no_leading_underscores_for_library_prefixes

Avoid leading underscores for library prefixes.

This rule is available as of Dart 2.16.

Rule sets: recommended, flutter

This rule has a quick fix available.

DON'T use a leading underscore for library prefixes. There is no concept of "private" for library prefixes. When one of those has a name that starts with an underscore, it sends a confusing signal to the reader. To avoid that, don't use leading underscores in those names.

BAD:

import 'dart:core' as _core;

GOOD:

import 'dart:core' as core;

To enable the no_leading_underscores_for_library_prefixes rule, add no_leading_underscores_for_library_prefixes under linter > rules in your analysis_options.yaml file:

linter:
  rules:
    - no_leading_underscores_for_library_prefixes
