Does Dart have import alias?

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();

dart flutter dart-pub

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
