Dart List — Code Snippets Part 1

This article will give you the most important List Code Snippets. The full documentation can be found from api.flutter.dev website.

What is List in Dart?

An indexable collection of objects with a length is called List.

  1. Fixed length — The Dart will give you an error when you try to change the length of the list.
  2. Dynamic length (growable length)

Okay. Lets jump in to the code snipits.

Constructors

  1. List.empty({bool growable: false})

2. List.filled(int length, E fill, {bool growable: false})

3. List.from(Iterable elements, {bool growable: true})

4. List.generate(int length, E generator(int index), {bool growable: true})

5. List.unmodifiable(Iterable elements)

Properties

  1. first

2. isEmpty

3. last

4. reversed

5. length

Conclusion

I hope this article will help you to quickly understand and get to know about constructors and the properties of List. The Part 2 will contain the methods of List. Once the Part 2 get published this article will be updated soon.
