lists in Dart¶

Did you know?

Since Dart 3, you can easily destructure lists using the spread operator (…).

Very handy for getting the first and last value. 👌

Note that if the list has only one element, you’ll get a pattern matching error at runtime!

So make sure your assumptions are correct before using this. 👇

This example was taken from Pascal Welsch’s talk about “Exploring Records and Patterns” at FlutterCon.
