Does Dart have import alias?

Question

I found myself written tedious code when importing files into dart files like the following:

import '../../constants.dart';

I'm wondering if there is any way to create an alias to specific folder like:

import '@shared/constants.dart';

Thanks, Javi.

It's not an aliases, but in Flutter there is way to make one import, which includes some different imports. Maybe it can help to shortened your imports — Andrii Turkovskyi, Dec 12 '18 at 11:24

Dart doesn't allow you to rename imported identifiers, but it allows you to specify an import prefix

import '../../constants.dart' as foo;

...

foo.ImportedClass foo = foo.ImportedClass();

It allows also to filter imported identifiers like

import '../../constants.dart' show foo hide bar;

Barrel files can also make importing easier like

lib/widgets/widgets.dart

export 'widget1.dart';
export 'widget2.dart';
export 'widget3.dart';
export 'widget4.dart';

lib/pages/page1.dart

import '../widgets/widgets.dart';

Widget build(BuildContext context) => Widget1();

That's not what is asked for – Rémi Rousselet Dec 12 '18 at 11:13
I see. No there is no such thing. You can use `package:my_package/...` imports but that usually isn't shorter. – Günter Zöchbauer Dec 12 '18 at 11:15
As commented by @RémiRousselet, I'd go for that solution. Cheers guys :D – Javier Rodriguez Dec 12 '18 at 11:37

I just want to say thank you. As I past about 3 months learning Dart / Flutter, I easily know some basic concepts from your answers on Dart / Flutter topic on STO. – Prabowo Murti Sep 29 '20 at 06:47

No. Dart do not have import alias.

But you have absolute imports which makes up for it:

import 'package:my_lib/shared/constants.dart

This will import the file /lib/shared/constants.dart

Worth noting that `my_lib` equals the `name` of your project in pubspec.yaml. – publicJorn Apr 26 '20 at 05:08
