always_use_package_imports

Avoid relative imports for files in lib/.

This rule is available as of Dart 2.10.0.

This rule has a quick fix available.

Incompatible rules: prefer_relative_imports

Details

DO avoid relative imports for files in lib/.

When mixing relative and absolute imports it’s possible to create confusion where the same member gets imported in two different ways. One way to avoid that is to ensure you consistently use absolute imports for files within the lib/ directory.

This is the opposite of ‘prefer_relative_imports’.

You can also use ‘avoid_relative_lib_imports’ to disallow relative imports of files within lib/ directory outside of it (for example test/).

BAD:

import 'baz.dart';

import 'src/bag.dart'

import '../lib/baz.dart';

...

GOOD:

import 'package:foo/bar.dart';

import 'package:foo/baz.dart';

import 'package:foo/src/baz.dart';
...
